Write balanced complete ionic equation and a balanced net ionic equation for the following: Express your answer as a chemical equation. Identify all of the phases in your answer.
1) K2SO4(aq) + CaI2(aq) --> CaSO4(s) + KI(aq)
2) NH4Cl(aq) + NaOH(aq) --> H2O(l) + NH3 (g) + NaCl(aq)
3) AgNO3(aq) + NaCl(aq) --> AgCl(s) + NaNO3(aq)
4) HC2H3O2(aq) + K2CO3(aq) --> H2O(l) + CO2(g) + KC2H3O2(aq)
