  1. You add the aq and l and s.
    Molecular equation:
    Na2CO3 + NiCl2 ==> 2NaCl + NiCO3(s)

    Total ionic equation:
    2Na^+ + CO3^2- + Ni^2+ + 2Cl^- ==> 2Na^+ + 2Cl^- + NiCO3(s)

    Net ionic equation: Just cancel the ions that are common to both sides. What left is the net ionic equation.
    CP3^2-(aq) + Ni^2+(aq) ==> NiCO3(s)

    Do the same for the other one.
