Question

The hydrogen halide gases all have the same general formula, HX, where X can be a halogen (F, CI, Br, or I). HCl 2 effuses times faster than one of the others, which one is it; HF, HBr or HI?

Answer 1

Answer:

Explanation:

We collected the gas over water; to obtain the true pressure of the gas, we have to correct for the vapor pressure of water. We look up the vapor pressure of water at 24 ºC: 24 torr. The pressure of the evolved gas is, therefore, 738 −24 = 714 torr. 2. We want the molar mass of the

Answer 2

HF effuses two times faster than HI according to Graham's law.

What is effusion?

The term effusion menas the ability of a gas to escape through an oriffice. This ability hugely depends on the molecular weight of the gas. The smaller the molecular weight, the higher the rate of effusion.

Considering the molecular weight of HCl and HI we can conclude that HF effuses two times faster than HI according to Graham's law.
