So, these are the familiar expressions that we know already for any LTA vehicle for the net lift, gross lift and the weight of the lifting gas. What about whatever value net air? That is going to be 0 here, okay. So WBA will be equal to 0. What else will change if it is a rigid airship? What do you think will change? See we are not looking at the structure weight for anything so far. So why should it come for rigid airships? In all our discussions we are only looking at now the static lift produced by the system. So in static lift of the system we are not concerned about the weight because we are looking at, so now what about the super pressure, will you have any super pressure in rigid airships? No because you are not going to inflate the rigid airship at a pressure higher than atmospheric. We do that in a normal rigid, non-rigid airship because we need to maintain the shape. Here shape is maintained by the structure so therefore there is no super pressure. So PSP terms will go 0. Similarly, volume of the lifting gas will be equal to the net infraction, fraction I times VENV where this I is basically summation of IN VN upon VENV that is the volume of the lifting gas. So put this in the expression and you will get that the lifting gas instead of using VENV we will use directly V lifting gas because envelope is not containing the entire gas. The gas available is only VLG. Similarly, WLG we will knock off this delta PSP here and we will knock off this VENV as actually IN to VENV is already there. So catch up this IN VENV and replace it with VLG. So these are the changes that will happen if you have a rigid airships. Now let us look at another form of LTA vehicle which is the super pressure balloon. Now this is a very interesting system about which we should spend couple of minutes understanding. So a super pressure balloon is basically a balloon which is generally made of very thin fabric, very thin envelope material and we inflate it on this at the sea level or low altitude with less amount of LTA gas just enough to lift it up. Remember that as it goes up the envelope starts expanding because of the loss in the ambient pressure due to which there will be a pressure difference. Ultimately at the desired altitude or at the altitude where you want it to be deployed, it will occupy the maximum shape. If for some reason if the pressure has to, if the pressure falls, if the pressure becomes more than that pressure, there can be a pressure release valve also if needed but it will occupy the maximum shape when it is at the desired altitude. So the VENV is going to increase as it ascends. However the infractions will become now more than 1 because the volume occupied by the lifting gas at the altitude will be less and that volume will become larger and larger till it reaches equal to the total volume of the envelope. Secondly, we again have no balloonettes in this case so therefore the WBI is going to be 0. So you can change the expressions and get it. Now let us look at the hot air balloon which is what you are going to design. You have to ask the hot air balloon so you should pay more attention to this particular term. What happens in a hot air balloon? So please tell me, what happens in hot air balloon, do you have balloonettes? No. What about the infraction fraction? 0 or 100? 0. 0 means no gas, no lifting gas. That is possible if you put vacuum, if you fly with a vacuum. So I will be equal to 1 that is the infraction fraction and WBA will be equal to 0. So once you do that, WBA term will be cancelled and wherever you use I you have to put equal to 1. So these are the expressions you will get. I am just putting it here. If you also ignore humidity effects then E will be equal to 0 and then you got this classical formula which is used by balloonists. So what do balloonists do? They are interested in the net lift that is available because that is useful weight. If this net lift, now we come to the aircraft of the system weight, if this net lift is less than the weight then it will not go up. So net lift first thing you subtract is self weight, remaining will be payload that is how much you can take it up. So the net lift available will be the ambient pressure PS times temperature of the lifting gas which is inside the balloon minus temperature of the ambient air, this should be T subscript A, I will correct that, divided by TA into TLG times K into VENV where K is a constant. So when you design your balloon you can use this particular formula if you can convince yourself that in Mumbai you can ignore superheat. I do not know whether you can do that, probably you cannot do that. You must consider superheat when you fly your balloon in Mumbai at least because you know our atmosphere is actually having very high humidity and humidity is going to subtract from the lift. If you notice the terms which represent humidity basically this term 1 minus ID VW, WV into E, this term is a subtractive term which means the net lift is going to be, the net lift if you see the net lift is going to be less because of humidity.


Hey Psych2Goers, welcome back to our channel and thank you so much for all the love that you've given us. Your ongoing support has helped us make psychology and mental health more accessible to everyone. As a quick disclaimer, we wanted our viewers to know that this is a fun activity video, and this video should not be taken too seriously or used as any kind of diagnostic criteria. With that said, let's continue. Did you know that not only do you have a physical age, which changes with the ever-turning wheel of time, but that you also have a mental age that will never change? Different from your physical age, your mental age is how old you are emotionally and psychologically.  As an adult, you can have a low mental age, processing a childlike view of the world around you. A young person can have a high mental age, indicating that you're wise beyond your years. It's important to note that mental age is also not your IQ number, but rather an expression of how you feel inside. Figuring out what your mental age is is a great way to become more self-aware. If you'd like to learn about your mental age now, grab a pen and paper, or open up the Notes app on your device. You can take this fun quiz to determine your mental age. There are 10 questions to answer, so make sure you mark your answers as we go. Let's begin. Number one, what do you usually do when you make a mistake? A, admit you made an error and try to fix it. B, try to figure out why you made the mistake in the first place. Or C, laugh at your silly mistake and ask for help so you don't make another one.  A, tell them it happens and find another way to spend your time. B, feel upset about it but move on eventually. C, try to find another day to hang out and have fun together. Number three, how would you normally react if someone was angry with you? A, give them space to be angry before talking to them. B, try to work things out right away. Or C, tell them jokes until they forget their anger. Number four, what's the first thing you would do if you won the lottery? A, pay off your bills and put the rest in a savings account. B, go on vacation and make new happy memories. Or C, buy that cool thing you've been wanting for a while. Number five, what's the first thing you would do if you had to choose between two equally good things? A, think on your previous experiences so you make an informed decision based on facts. B, make a list of pros and cons and then choose the option with more pros. Or C, ask someone for their opinion and do what they suggest. Number six, how do you usually handle a major disagreement in the workplace or in school? A, calmly discuss the disagreement and try to come up with a compromise. B, go to a supervisor or teacher who would be able to help figure out what to do. Or C, get the other person to see your side of things. Number seven, what would you usually do if you had a big project due tomorrow? A, get started on it right away so you'll be able to relax later. B, take some time to relax first and then start working on it as soon as you're done relaxing. Or C, alternate between working on it and taking breaks. Number eight, which of your responsibilities would you eliminate if you could? A, paying bills. B, doing laundry. Or C, picking up after yourself. Number nine, how would you habitually react when someone compliments you? A, accept the compliment and give them one in return. B, accept the compliment and thank whoever complimented you. Or C, don't accept the compliment by saying you don't deserve it. And number 10, how do you normally respond when you embarrass yourself? A, acknowledge and validate your feelings but realize it doesn't matter in the long run. B, try to pretend like nothing happened but internally obsess over the feeling of embarrassment. Or C, feel upset over it and possibly even cry. Okay, are you ready for your results? If you got mostly A's, your mental age is between 40 and 55. Your mindset is more so self-assured and secure. You tend to think about things in a matured manner.  You struggle with finding your way and though it may be difficult, you always wind up on the right path in the end. If you answered mostly C's, your mental age is between 10 and 20 years old and your perception of the world is young and bright. When I took the test, my mental age was rated higher than my chronological age. And I agree with my results. I've always kind of felt like an old soul. Do you feel like your mental age is aligned with your actual age? What score did you get? Let us know in the comments below. Don't forget to like and share this video if you had fun taking the quiz.

