What gases are in a scuba tank? The majority of gas used in most SCUBA tanks is compressed air. This air is composed of the same elements everywhere - 21% Oxygen 79% Nitrogen. Advanced SCUBA divers may use an enhanced mixture of 32% (up to about 40%) Oxygen with the balance being Nitrogen. The number of divers who use a mixture like this is about 2 to 5% of all certified divers.

Sour mix Sour mix. Sour mix, also known as sweet and sour mix or bar mix, is a mixer made of lemon or lime juice and sugar syrup. It is an important part of many cocktails. To make your own, mix one part heavy sugar syrup (3 parts sugar, 2 parts water) with one part lemon juice, and add 2 egg whites per liter of mix. The egg whites are optional, but will make the drinks slightly foamy. You may want to adjust the sugar/juice ratio to give the mix the right balance of sweetness and tartness.

Bends Oxygen is continuously used by the body, but nitrogen is not used. When a diver ascends, the pressure decreases and the blood can no longer hold all the nitrogen dissolved in it. * caisson (KAY-son) means a watertight container that divers or construction workers use under water.

Types of Mixtures The liquid homogeneous and heterogeneous mixtures are many in chemistry. The petroleum is a mixture of variety of hydrocarbons.Various pharmaceutical compositions are mixtures of compounds. Blood is a colloidal solution and natural gas, LPG, etc are the examples of mixtures in chemistry.

Scuba Divers Dalton's law refers to the effects which partial pressure might have on divers. This law says that the pressure of mixed gases is equal to the pressure produced by the individual gas. It can also be explained by saying that the total pressure of a mixture of gases equals the sum of the partial pressures of…

Trimix (breathing gas) The main reason for adding helium to the breathing mix is to reduce the proportions of nitrogen and oxygen below those of air, to allow the gas mix to be breathed safely on deep dives. A lower proportion of nitrogen is required to reduce nitrogen narcosis and other physiological effects of the gas at depth.

Scuba Cylinders And while most recreational divers carry a single bottle, there are also twin tanks that share a single regulator or even feed separate regulators for more advanced diving. In some diving documentaries you may even see futuristic looking backpacks that contain specially designed scuba cylinders.

- Mixtures. A mixture is made from different substances that are not chemically joined. For example powdered iron and powdered sulphur mixed together makes a mixture of iron and sulphur.They can be separated from each other without a chemical reaction, in the way that different coloured sweets can be picked out from a mixed packet and put into separate piles.or example powdered iron and powdered sulphur mixed together makes a mixture of iron and sulphur.

Breathing gas Hydreliox is a mixture of oxygen, helium, and hydrogen and is used for dives below 130 metres in commercial diving. Hydrox, a gas mixture of hydrogen and oxygen, is used as a breathing gas in very deep diving. Neox (also called neonox) is a mixture of oxygen and neon sometimes employed in deep commercial diving.

Gas Laws Save Lives: The Chemistry Behind Airbags Inside the airbag is a gas generator containing a mixture of NaN3, KNO3, and SiO2. When the car undergoes a head-on collision, a series of three chemical reactions inside the gas generator produce gas (N2) to fill the airbag and convert NaN3, which is highly toxic, to harmless glass.Sodium azide (NaN3) can decompose at 300oC to produce sodium metal (Na) and nitrogen gas (N2). typical airbag contains 50.0 g of sodium azide, NaN3. Upon impact, the airbag deploys and inflates within 40 milliseconds to a volume of about 60 L, at a velocity between 150 and 250 mph. The airbag inflates due to the decomposition reaction of NaN3 and fills with nitrogen gas in the following reaction:

Simple and Fractional Distillation Azeotropes. An azeotrope is mixture of two substances in a certain ratio that doesn’t change. For example, water and benzene form an azeotrope that is ~9% water by mass and 91% benzene.This azeotrope boils at 70 ºC-and remains an in this ratio in the gas phase.zeotropes.

What is a Homogeneous mixture? A heterogeneous mixture is a type of mixture in which the composition can easily be identified since there are two or more phases present. Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances.alt Water is a homogeneous mixture. A heterogeneous mixture is a type of mixture the composition of which can easily be identified since there are two or more phases present. Air is heterogeneous, because it is made up of different elements: Nitrogen, Oxygen, Neon, etc.

Breathing gas Gas blending (or Gas mixing) of breathing gases for diving is the filling of gas cylinders with non-air breathing gases. Filling cylinders with a mixture of gases has dangers for both the filler and the diver.

Homogeneous Mixture: Definition & Examples Homogeneous mixtures are also referred to as solutions. While we normally think of solutions as liquids such as soft drinks and lemonade, they can actually be in the form of solids, liquids, and gases. Homogeneous mixtures can also be a combination of these forms, as in a liquid-gas mixture.

- Air is a mixture of gases, predominately oxygen and nitrogen. Oxygen is a pure gas element. People at high elevations experience thin air, which can cause shortness of breath. Divers use various mixtures of breathable gas, including ones that contain oxygen and helium, when they explore the seas.
