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

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

When dilute hydrochloric acid is added to a reactive metal, the hydrogen gas is formed.
When dilute hydrochloric acid reacts with a reactive metal (alkali or earth alkali), hydrogen gas is formed.

Reaction of iron (Fe) with dilute sulphuric acid (H₂SO₄₎

Fe(s) + H₂SO₄ (aq) → FeSO₄ (aq) + H₂ ↑(g)

Iron + dil. Sulphuric acid → Ferrous sulphate + Hydrogen gas (released)
