Answer 2

(a) Na + H₂O ⟶ NaOH + H₂

Balanced chemical equation : 2Na + 2H₂O ⟶ 2NaOH + H₂

(b) Ca + H₂O ⟶ Ca(OH)₂ + H₂

Balanced chemical equation : Ca + 2H₂O ⟶ Ca(OH)₂ + H₂

(c) Mg + H₂O ⟶ Mg(OH)₂ + H₂

Balanced chemical equation : Mg + 2H₂O ⟶ Mg(OH)₂ + H₂

(d) Zn + H₂O ⟶ Zn(OH)₂ + H₂

Balanced chemical equation : Zn + 2H₂O ⟶ Zn(OH)₂ + H₂

(e) Fe + H₂O ⟶ Fe₃O₄ + H₂

Balanced chemical equation : 3Fe + 4H₂O ⟶ Fe₃O₄ + 4H₂

(f) Zn + HCl ⟶ ZnCl₂ + H₂

Balanced chemical equation : Zn + 2HCl ⟶ ZnCl₂ + H₂

(g) Al + H₂SO₄ ⟶ Al₂(SO₄)₃ + H₂

Balanced chemical equation : 2Al + 3H₂SO₄ ⟶ Al₂(SO₄)₃ + 3H₂  

(h) Fe + HCl ⟶ FeCl₂ + H₂

Balanced chemical equation : Fe + 2HCl ⟶ FeCl₂ + H₂

(i) Zn + NaOH ⟶ Na₂ZnO₂ + H₂

Balanced chemical equation : Zn + 2NaOH ⟶ Na₂ZnO₂ + H₂  

(j) Al + KOH + H₂O ⟶ K[Al(OH)₄] + H₂

Balanced chemical equation : 2Al + 2KOH + 6H₂O ⟶ 2K[Al(OH)₄] + 3H₂
