Solution

Hydrogen gas is evolved when dilute hydrochloric acid is added to a reactive metal.

When iron reacts with dilute $H_{2} {SO}_{4}$ , iron (II) sulphate is formed along with the evolution of hydrogen gas. The reaction involved is:

$Fe (s) + H_{2} {SO}_{4} (aq) \to {FeSO}_{4} (aq) + H_{2} (g)$
