Question

Write the balanced equation for the following chemical reactions.

(i) Hydrogen + Chlorine → Hydrogen chloride
(ii) Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride
(iii) Sodium + Water → Sodium hydroxide + Hydrogen

Answer 1

(i) H₂ (g) + Cl₂ (g) → 2HCl (g)

(ii) 3BaCl₂ (s) + Al₂(SO₄)₃ (s) → 3BaSO₄ (s) + 2AlCl₃ (s)

(iii) 2Na(s) + 2H₂O (l) → 2NaOH (aq) + H₂ (g)