d hot sauce. He made me my own bottle. I don't know if you guys saw it. He has its own brand that he gave to me. He didn't have my face on it, but it's a he made me a custom order one. The point being that dude, I think he's making about 10 million dollars a year selling hot sauce out of Texas and he sells it online and he sells it in stores. You can do both. So hot sauce. Big money maker. Lacroix. Big money maker. You know how much it cost you to do water brand? This water probably costs him three cents in the cans, probably 15, 18 cents. They sell this for a dollar. What else we got? Candles is a good business, man. I know a guy. A guy came to visit me from Germany about two years ago and I was at this conference and they had an after party and we went back to this party in Hollywood and I talked to him for like two hours. I think he was making about a million dollars a month doing candles and what he was doing, he was doing a free candle like if you signed up and then I forget how it was, but it was a free trial. It wasn't a trial. It was like a free bonus set. So people, he would lose money the first month because he would ship you like 10 candles for like $10 or something and he would lose like 50 bucks, but then people will come back, repeat buyers and he was making, I think he was making a million a month. Maybe it was more than a million a year, but candles dude, like candles, that's like candles. I don't know, I don't know how to make it easier than the word candles. Chocolate. I'm getting ready to get in this business. Chocolate, one of the most addictive things. Coffee, exotic coffee box.   You review different coffee. You build up a small following on social media. You start out making an extra hundred bucks a month. These look good. I might eat one of these while we're premium baking chips. I need some energy. You can do better. Although this is dark chocolate. This would taste good in a cookie. What else do we have? Clothing is great. There's a guy fashion Nova. He started his own fashion brand. You've probably seen it on Instagram. I think he's making like 300 or 400 million bucks a year. That's a lot. 300 or 400 million. Kylie Jenner built the quickest biggest company in history. It's doing, she did 430 million in 18 months and she's under 21. It's insane. It makes me laugh. Like she's like faster than, she grew faster than L'Oreal, Maybelline, all that kind of stuff. They're shaking in their boots, man. Ty, you're supposed to let them melt in your mouth. Ty, I have built houses for my mom and I've met Kobe Bryant so I can do business with him. Okay. What else is this? Oh, new chocolate. You want some? Yeah. Steve, Adrian loves food. He's instantly goes, yes. All right. I'm going to get off here. I'm going to keep this up for 15 minutes. Giveaway. Oh, let me do a giveaway. Click the link or we can talk a lot of stuff. Man, this is good. This is stevia, not sugar. Tylovis.com slash online income. Ty, stop eating chocolate. No, the only reason you become an entrepreneur, when you make your own money, you can do whatever you want. If you only want your live stream and eat chocolate, you need chocolate.  I'm serious. A lot of people, that's the number one thing, reason I became an entrepreneur, by the way. Oh, this is my piece. Adrian, Adrian, you literally watched that chocolate drop like when I drop food with my two German shepherds. She's like, no, that's still good. Ty, do you sleep? Yes, sir. Eight hours, man. All this stuff about sleeping less than eight hours, it's not smart. Now, a few people, Arnold Schwarzenegger, I got to interview him. I was at his house. He told me he only, he's always only needed five hours of sleep. But here's my answer to you.  You know what, Arnold Schwarzenegger is a freak of nature. The man at 18, he won seven Mr. Universes by 26. So yes, if you've won seven Mr. Universes and have special genetics, feel free to sleep five hours a day. The rest of regular human beings, if you're LeBron James, you can do special stuff. But you ain't LeBron James because you wouldn't be watching this right now. If you're LeBron James, I don't know what you'd be doing. He signed a hundred million dollar Nike contract. He's probably in the gym right now. So anyway, eight hours of sleep, some people I think can do seven. A lot of people need nine, man. A lot of people need nine. I read an interesting book on that. This book said that average person needs nine. So, Ty, most surprising human you know? Who's the most surprising human I know? Surprising in what way? Like Charles Manson? Like mass murderer? I don't know Charles Manson, by the way. But he's dead now. Who's the most surprising person I know, Adrian? Zach Cookman, somebody said, my friend Zach. Dwight Shroot from the office, Rainn Wilson. I know him. Beats, Bears and Battlestar Galactica. How about that? Elon Musk? I don't know him that well. I've had interesting conversations with Elon Musk, but I wouldn't say he's a friend of mine. I just talked to him. We go to the same event. So who else do I know that's interesting? Well, I mean, I just looked up, looked list off names. Acon, OT Genesis, Rap, Kevin Hart. I, but I'm, Kevin Hart is somebody also I don't know that well. I just, we go to the same things. But Tio, football, I don't know. I know Tom from MySpace. That's a freaking kind of bizarre person to know. When I was, I remember back in 2006, Dan, you wanted to meet a girl in Los Angeles, MySpace. Dudes were sitting there on MySpace. You know that he told me at the peak, 10% maybe more of the entire internet activity was on his website in the world. Like it was, I think it was 20%. And you know what most of that was? Dudes trying to do MySpace girls. That's pretty much where, and he told me, it's an interesting thing. Remember I told you about visualizing? When he built MySpace, he was in the mode of, he was in the mode of building a dating site. But he said people don't want to go on a dating site. So he named it MySpace, a place for friends. So people could pretend they were just there for friends. But I mean, you should go watch my interview with them. He said at the end, off camera, he said, Ty, you just got things out of me that nobody in this world knows. I never told anybody. So it's a little free thing. All right, I'm going to get off. I'm going to give away this thing. And then I'm going to keep it up since I keep talking longer. I'm going to keep this up for 20 minutes for all of you who need enough time to get in the program. For those of you who did get in, congratulations. You've got the it factor. Now you got a blueprint. Now you're going to be getting the mentoring. Now it's more on you, the it factor. I want you to have that. It's deep within most people. It's buried by the school system. It's buried by the government. But it's there. It's there. People go, oh, where does confidence come from? Where does charisma come from? It's there.    So even the dumbest person that we meet has massive computational power.  Remember, you can still procrastinate sometimes. You can still be discouraged. You can still be human. I told you 51%. If you're 51% better than the average person, you'll be doing good. Yeah, that's a good idea. I'm going to give away a mentor box too. Can you grab that under there? So I'm going to give away an extra giveaway. That was a good idea. This is a company, that one that I showed you that's doing about 900,000 a month. So it'll be free branding and free. I'm not going to open this. It has two books, worksheets, memory tools. Let's give this away first. Then I'll give away this. So we'll send you one mentor box, absolutely free. We actually have a new box design coming out too. That's cool. What does that say? The hell? Oh, that is mentor box. It looked like, man, that camper turned it around insane. Look at that. It looks like Zockpragma. Okay, so we're going to mail this to you. The question is, how many external factors of success did I say there was? How many external factors? I said there was one internal factor, the it factor. Someone said seven, no. Someone said Tai Lopez is the most powerful Filipino in the world. I am zero Filipino, by the way. I did my DNA. I have 0% Asian and I'm 0% Middle Eastern. Sometimes people wonder if I'm Middle Eastern or Greek. I'm not. Pretty much German mostly, but I look like my dad. I do not look German. I know I'm like 61% German. I'm 6% black. I am 9% Native American. I'm 1% Swedish. I'm 5% English. I'm Italian. I'm Spanish. So that's what I am. Okay. Okay, let's go. What do we got? I got to do a race. There. McDarkon 2 is the answer. All right, let's get away with this mac before it ends here. The question is, what are, what is one of the three factors of success that I said? What is one of the three? Ari, I see you out there from Norway. Rapper. Okay. What are the three factors? Name one of the three factors. What are they? One of the three factors. Self-education was not one that I said. Patience was not one. Visualization, nope. It factor right there. The oldie goodie on Instagram. We're sending you this laptop. The it factor. Thanks so much. I'll keep this up for 20 minutes. Go to this link here or go to the link in the caption. And congratulations to all of you who got in the test group.


