. 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, 4cm3 of hydrogen was left behind. Find the composition of the mixture.
H2 + Cl2 →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 cm3 chlorine.
Therefore, resulting mixture is H2 =4cm3, HCl = 32cm3
