    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)
