Question

Which gas is produced when dilute hydrochloric acid is added to a reactive metal? Write the chemical reaction when iron reacts with dilute H 2 SO 4 .

Answer 1

When a reactive metal reacts with hydrochloric acid hydrogen gas is produced A reactive metal displaces the hydrogen from acid and release hydrogen gas.
Fe(s) .+ dil H2SO4(aq) → FeSO4(aq) + H2(g)

Answer 2

Answer:

hydrogen gas is evolved when the dilute hydrochloric acid added to a reactive metal when iron reacts with dilute H2SO4 the evolution of gas is formed.

its chemical equation is--

Fe(s) + H2SO4(aq) == FeSO4(aq) + H2(g)
