For the following reactions please write the a) molecular equation b) the total ionic equation c) the net ionic equation?

1.
a) FeI₂(aq) + Ca(OH)₂(aq) → Fe(OH)₂(s) + CaI₂(aq)
b) Fe²⁺(aq) + 2I⁻(aq) + Ca²⁺(aq) + 2OH⁻(aq) → Fe(OH)₂(s) + Ca²⁺(aq) + 2I⁻(aq)
b) Fe²⁺(aq) + 2OH⁻(aq) → Fe(OH)₂(s)

2.
a) Ag₂CO₃(s) + 2HNO₃(aq) → 2AgNO₃(aq) + H₂O(l) + CO₂(g)
b) Ag₂CO₃(s) + 2H⁺(aq) + 2NO₃⁻(aq) → 2Ag⁺(aq) + 2NO₃⁻(aq) + H₂O(l) + CO₂(g)
c) Ag₂CO₃(s) + 2H⁺(aq) → 2Ag⁺(aq) + H₂O(l) + CO₂(g)

3.
There are no reaction, and thus there is no equation.

4.
a) H₂SO₃(aq) + 2NaOH(aq) → Na₂SO₃(aq) + 2H₂O(l)
b) 2H⁺(aq) + SO₃²⁻(aq) + 2Na⁺(aq) + 2OH⁻(aq) → 2Na⁺(aq) + SO₃²⁻(aq) + 2H₂O(l)
c) H⁺(aq) + OH⁻(aq) → H₂O(l)
