complete net ionic equation?

Explanation / Answer

a) 2K+ (aq) +S2- (aq) + Co2+ (aq) + 2Cl-(aq) --> 2K+ (aq) + 2Cl-(aq) + CoS(s) is total ionic eq

Co2+(aq) + S2-(aq) --> CoS(s) is net ionic

b) 2H+(aq) + SO42-(aq) + CaCO3(s) ---> H2O(l) + CO2(g) + CaSO4(s) is total ionic

2H+ (aq) + SO42-(aq) + CaCO3(s) ---> H2O (l) + CO2(g) + CaSO4(s) is net ionic

c) 2H+ (aq) + 2OCl-(aq) + Ca2+ (aq) + 2OH- (aq) --> 2H2O (l) + Ca2+ (aq) + 2 Ocl-(aq) is total ionic

2H+ (aq) + 2OH-(aq) ---> 2H2O (l) is net ionic