Hello everyone, this is Amit Don of AmitDon.com. Today I'll have another episode of Calgary Walk video and I'll be walking starting from 6th Avenue Southeast and corner of Central Street South and then I'm just going to turn on the next block which is 7th Avenue South and Then we're just going to walk along the sea train line for a little bit So right now in front of us is the head and we'll just you know go nearby And let's take a look at the building first. We have a nice building right here So if this is your first time here on this channel, I'm always trying to get different ideas So if you appreciate variety, uh, please go ahead and subscribe And uh, I'm going to have a few videos from Calgary because I'm on a trip in Calgary and the Banff area So that's why you're seeing some Calgary walk videos So we are getting closer to the head and Looks like you can actually go inside so let's uh Go in here This is the name of this sculpture That's how It looks like from inside It just looks like a huge cage So this is downtown Calgary And My hotel is actually just around the corner So center is south and we're going to make a left turn here And Just notice this another nice building right here. So today is not that cold Uh, I think it's about plus five temperature, but it was minus five minus 10 couple of days ago So Calgary is colder than Toronto Turn here So the tower you're looking at is the Calgary tower We're going to look at the head from here or right here You're looking at the head from a distance So 7th Avenue south is coming up and that's where I'm going to turn And this is a sea train line I saw there are two different types of trains, uh, blue and red And they run different You know, uh So I'm planning to take the train once Or more than once, but probably not today So you're going to make a left right turn here not left. So you're just going to Walk Right along it and you can see there's train coming So you have automated tickets machine and I believe it's 350 per trip for two hours The name of the station is fast is fast streets out west So I see there is a train coming a little bit here for the train to arrive And then you're going to look at look at the train And then I'll continue. So if you look far You can see that the train is coming. So just wait here for a few seconds Nice angle new southwest if you look at the Transit buses, they look different than this one looks actually different Different color the backside of Hudson Bay has to be an old building So you just cloudy earlier today, but now looks like the sun comes out But it's going to be dark soon. So it looks like a small plaza We have another train here. So we are approaching another station So this video I'm going to end here and there'll be more Calgary rock videos. So thank you for watching. There will be more videos coming up. So I'll see you shortly. Thank you


Good morning. I'm Mary Ellen and today I'm going to talk about two favorites from the month of May And I'm going to talk about my family because they're my favorites also My very first favorite is a collaboration That my dear friend Mary from the channel glitzy fritzy did with Sydney Grace eyeshadows I'm going to talk about the eyeshadows in a minute, but if you'll just bear with me You may learn something new about Mary. I've known Mary She was the second person I became friends with on YouTube and she has been such a pleasure to know In fact Jim and I went to where she lives and met her and had lunch with her and enjoyed ourselves so much But if it was not for Mary, I would not still have my channel back in the day. I was Sensational after 60. That's what I started with because I really believe that life is Sensational after 60 loved every decade, but there's something Wonderful about the 60s and I'll know in a few months How the 70s are but but I can't imagine them not being fabulous Well, I got a cease and desist letter stating that I could not use the name Sensational after 60 that it was already trademarked and I had no idea what to Do and Mary who is technically gifted Helped me do everything to get my channel name changed and there was a lot of technical things to do and that's when I became Mary Ellen after 60 I Went even though I still color the roots of my hair or I haven't colored every three months. I Went on Mary's journey. Here's it. I'm gonna put a photo of Mary before she went naturally gray And I went on that journey the whole way with Mary She would be in that picture She was wearing a wig and so she decided just to keep wearing the wig and just to see what her hair would look like if she Didn't color it and I kept saying to her when she started to get weak I would say Mary just keep wearing the wig You can always color it if you don't like it because I just had a feeling that she would have beautiful silver hair unlike me who's Gonna be mousy I've got to get a lot more before I can go silver, but I looked at her channel and she has 37 Sydney Grace Sundays where she did makeup only using Sydney Grace eyeshadow and Sydney Grace is a cruelty and vegan Company and also they don't offer affiliates if you talk about Sydney Grace eyeshadow and you put a link to their Website nobody earns anything. They do offer discount codes I don't have one but nobody but if you use the discount code it doesn't earn that person any money So the people who love Sydney Grace love it unselfishly Several years ago Mary's told me she was already making the palette of her dreams Mixing colors mixing shades Because one of these days it was her dream to do a collaboration with Sydney Grace and It happened Mary created the blessed palette and these are the shadows. I'm wearing today There's a light version and a dark version and I'm gonna show you the shades But more importantly, I'm gonna link her video when she announced it and she went through what all the shades So why they're called what they're called how she came up with the Colors and how she wanted this done. There's not one ounce of glitter in here But I have a shimmer on my lid and I'm gonna get close so you can see Even though it is a shimmer It does not make my eyelids look any more wrinkled than they already are So and then I'm gonna talk about what I wore I'm filming this on Saturday morning. The palette hasn't come out yet But it'll come out the 7th, but I'm also gonna even though I haven't watched it I'm going to link Melissa 55's video. I saw this morning. She uploaded one using Mary's palette And I know it'll be great. So I'm gonna go ahead and show you what I'm wearing today This is the light palette and even though I just used it. You don't see any kick up anywhere How I use the palette is I just touch it.  