Give balanced equations for the preparation of the following salts:1.

1.	Give balanced equations for the preparation of the following salts:1. Calcium oxide → Calcium chloride → Calcium carbonate2. Zinc sulphide Zn→ Zinc sulphate3. Iron (II) chloride ← Fe→ Iron (III) chloride4. Lead (II) oxide → Lead nitrate→ Lead sulphate5. Copper (II) oxide → Copper (II) sulphate ←Copper (II)hydroxide
Answer» 1. CaO + 2HCl → CaCl₂ + H₂O 2. Zn + S → ZnS 3. Fe + 2HCl → FeCl₂ + H₂ 4. PbO + 2HNO₃ → Pb(NO₃)₂ + H₂O 5. CuO + H₂SO₄ → CuSO₄+ H₂O
