Question

Which gas is produced when dilute hydrochloric acid is added to a reactive metal? Write the chemical reaction when iron reacts with dilute H2SO4.​

Answer 1

Explanation:

Hydrogen gas is evolved when dilute hydrochloric acid is added to a reactive metal. When iron reacts with dilute H2SO4, iron (II) sulphate with the evolution of hydrogen gas is formed.

Answer 2

When dilute Hydrochloric acid reacts with a reactive metal then hydrogen gas releases with the formation of a metal salt......

for example :-   2HCl (dil.) + 2Na ------ 2NaCl + H2

When Fe(iron) reacts with H2SO4 (sulphuric acid) then hydrogen gas releases with the formation of a iron salt(ferrous sulphate)..

H2SO4 (dil.) + Fe ------------- FeSO4 + H2
