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 a reactive metal reacts with dilute hydrochloric acid, the gas produced is hydrogen. The general chemical equation for this type of reaction is:
Metal + 2HCl →Metal chloride+Hydrogen gas
Now, for the specific example of iron reacting with dilute sulfuric acid (H₂SO₄), the chemical equation is as follows:
Fe(s) + H₂SO₄(aq) → FeSO₄(aq) + H₂(g)
In this reaction, iron sulfate (FeSO₄) is formed along with the evolution of hydrogen gas.
Hydrochloric acid when added to a reactive metal like sodium, potassium etc.
Hydrogen gas is evolved.
When iron metal reacts with dilute H2SO4, iron sulphate is formed with the evolution of hydrogen gas.
When reactive metals react with dilute hydrochloric acids, gives a salt and hydrogen gas
Metal + Dilute acid → Salt + Hydrogen
Reaction between Iron and H₂SO₄