I am wearing Shy guy, that's the purple purpley blue that's on my lids. I'm wearing peach This shade right here in the crease I'm wearing me after 60 which is halfway named for me in the corners a little bit of our savior I've lended right above the pita and then I have pop nongi Right in here, and I thought it created a very pretty look. I put on powder. I put on blush I put on lipstick I'm not gonna go into every every color, but I just want you to see how beautiful they are and I Love that she named it blessed because it truly is a blessing And this is the dark version and there's five shades in there that are darker For darker skins the rest of them worked for all skin ties, but there were five specifically for darker skin But to be 61 years old and to have a company want to do a collaboration with you That is remarkable. It speaks volumes about Sydney Grace And I believe they will be blessed by having Mary create this palette and all these shades in here Mary Created herself. She mixed and sent it to them and they'd send the shades back and see if it was right And they went back and forth until they got the perfect Combination the palette has sleeves that just go over it I'm just absolutely thrilled to death and I could not wait to talk about it Until Mary sent these to me and she asked my permission the only other person that I have accepted PR from is BK Beauty So, you know when I receive something I always do a giveaway and I want to buy it for someone else This isn't a giveaway video because I'm going to be announcing $500 worth of winners that I used my own money for so I've got to save up a little bit But I will be buying these if a company sends me something and I haven't purchased it I'll put a star by it But once I've purchased it I don't feel like I need to use the star because I put my money behind it But I could not be more happy. I am thrilled thrilled thrilled for Mary. I Couldn't happen to a better woman She truly has been a blessing to me and a blessing to so many of you the price of the palette is $52 you can choose lighter dark and Mary has a 15% off coupon and it makes it $44 and some change So I just wanted to make sure you knew that well the next one I want to talk about is BK Beauty I love Lisa J. I found her on her channel. She is a Was a professional makeup artist. She worked for Mac and I just started enjoying her videos Not positive how I found her but I really like her and she started her own company The name of her company is BK Beauty and that stands for be kind beauty and a percentage of her profits go to the Kindness campaign and I'm going to put a link to the kindness campaign because it is very worthwhile BK Beauty started out with brushes all different kinds of brush lines Wonderful. In fact, I have given away just about all of my brushes and my daughter and her friends are thrilled because BK Beauty brushes are my favorite Mary glitzy fritzy has a Sigma brush set for eyeshadows. I still have that and a few others, but I love Lisa's brushes I don't think I'll ever have to buy any more brushes. I take good care of them and they're wonderful And I'm not sure in the order. She did lipstick. She did eye shadow She did a collaboration with Angie from Hot and Flashy and created some great brushes there. Angie created them and Done false eyelashes Just all sorts of things and everything has been wonderful Well today before I put on any makeup I tried on all of these shades and for the video I ended up wearing gratitude I love this shade, but I wanted to film it without any makeup on I think I had on mascara I tamed my brows down with the ABH brow freeze and Some navy eyeliner and nothing else on my face when I put the lipstick on because I wanted you to see How easy it is to see if a color is Complementary to you and your skin and I wore black for that reason because for me It is the most neutral if I put on white my skin looks brighter my skin but my skin looks neutral in black So I'm gonna go ahead and show that this is grace. It doesn't do anything for my complexion It doesn't bring out any brightness But it's really good to mix with other shades if you have something that's a little bit too dark Many people would use a lip liner But you know I'm a slacker and I really have to think about it before I use a lip liner But this is grace. This one is beauty. I can already tell it's one that I'm gonna like It does something for my complexion And I love what she calls the shades. I just really appreciate something positive and The next shade is gratitude to swipes and I really like it You can really see what shades of lipstick you look good in if you don't have on any color on your face I have on mascara Now I saw Tamara from Tamara's timeless beauty apply this lipstick and it really looked good on her And we I'm usually drawn to the same shades that she wears But I'll put it on and I want your opinion. This is called empower I can't wait to edit this video because like right now I don't like it, but I want to notice how it makes my skin look without any color on my skin whatsoever This is confidence. We'll see how confident I am. I think it's a beautiful color And I know it'll be even prettier when I have makeup on and this is faith mmm, it's a beautiful vibrant shade faith and One swipe and one swipe will give you this intense shade It's very comfortable. It isn't as long-lasting as like a long-lasting lipstick But I'll tell you I I still have it on six hours later If I don't put a lot of gloss on over it It'll stay if I wanted to I could do what my mom did my mom would blot on Tissue and then she'd reapply and And it would in her lipstick stayed a long time, but I just love the way these feel on my lips So that's my try on for you for her new six new shades Something different she did is she this time is she put the shade of the lipstick on the bottom the sticker It used to be plain and I really like that Her lipsticks are a very nice weight. I love the angle of them. I love that they are magnetic and If you turn one upside down You can get them to stick together If you do every other time like the stickers here and it's not there So now I'll put it not there and you can stack them, but I think that's pretty cool But you know me like little things. She also sent me the existing shades. It came out I think about a year and a half ago. I'm not positive. I have all these I used up two of them, but I have all three and I'm going to at some point put this in a giveaway But again, this isn't a giveaway video, but I will order some lipsticks When I do that giveaway so I don't have to put the star by it I'm gonna have to put the star by it today because I didn't buy these and when I talk about the star It's in the description in the show more section anytime if I mentioned something like I said if I didn't pay money for it My money for it. I put a star by it, but congratulations Lisa beautiful beautiful shades and Congratulations to Mary I Have my family's permission to put this photo in it's me My daughter Gretchen and my son and you can see we are in the middle and I want to talk about my grandsons I've just got a brag number one. They are all excellent students Excellent. Well, two of them are not students anymore The first one I'm gonna call him E It's really hard not to use their name. He just graduated from high school and he got a fantastic Scholarship to play basketball and I can't say where but it is a top-rated school that has a I mean a Top basketball program. He can't wait to work so hard and To get to earn the chance to play someday He's also the one that plays football that he chose basketball to continue his college career But he's six five and in these photos that the one next to him is a and He's going to be he says six four You know the way people stand in photos makes a difference a is starting his junior year July the weekend of July 4th football practice starts again He probably played 85% of the 80 or 85% of the season last year in football And he is a wide receiver and he is hoping to get to start in the game. So I always pray no injuries I pray so hard before each game that there is no injuries A will be back to school away from home and E the one that's just going to college will not be living at home They'll be living in an apartment. So he's excited about that E is my son's youngest son and a is my daughter's younger son and There's my daughter Gretchen and me and Jeremy who's kind of back there in the back and the next one is a Another a I have a lot of vows in grandsons and he graduated from college in 2021 and got a job about a month later in his field He works in with numbers and he loves what he does and I think he plans on staying because He bought a home.

