. A mixture of hydrogen and chlorine occupying 36 cm3 was exploded


A mixture of hydrogen and chlorine occupying 36 cm3 was exploded. On shaking it with water, 4cmof hydrogen was left behind. Find the composition of the mixture.

 

Best Answer

H2 + Cl→2HCl

1V 1V 2 V

Since 1 V hydrogen requires 1 V of oxygen and 4cm3 of H2 remained behind so the mixture had composition: 16 cm3 hydrogen and 16 cmchlorine.

Therefore, resulting mixture is H2 =4cm3, HCl = 32cm3
