उत्तर
\[\ce{H2 + Cl2 -> 2HCl}\]
1 vol. : 1 vol. → 2 vol.
As 4 cm3 of hydrogen was left behind, hence, 36 − 4 = 32 cm3 of a mixture of hydrogen and chlorine exploded.
As, 1 Vol. of hydrogen requires 1 Vol. of oxygen
∴ 16 cm3 hydrogen requires 16 cm3 of oxygen
∴ Mixture is 20 cm3 (i.e., 16 + 4) of hydrogen and 16 cm3 of chlorine.

Calcium carbide is used for the artificial ripening of fruits. Actually the fruit ripens because of the heat evolved while calcium carbide reacts with the moisture. During this reaction calcium hydroxide and acetylene gas are formed.