Welcome. You're watching Life in the Law on Wednesdays from 1 to 1.30 on Think Tech, Hawaii. I'm delighted today to talk about something I'm participating in, and we have a great guest to talk about the local aspect of it. I'm marching in Washington for Women's Rights on the weekend, on the 21st, and Michael Golou, Golou, Golou, Golou, Golou you. I did it every time I said it. Is the program manager for the Oahu portion of the march. So we'll talk a little bit about the Oahu portion of the march, which expects tremendous crowds, and so does Washington. And then we'll talk a little bit about national and what you think is going to happen there. So welcome. Thank you for joining us. Well, thank you for having me. So what, okay, let's tell everybody, I guess, first of all, the story of how the part, the march, became, came to be. Well, on November 8th, like a lot of people, Teresa Shook, a wonderful grandma from Hana Maui, went to bed. She was in a chat room, basically, on Facebook called Pantsuit Nation, and she, everybody was commiserating with each other, and she's like, they had to teach her how to set up an event thing on Facebook. And so they taught her how to do it, and so she's put out there that she wanted to march on Washington on the day after the inauguration. She went to bed with like 40 people saying, yes, I want to do this.  Oh, really? If you're only a single person and you put up an event, it gets blocked at 10,000. So she had to develop a group in order to have, yeah. And then this sprung of the movement. It's actually an international movement now. There are over 700 sister marches. Really? Cappied all across the globe. I'm so proud that this idea came out of Hawaii. I can't tell you how proud I am. I'm like, well, my old friends in New York, I'm like, you see? You see what we're doing over here? You should follow us. So the idea is that women and men also are marching on Washington in support of our rights to protect our rights, our reproductive rights, and our rights to equal pay. What would you say? We're very adamant that this is not an anti-Trump march, right? This is a pro-women march. It's a pro-women. It's a pro-issues. It's a pro-policy. We are looking beyond the 21st. We're looking beyond that with the march. The marches, what we are hoping it will do is turn these accidental activists. Because if you look at who's running the national program, you have different, all these different people who don't really have a background in community organizing. But they've come together and they've put together an amazing program. And I encourage everybody that's watching to go to womensmarch.com. And you'll see all the stuff that they have together. You'll also see the sister marches. All over the country. All over the world. All over the world. What came online this week is really chicken skin time. It's when there's a women's march in Iraq. There's one in Saudi Arabia. Wow. So we're talking Nigeria. So women across the globe are being empowered by this to step up, not just women, but all and the men that support them and everybody else that supports it. And yes, it's called the women's march. But it's our social agenda of inclusion. And making sure that all minorities are taken care of and to send the message loud and clear to the incoming administration that we will not allow to the clock to be turned back on the advances we made. We are going to be here. You may not like it. You may not agree with it. We're going to be here. Our voices will be heard. Right. And it's going to be hard to not pay attention when you have as many women and their supporters show up on the 21st. Yeah, it's all like wildfire. It's just catching on like wildfire. So you told me that you were going to start at the Everplain. Is that right? The Everlon. Everlon. Everlon at the cap for O'ahu. We're actually beginning a little bit before eight o'clock on the January 21st to, there's a national moment of silence that happens at one o'clock East Coast time. So it's eight o'clock our time and we're going to participate in that. Okay. And so it's led by Gloria Steinem. And so it's a minute of silence and then a minute after that, silent no more. Excellent. And so it's going to be very, very skin tingling. Yes. Yeah. It's going to be very powerful. We're hosting a sign making session for the last minute people, because we have people that have contacted us or they're here on vacation and they want to take part of it. It's going to be amazing. So many newbies. So many newbs. Yeah. And people taking time out of their vacations. They're spending a lot of money to come to Hawaii and they're going to take a good portion of Saturday to come out and spend time in March and send a message. And so we were hosting that from eight o'clock one to nine thirty we're going to wrap that up. And we have a drum, an African drum crew coming in at nine twenty to get the crowd going. And then at nine fifty there'll be a quick high. Thank you. A quick overview of what the day and then ten o'clock the mark starts. Okay. And it starts on the Evalon goes down Richard Street, Richard's to King, King to Alipay, Alipay back to the capital. We have two left lanes. Thanks to the city issued our permit. Oh, excellent. So we're actually taking to the streets for this one. This is going to be, I think people are going to be really wowed and really moved because I vaguely remember Martin Luther King's March in Washington and I was very, very young. I probably was four or five years old. But the reaction of the people around me was what, I mean I was too young to process the actual event. But the reaction of the grown-ups was so massive it was like ripples in a pond. And I think that it's going to be really eye-opening because I'll tell you something. I know a lot of people that are conservative and even here in Hawaii believe it or not. And I don't think they realize the impact this is going to make. Just it's going to be like a bell ringing around the globe, you know. And it can be, it can be very, very powerful. Yeah, it's going to be very powerful because it's a non-partisan event. And like today representative Beth Foucaumoto and just at the Capitol when we were on another station for the morning show. And she's going to be joining us again on Saturday. And you see the groups that are joining us. We have 56 supporting organizations across the spectrum covering lots of different issues. Like I said, we had many Hoonie Water came on board. It was one of our supporting sponsors. They're going to be supporting donating water. We have Valley of the Rainbows came on board this morning. And so every day it's been growing and growing. And at this point it's become exponentially with the people at our RCP through Eventbrite with us. And people are like, oh, do I have to RCP? No, you don't have to. No, it just helps you guys. It helps us plan. And so it helps us instead of having to, we're still going to have to do the math to figure out how many people we're expecting. But we're expecting a nice turnout. And I believe we will help send a message because, well, this is going to kick off in New Zealand. One of the first marches is going to be happening in New Zealand. Hawaii gets to close it all out. It starts and ends with us. It started with Teresa Shook and it ends with us again. That's great. Like a parenthesis around the idea. And I think everybody needs to know that this is just a starting point. There's a real wave, a real movement among people to continue working hard, continue the struggle because it's going to be a struggle over the next few years. And we really don't want to have any rollback of any of the great things that we've been able to accomplish and we want to push forward. So I think this is sort of the opening act of a new wave of activism. I'm hoping it is. Oh, it is. We're hearing from women and men across the country and with the national organizations here in Hawaii. We're hearing