Solution

When a reactive metal reacts with dilute hydrochloric acid, metal displaces hydrogen from the acid, leading to evolution of hydrogen gas with the formation of mtal chloride(salt).

Iron reacts with dil. $H_{2} S O_{4} .$ to form iron sulphate with the evolution of hydrogen gas.

Chemical equation:
$F e (s) + H_{2} S O_{4} (a q) \to F e S O_{4} (a q) + H_{2} (g)$
