When dilute hydrochloric acid is added to a reactive metal, hydrogen gas is produced. This is because the acid reacts with the metal to form a salt and hydrogen gas. The general chemical equation for this reaction is: Metal + Dilute acid → Salt + Hydrogen.
When iron reacts with dilute sulfuric acid (H2SO4), iron sulfate (FeSO4) and hydrogen gas (H2) are produced. The chemical equation for this reaction is: Fe + H2SO4 → FeSO4 + H2.