from people that have never gone into activism. Right. This is, like I said earlier, accidental activists. And these people are making a point of coming out and being part of this. And they're like, this one lady wrote and she goes, I'm going outside my comfort zone by doing this. And she goes, but I'm bringing my daughter. Oh, well, yeah, that's great. And she's bringing it. We're going to see the next generation of activists hopefully be born out of this movement and be brought to and given the chance to have their say. And it's, people have opened their hearts and their wallets to us because putting on something in a huge, huge, it's not big. Expensive message. Where should they send money? If people want to send money. They send money. You can go online to women'smartialwahu.wordpress.com. We have a donation button there. And that's basically, we've been surviving on donations. We did some t-shirt sales that started off quick back in December. That gave us the seed money to move forward. We just, and then as the donations started coming in and so we, this is a truly grassroots movement and that's why we have the wordpress.com and we didn't have the money to go out and buy a URL at the time when we started this. And like I said, it's just been amazing. The outpour of Aloha from everything. And we've seen that for here on Oahu and it should be noted there's actually marches on, we have a sign with you on Kauai, the big march here on Oahu. And then we have Hana. It came on board last week where it all started. They're having a gathering at Hana Bay at 3 p.m. And then, let's see, Maui College at 8 a.m. Kona has theirs as well as Hilo. And everybody can find information from the same website. There's links to everything else. Right, it's all over the internet. Just type in women's march in Washington and you'll be loaded with information. But you know, I have to say, I really think that this is galvanized women because I think it was profoundly disappointing that, I mean, many women I know, many women my age and older were really ready for a woman president. We really, really thought this time had come. And it's a deep wound. It's a profound wound and I think that people, it's going to encourage people to work hard and to see the kinds of faces they want to see in politics and not the same old faces.  New ideas. Exactly. And making sure that we take care of everybody. And making sure that we... It was a very shocking Sherry, who's our senior in charge of the state coordinator. She said she was shocked when it happened. She realized we lived in a bubble that she thought that this couldn't have happened. This bully would not be elected and they elected the bully. And we're going to have to figure out how we deal with the ramifications of that for the upcoming generation, how we make sure we insulate and fix and make sure that everybody understands, the children understand you cannot treat others the way it is, just because he's doing it, it's not right. Right. Well, you know, I'm showing my age today, I think, but you know, I remember the profound disappointment when Richard Nixon was elected president and that was a really, really hard time. America was very conflicted. People didn't have... People's rights were really restricted and you know, and the guy was just a bad guy and you knew it, you knew it but people insisted on electing him, you know? And really, so I'm glad that I'm able to tell people, you know, we've been through hard times before, we've been through hard times with the president before, but we can get through it and we can push through it and we can prevail. This is not like a debt sentence, this is not the end of everything.  You can no longer be an armchair activist. You don't have to dedicate 24-7, but just be, show up every once in a while, put a little effort out there and you'd be amazed if everybody did that, what a better world we'd all live in. I couldn't agree more. You're watching Life in the Law on Think Tech Hawaii. We're going to take a quick break and we'll be back in a minute. Hello, my name is Crystal. Let me tell you, my talk show, I'm all about health. It's healthy to talk about sex. It's healthy to talk about things that people don't talk about. It's healthy to discuss things that you think are unhealthy because you need to talk about it. So I welcome you to watch Quok Talk and engage in some provocative discussions on things that do relate to healthy issues and have a well-balanced attitude in life. Join me. Hi, I'm Donna Blanchard. I'm the host of Center Stage, which is on Wednesdays at 2 o'clock here on Think Tech. On Center Stage, I talk with artists about not only what they do and how they do it, but the meat of the conversation for me is why they do it, why we go through this. A lot of us are not making our livings doing this and a lot of us would do this with our last dying breath if we had that choice. And that's what I love to talk to people about. I hope you enjoy watching it and I hope you get inspired because there's an artist inside G2. Join us on Center Stage at 2 o'clock on Wednesdays. Bye. Hi, you're watching Life in the Law. I'm Mary Ann Sasaki. I'm here with Michael Goulou-Loy. Say I try to correct myself, but I over-correct myself. So Michael is the program manager for the Oahu Women's March, and I'm going to march on Washington. I'm doing a crazy thing. I'm flying out on Friday, going to the march, staying over one night and then coming back.   It never goes away. Exactly. So in some ways it'll be easier than taking the bus eight hours around trip on a single day. So it'll be a whole new experience for me, traveling to go. So how many people from Hawaii are going? Do we know? Approximately. Approximately. We have around 200 people that we know of. Huge. Then you add in the people that are from Hawaii that are already in the mainland that have not, that we don't know for 100% sure. I'd say we're being close to four to $600 people. That's great. That would ties to Hawaii. And when we talk about the outpouring of Aloha, we've had Danny from Hilo, that made 200 tea leaf glaze. Right, the glaze. The glaze, those are being sent out tonight are travel coordinator. Amelia's already there. She left last night. What about Patagonia's donating? Patagonia donating. One where, which we'll need, because it will all be freezing. Yes. They were very generous in their donation to the team. Oh, the Ohana. And so it's been really exciting to see how many people this has energized and brought out. And all the passion and the drive to actually do more. And that, like you said earlier, this is not, it doesn't end on the January 21st. It's just the beginning. Right. Because like in D.C., they're going to have a rally. We'll have our rally after the March. And that's where you get the meat of it. It gets you inspired and you see other people. I remember on one piece, March I went to in Washington, I marched with a member of the Lincoln Brigade from the Spanish, not the Spanish, but the Spanish management with Lincoln Brigade 1930 Spain. Anyway, so he was so inspiring because he was in a walker. He was probably 90 years old. He'd been doing this since the 30s. Since he was fighting fascism in the 30s.  You just inspired by them, I think. You never know where inspiration is going to come for you. And they're going to be the stories that we're hearing coming from here locally and nationally about the people that are making the effort to go to D.C. And it's also the effort just to take, in some cases women are taking the day off of work because they work on Saturdays. Right. That's a huge, going is a huge thing. I mean, I'm humbled by the idea that 200 people are traveling this far to participate in something. I mean, I think that bodes well for the size of the crowd generally. I think people are going to be converging on Washington. I think it's going to be very difficult to, it's going to be very difficult to maneuver around there post, you know, post inauguration. So we'll be seeing what the remnants of that is too. Well, the other interesting part about that is there are 200 buses that requested a permit to park for the inauguration. 