1.
Full balanced equation:
BaCl₂(aq) + MgSO₄(aq) → BaSO₄(s) + MgCl₂(aq)

Full ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + Mg²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s) + Mg²⁺(aq) + 2Cl⁻(aq)

Net ionic equation:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)

2.
Full balanced equation:
K₂S(aq) + CdCl₂(aq) → CdS(s) + 2KCl(aq)

Full ionic equation:
2K⁺(aq) + S²⁻(aq) + Cd²⁺(aq) + 2Cl⁻(aq) → CdS(s) + 2K⁺(aq) + 2Cl⁻(aq)

Net ionic equation:
Cd²⁺(aq) + S²⁻(aq) → CdS(s)
