Write word equations and then balanced equations for the reaction taking place when
(a) Dilute sulphuric acid reacts with zinc granules.
(b) Dilute hydrochloric acid reacts with magnesium ribbon.
(c) Dilute sulphuric acid reacts with aluminium powder.
(d) Dilute hydrochloric acid reacts with iron filings.

(a) Dilute sulphuric acid reacts with zinc granules to give zinc sulphate and hydrogen gas
Dilute sulphuric acid + zinc → Zinc Sulphate + Hydrogen Gas
H₂SO₄(aq) + Zn → ZnSO₄(aq) + H₂(g)

(b) Dilute hydrochloric acid reacts with magnesium ribbon to give magnesium oxide and hydrogen gas.
Dilute Hydrochloric + Magnesium → Magnesium Chloride + Hydrogen Gas

2HCl(aq) + Mg → MgCl₂(aq) + H₂(g)

(c) Dilute sulphuric acid reacts with aluminium powder to produce Aluminium Sulphate and Hydrogen Gas
Dilute Sulphuric Acid + Aluminium → Aluminium Sulphate + Hydrogen Gas

3H₂SO₄(aq) + 2Al(s) → Al₂(SO₄)₃(aq) + 3H₂(g)

(d) Dilute hydrochloric acid reacts with iron filings to produce Ferrous Chloride and Hydrogen Gas.

Dilute Hydrochloric Acid + Iron → Ferrous Chloride + Hydrogen Gas

6HCl(aq) + 3Fe(s) → 3FeCl₂(aq) + 3H₂(g)