1200. Actually, I'm sorry, 14 plus for the women's march. People will be getting out in Virginia. Just make sure you know the train system because you're going to be out, out, out. That's why if, well, you know, the best way to go is by train, but unfortunately it's very expensive. But it's the best, it plops you right in the middle of things and it zips you right out of things. But I hear Union Station is going to be closed tonight for Trump rally. Yes. That's what I hear. Tomorrow night, I think. Oh, today's Wednesday. It's Thursday. You're right, exactly right. Yeah. And how odd. I know. So strange. He's already doing so much to disrupt everything in D.C. And I'm not talking about politics. I'm talking about people's normal lives. No, yeah, yeah, yeah. Day to day. Day to day. And so the reason he's doing this is just, who knows why? And it's part of people thinking he's trying to disrupt the incoming travelers for the women's march. And he might be. Because he's closing down the station? He's closing down the station for him to have his little rally. And I'm like... I don't understand why a president needs a rally. You're the president. The president-elect. Like the whole country is like your rally at that point. Now you don't have to sell anybody anymore. You just have to do, do, do. The only people that really need... The only people that are leaders that need rallies are fascists. Right, right, right. I'm just... My personal thing that's not... Early, early editorial on that, I mean, the comparison is just disturbing.  This right-wing kind of extremism is growing in every country. Even Sweden, places like that, a super liberal, Germany and France, it's... Did I say left-wing? I meant right-wing. Did I say left-wing? But it's super right-wing, super conservative, dictatorial, sort of... I would hate to say charismatic leaders, but strong leaders. It's a terrible trend. And people really ought to learn from history and read about World War II and what happened and how easily it could happen, how easily things like that can go upside down. And that's one of the reasons I'm really inspired by the Women's March, is that it's permeated the atmosphere and the culture and people... I went to the healthcare rally this past Sunday with Senator Schatz. And almost every woman I walked up to to try to give him a flyer. I already know about it. I already planned on being there. We're putting together a team. And I'm like, great. What's your team's name? And they say, I'm like, okay. You want to register? And they're like, why? And I'm like, well, because it helps us. And I explained who I was to a couple.  So a couple more registered. We have teams covering the gamut of all issues. And it's amazing to see that people coming together from different areas, different focuses, mental health professionals. We have environmentalists. We have, of course, all the different gamut of women's rights organizations. And we should mention the seeds of peace who are kind enough to host a workshop on Martin Luther King Day on Monday. And they're doing terrific work. Yes, they are. They're one of our founding sponsors for this to help make sure that this goes beyond the one day that we continue the fight, we continue the movement and figure out what we can do as a community to help move the needle forward or at least make sure it doesn't go back. You know, this is going to sound Texas, but I'm going to say it anyway. You know, when women get involved in an issue, that's a protein growth. I mean, when women got involved in the anti-war movement in the 60s, mothers, the expansion was amazing. You know, because women are used to working in groups and working in communities and having, they network, we talk to each other. That's how we network. We're very hands-on with our friends and we share our lives, share what we're doing. So naturally the word gets out. You know, that was like before Facebook. But when women are involved, things get done. And that's not one that are involved. It's not Texas. It's an actual fact. Because I've worked with all men's organizations before, and I will never do that again. It's a little more hierarchical. I call it, you know, women's movements like gossipy, but I say that in a good way. Because we talk and we talk and we share and we talk and we divide things up. You can do this, I can do this, I can bring this. You know, whether it's lays or we had a gathering and everybody brought a potluck, that's how we're used to operating. There's nobody in charge. We're all in it together, you know, to go forward. So that's how I think it's going to be in Washington, too. Well, there's, yeah, we've seen, because you have all these different women coming together, working together in different areas, because there's so much to get done. And putting on an event like this usually takes a year or plenty. Right, that's right. They've had eight weeks. Right. The magnitude for the amount of time is unbelievable. I'm going to take a little bit of a divergence here because we were talking about something that's really important to me. And I think it's really important to you. And that's the commutation of the sentence for Chelsea Manning, which, you know, I very much am in favor of. And I think you are, too. And what do you think this can mean for the future, for the LGBTQ community? Or just what are your thoughts about this commutation, this act of mercy by the president? When he commuted Chelsea Manning's sentence, it was something that would have never, your average person, ravaged whistleblower would have never been tried and convicted for releasing evidence of war crimes. And that's what Chelsea Manning did. Whether you can disagree or agree about the manner in which she did it, it needed to get out there. Right. Well, I think it's what she did was very brave. Yes. And I think what President Obama did is very brave, too. So, yeah, I wish he'd done it a little sooner. He didn't. But I take it as a parting gift from him to the LGBTQ community, a parting gift to the anti-war movement that, yes, war crimes shall not be tolerated, should not be tolerated. And that we need more people like Chelsea Manning to come forward when they see something wrong, say something. Absolutely. We're definitely going to need that now moving forward more than ever with this new administration that we are going to need people that are willing to have the fortitude to say something, stick their necks out when something like this happens. Right. That's asking a lot because you risk everything.  But think of all the lives she saved by speaking out and doing something. And so, yeah, everything there's a risk of doing something. And one of the quotes that I came across is, don't let fear of failure be your fear of inaction. Oh, right. No, of course not. Yeah. And you can fail by coming forward. And you can... Failure is a sign that you're trying. If you're failing, you're doing... If you're failing some percentage of the time, you're doing something right. Because if you stay in your comfort zone, you don't fail. But if you try and fail, hey, you're in there. You're in it. So, yeah. And I hope also, just personally, that Chelsea Manning will be happier because she'll be able to have a happy, integrated, rich life. Yes. And not be a member of the community and not be ostracized by the community because of what she did or anything. Just be happy. I hope she's happy. I hope so too. And I believe she should get her heroes welcome. I think so too. But I think we're in the minority. Well, we might be, but you never know. Well, on that note, you're watching Life in the Law. I'm Marianne Sasaki. I'm Marianne Sasaki. We are on Wednesdays between 1 and 1.30. Here on Think Tech Hawaii.


