The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham’s Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium.

Diffusion is fastest through gases, followed by liquid, then plasma, and lastly, solids. In chemistry, diffusion is defined as the movement of matter by the random motions of molecules.

It states that the diffusion rate of a gas is inversely proportional to the square root of its molar mass (molecular weight). Stated in simpler terms, lighter gases (in terms of density or molecular weight) will diffuse faster than those gases with higher densities or molecular weight.

Nitrogen oxygen

In the presence of very high temperatures nitrogen and oxygen do react together to form nitric oxide. These conditions are found in the combustion of coal and oil at electric power plants, and also during the combustion of gasoline in automobiles.

Sodium acetate

The chemical name for HC2H3O2 is acetic acid.

Is sodium sulfite an acid or a base? Sodium sulphite, Na2SO3, is a salt made from the neutralization reaction between a strong base (sodium hydroxide) and a weak acid (sulphurous acid). Its aqueous solution is, therefore, distinctly basic in nature, with a pH value slightly greater than 7.
