- Confidence votes 203. Air molecules is a little vague, the air that we breath is a mixture of mainly nitrogen (72% or so) oxygen and carbon dioxide. A water molecule is H20, two hydrogen polar covalently bonded to one Oxygen. Besides for the two bonds to H the oxygen also has 2 lone pairs of electrons.

- Atmospheric air consists of a variety of naturally occurring gases; including nitrogen, oxygen, carbon dioxide, hydrogen and the noble gases. In air these gases, apart from oxygen, serve little purpose to us however they are widely used in other places such as medicine, science laboratories and in the general world.

Atom The Atmosphere. The final sphere is one you've probably already heard of. This is the atmosphere, which is the air that surrounds Earth. This 'air' sphere is made up of mostly nitrogen, some oxygen and small amounts of many other molecules. Most of the atmosphere is densely packed near the surface (which is where all of our weather occurs), but it extends to over 300 miles above ground.

- C was used to make the first compounds of this group. D is the family member which is present in the largest amount of air. E and F are members of a family containing both gaseous and solid elements. E forms a diatomic molecule and is the major constitute of the atmosphere.

Avogadro's number and the mass of an air molecule A kilogram mole of any gas contains 6 x 1026 molecules. It occupies 22.4 m3 at 0 °C, or about 24 m3 at room temperature, and atmospheric pressure. When students know more about the structure of air (mainly nitrogen and oxygen) then the mass of their atoms can be estimated (they are fairly close in mass).

Air - Molecular Weight and Composition The two most dominant components in dry air are Oxygen and Nitrogen. Oxygen has an atomic unit mass of 16 and Nitrogen has an atomic units mass of 14. Since both of these elements are diatomic in air - O2 and N2, the molecular mass of Oxygen is 32 and the molecular mass of Nitrogen is 28.

- 8 out of 10 atoms (or molecules) of air are made of nitrogen. Nitrogen gas can't be seen but when it is cooled to -320 °F (-195°C) it turns to a liquid, which you can see. Being this cold makes it handy for many things. Shown here, it is being used to quickly freeze cream and sugar to make ice cream.

- A molecule is a particle containing two or more atoms. If it contains only one type of atom it is called an element. An exception to this is diatomic gases (for example: Oxygen, O 2, where the molecule contains two atoms of the same element, bonded covalently.

Atoms, Molecules, and Ions Terms A diatomic molecule is a molecule that contains only two atoms. All of the noninert gases occur as diatomic molecules. Hydrogen, oxygen, nitrogen, fluorine, and chlorine exist as H2, O2, N2, F2, and Cl2, respectively.

- Pure air is a mixture of several gases that are invisible and odourless. It consists of about 78% nitrogen, 21% oxygen, and less than 1% of argon, carbon dioxide, and other gases — as well as varying amounts of water vapour.

- 1 Moist-the air sacs are moist with mucus so that gases can dissolve before diffusing. 2  Large surface area-the surface area for gases to diffuse through in human lungs is roughly the same as a tennis court. 3  Good blood supply-the airsacs have a large capillary network so that large volumes of gases can be exchanged. 4  Page.xygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac. These four features are particularly important to our lungs efficient for gas exchange.

- Ozone is a molecule made up of three atoms of oxygen. It works a lot like sunscreen, blocking out harmful ultraviolet (UV) rays from the sun. In recent years, the amount of ozone in the atmosphere has decreased.

- The Story of Air. 1  The molecule carbon dioxide is made of one carbon atom and two oxygen atoms. 2  Plants don't get carbon from any of these sources. 3  Plants need energy from the sun, water from the soil, and carbon from the air to grow. 4  Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf.

What is a Molecule ? A molecule is the smallest unit (particle) of a compound that has the physical and chemical properties of that compound.

- Since air molecules (oxygen and nitrogen) are small in size, (smaller than wavelengths of visible light), they are more effective at scattering shorter wavelengths (blue and violet) of visible light than the longer wavelengths (red light).

Weird Life: Must Life Be Based on Carbon and Water? 1by John Millam and Ken Klos It's an infinitesimal amount of air when compared to Earth's atmosphere. At sea level on Earth, we breathe in an atmosphere where each cubic centimeter contains 10,000,000,000,000,000,000 molecules; by comparison the lunar atmosphere has less than 1,000,000 molecules in the same volume.

- The measure of the force exerted by air molecules on a surface per unit area is air pressure. 33 people found this useful. Edit. Share to: 1  Four Fates of a Photon When a photon-a tiny particle of light-hits an object, it has four possible fates.he measure of the force due to air pressing on a surface is called the force. If you divide that by the area of the surface, then you have the pressure. 4 people found this useful. Edit.

- Question:Is air heterogeneous or homogeneous and how do you know thanks! Answers:Air is homogeneous. Homogeneous mixtures are mixtures where you can't distinguish any certain parts - so like water, milk, etc. Where as heterogeneous has distinguishable parts - granite, cookie dough ice cream, etc.

- Oxygen and carbon dioxide are two invisible gases in air. The secret to doing this job is BLOOD .The air in your alveoli sends oxygen into your blood. Your blood flows through a system of tubes called blood vessels. First, blood full of oxygen goes to your heart. Your heart is like a big pump.

Air pollution Air pollution is a gas (or a liquid or solid dispersed through ordinary air) released in a big enough quantity to harm the health of people or other animals, kill plants or stop them growing properly, damage or disrupt some other aspect of the environment (such as making buildings crumble), or cause some other kind of nuisance (reduced visibility, perhaps, or an unpleasant odor).

- The element helium is a one-atom molecule. Some molecules consist of two atoms of the same element. For example, O 2 is the oxygen molecule most commonly found in the earth's atmosphere; it has two atoms of oxygen.

How to Calculate Air Density The Gas Constant (R). The gas constant is measure of the weight of the number of molecules of a gas. In the atmosphere around us we have air which is about 78% Nitrogen (N 2) , about 21% Oxygen (O 2) and about 1% other gases. Nitrogen has a molecular weight of 14 so a N 2 molecule has a molecular weight of 28.Oxygen has a molecular weight of 16 so an O 2 molecule has a molecular weight of 32. Given the mixture of gases found in air the average molecular weight of air is around 29.Water is made up of two hydrogen and one oxygen atoms (H 2 O). Hydrogen is the lightest element and has a molecular weight of one.So a water molecule has a molecular weight of 18 (2 * 1 + 1 * 16 = 18). Water is a very light molecule and much lighter than the average weight of the molecules found in air.xygen has a molecular weight of 16 so an O 2 molecule has a molecular weight of 32. Given the mixture of gases found in air the average molecular weight of air is around 29. Water is made up of two hydrogen and one oxygen atoms (H 2 O).

High School Earth Science/The Atmosphere Earth's atmosphere is a thin blanket of gases and tiny particles—together called air. Without air, the Earth would just be another lifeless rock orbiting the Sun. Although we are rarely aware of it, air surrounds us. We are most aware of air when it moves, creating wind.