Hydrogen? What is the atomic number of hydrogen? What is the position of hydrogen atom in clear table? The position of hydrogen atom is clear table. It is above our law. Is it an alkali metal? No. Why it is not an alkali metal? It is not an alkali metal. Why because the definition of alkali metal is these are the metal which reacts with water and forms hydroxide. Like suppose N A is an alkali metal, reacts with water and forms hydroxide. N A O H plus half of H 2. Proceed? Oh yeah. So this kind of reaction hydroxide does not show. It does not react with water. So the definition of alkali metal is these are the metal which reacts with water but hydrogen does not react. That is why it is not an alkali metal.  They have water and they react with water. N A O H does not react with this. So even a hydrogen reacts with H 2 O, it will still get hydrogen H 2 O? No, it will not get. No reaction is there. The reaction is not possible. See why this reaction takes place? It is the reason that N A gives N A plus plus 1 electron. And then this H 2 O from this O H minus will get attached to this. Hydrogen does not react with water. That is the one thing. See the point is the position of hydrogen atom it is placed in the first group on the top. These are the elements. Why hydrogen is placed here? Because if you see the property of hydrogen it has only one electron in the outer motion. It has tendency to gain one electron and forms duplicate. It has tendency to release one electron. It has tendency to share electron. All three possibilities are there. So if you see these three properties, alkali metal has tendency to release one electron. Sodium, it releases one electron. This property is similar to halogens. This property is similar to alkali metal. And this property is similar to carbon family. So we have three different positions of hydrogen can be here with halogens or with alkali metals or with carbon family. Why it is placed in group one? Because its outermost electron configuration is what? 1 S 1. Since the electron configuration is similar to that of other alkali metals that is why it is placed in group one. So this is placed in group one but it is not an alkali metal. In LCRT it is here. I am not discussing this as to go through it that there are few properties it has similar to that of halogens. Halogens actually just say halogens has property to gain one electron high electronegativities. Hydrogen also has property to gain one electron. Yes, and halogens are diatomic also. F2, X2 will write F2Cl2Br2 like that. Hydrogen also diatomic, H2. Similarly for alkali metals also hydrogen has few properties similar to alkali metals. Like it is electro positive in nature this is also electro positive. So like that there are many properties the reducing character is also there. And few properties similar to that of so there are few properties which is similar to that of halogens, alkali metals and carbon family it is given in LCRT just to go through it was not that important. What we have to discuss here is the preparation of hydrogen methods of preparation of hydrogen and then chemical properties of this and few compounds of hydrogen the most important part of this chapter is hardness. Hardness is what? What is hard water and soft water? There are some reasons for hardness of water temporary hardness, permanent hardness what is the reason for that and what is the removal how to remove the hardness of water. So if you have 5 minutes suppose before the exam and if you want to revise this chapter you should revise hardness part of it. Mostly you will get questions from there. And then some structure of H2O2 that is it for this chapter. So right now next the preparation of hydrogen the first method is by the action of water on active metal first one by the action of water on alkali metals this is reaction of hydrogen preparation of hydrogen by the action of water on alkali metals alkali metals you can also take alkaline earth metals active metals the elements of group 1 and 2 reacts with water and evolves hydrogen gas reacts with water and evolves hydrogen gas next slide the reaction is exothermic in nature to slow down the reaction we use amalgam amalgam means the metal that you are using amalgam of that alloy with H2O2 amalgam we use because the reaction is highly exothermic and what we say very fast also very fast also amalgam see you have metal it occupies the surface of the metal it absorbs it absorbs on the surface of this active surface area decreases in this case that is why the rate of the reaction also decreases the reaction slows down isn't that the same as putting in less metal is it like more metal plus amalgam active metal plus amalgam active metal plus amalgam you have suppose the active metal is not there plus amalgam so that won't react at all this just decreases the surface area isn't that the same as just putting in less of the same metal without amalgam as if you have more surface area that reaction is also possible what happens reaction is highly exothermic and rigorous in nature so it's very difficult to control there are chances of catching fire also in nature because the high heat evolves to control that reaction we use amalgam so that the reaction slows down less the energy evolves and we can control the reaction for that purpose we use it without amalgam also without hg alloy also the reaction possible but the rate is very high okay next point to write down by alkali solution by alkali solution metals like beryllium zinc metals like beryllium zinc aluminium react with boiling alkali solution means at high temperature we heat this solution boiling alkali solution and evolves hydrogen gas and evolves hydrogen gas so what do you mean metals like beryllium zinc and aluminium what kind of category is that definitely metals of group 1 you can take or group generally we take elements of group 2 or group 1 metals active metals okay so second period element second group sorry beryllium with NaOH alkali solution what it forms hydrogen gas goes out and it forms sodium beryllium Na2 BeO2 is sodium beryllium and H2 gas evolves into this if you take aluminium it forms sodium aluminium so is it because of amphoteric acid what so is it due to the amphoteric acid amphoteric acid is not required here because we are not using acid here only basic solution okay what happens this beryllium can displace this hydrogen metal okay depends upon the electrode potential which we haven't discussed here it can displace hydrogen gas from this next slide down by the action of acid on certain metals by the action of acids on certain metals right on by the action of certain metals on acid right on certain metals which displaces hydrogen gas from the dilute acid solution by the action of acids on certain metals there are certain metals which displaces hydrogen gas from the dilute acid solution okay for example zinc plus H2SO4 what is the product here we can have mg plus 2Hz okay see these metals are electro positive metals these are electro positive metal these metals are placed above hydrogen in the electrochemical series okay electrochemical series again we will discuss this in electrochemistry somewhere in between we have electrode potential of hydrogen electrode which is assumed to be okay assumed to be 0 and above this we have positive electrode potential E0 greater than 0 and below this E0 is less than 0 so we can take all those metals which has positive electrode potential which and those metals can displace hydrogen from this dilute acid solution all these are dilute acid solutions so this gives you ZnSO4 plus H2SO4 and TCl2 plus H2SO4 so what is the difference between this series and the reactivity series reactivity series of what difference is not there but we can use this series this reactivity with respect to dilute acid I will explain this what happens here see actually hydrogen is present here one thing is there that if electrode potential is more then that metal has more tendency to go under reduction okay electrode potential means reduction in potential okay so if you have two metals suppose M1 and M2 if M1 has more electrode potential than M2 and if you form a cell of these two electrodes in this M1 will be the reduction of electrode where the reduction takes place which is cathode and M2 will be oxidation right so what happens here Zn plus 2 you see that oxidation of zinc is 0 here here it is plus 2 hydrogen is plus 1 and here it is 0 so which one is going under oxidation and which one is going under reduction Zn is getting oxidized and hydrogen is getting reduced right so what we can say when zinc reacts with this it displaces nitrogen right and rose under oxidation it means we can write the E0 of Zn plus 2 to Zn that means the reduction potential plus 2 to 0 is less than E0 is less that is why it is going to get oxidized it is less than the E0 of H plus 2 can be negative can be positive depends upon the matter there are certain metals which have negative electrode potential certain metals have positive electrode potential means this reaction means all those metals whose reduction potential is lesser than to that of hydrogen can displace hydrogen some its value ok one thing I wrote here wrong this should be negative and this should be positive so reactivity series is this only when you have metals which has more you know oxidation potential that will displace the other metal from its valued solution that is the reactivity series more reduction potential more reactivity more tendency towards the reduction reaction of that
