Which of the following gases diffuse more slowly than oxygen? F2, Ne, N2O, C2H2, NO, Cl2, H2S

Cl2, N2O, F2, H2S

Explanation:

You must recall Graham's law at this point. Graham's law states that the rate of diffusion of a gas is inversely proportional to the square root of its vapour density or molar mass.

Now, the greater the molar mass of a gas, the lesser the rate of diffusion of that gas. The gas that will diffuse more slowly than oxygen must have a higher molar mass than oxygen. Oxygen has a molar mass of 32gmol-1, let us look at the molar masses of other gases.

F2= 37.99681 g/mol

Ne= 20.1797 gmol-1

N2O= 44.013 g/mol

C2H2= 26.04 g/mol

NO= 30.01 g/mol

Cl2= 70.906 gmol-1

H2S= 34.1 g/mol

Hence in order of decreasing slower diffusion than oxygen gas

Cl2, N2O, F2, H2S

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.
