    1.

    YES

    K2SO4 (aq) + Ba (NO3) 2 (aq) - -> Ba (SO4) 2 (s) + 2KNO3 (aq)

    Net ionic equation

    2SO4^2 - (aq) + Ba2 + (aq) - -> Ba (SO4) 2 (s)

    2.

    NO

    No precipitate is formed because KNO3, MgSO4, K2SO4 and Mg (NO3) 2 all are soluble.

    3.

    YES

    BaCl2 (aq) + Na2 (SO4) (aq) - -> BaSO4 (s) + 2NaCl (aq)

    Net ionic equation:

    Ba2 + (aq) + SO4^2 - (aq) - -> BaSO4 (aq)

    4.

    Ni2 + (aq) + S2 - (aq) - --> NiS (s)
