What is the net ionic equation of the ff.:?

Question

1.Ca(NO3)2 (aq) and Na2S(aq)

2.Na3PO4 (aq) and Pb(NO3)2(aq)

3.FeCl3(aq) and NH4NO3(aq)

and can you give me some tips on how to understand and study chemistry?

Answer 1

Ca2+ (aq) + S2- (aq) >> CaS (s)

2 PO43- (aq) + 3 Pb2+ (aq)>> Pb3(PO4)2 (s)

Fe3+ (aq) + 3 OH- (aq) >> Fe(OH)3 (s)
