Answer to Question #145420 in General Chemistry for Sania Jafar

Question

correct the underlined statement and name the gas laws connected
1; h2 has the volume of diffusion twice that of o2
2; the volume of gas is expanded twice of its temperature is raised from 27 c to 54 c
1;_4_ times grahm's law 2; _327_ c charle's law

Answer 1

; The rate of diffusion of hydrogen gas is four times faster than oxygen gas.

This is in accordance with Graham's law which states that the rate of effusion or of diffusion of a gas is inversely proportional to the square root of its molecular weight.

2; The volume of a gas is expanded to twice its original volume, this means that the Temperature is doubled.

If the temperature was 27°C (300K) before, it's final Temperature becomes 327°C (600K), which is double 300K.

This is in accordance with Charles's Law.
