Chemistry: Ionic and Net Ionic Reactions

The ionic equation lists all the ions involved and the net ionic equation only lists the spectator ions.

BaCl2 + Na2SO4 = BaSO4 + 2NaCl
Pb(NO3)2 + KCl = PbCl2 + KNO3
2AgNO3 + Na2CO3 = Ag2CO3 + 2NaNO3
NaOH + Fe(ClO4)3 = NaClO4 + Fe(OH)2
CaCl2 + Na2SO4 = CaSO4 + 2NaCl
K2S + Ni(NO3) = 2KNO3 + NiS
