Write the balanced equation for the following chemical reactions.

Explanation:

A balanced chemical equation has charge and mass same on both sides of a chemical reaction. Also, the physical states of the reactants and products are clearly mentioned.

(i) H₂ (g) + Cl₂ (g) → 2HCl (g)

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

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

Final Answer:

(i) H₂ (g) + Cl₂ (g) → 2HCl (g)

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

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