The air in your room is composed mostly ofoxygen 1O22 and nitrogen 1N22 molecules. The oxygen moleculesare more massive than the nitrogen molecules. (a) Is the rms speedof the O2 molecules greater than, less than, or equal to the rmsspeed of the N2 molecules? (b) Choose the best explanation fromamong the following:I. The more massive oxygen molecules have greater momentumand therefore greater speed.II. Equal temperatures for the oxygen and nitrogen moleculesimply they have equal rms speeds.III. The temperature is the same for both molecules, and hencetheir average kinetic energies are equal. As a result, the moremassive oxygen molecules have lower speeds

Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.
