Net Ionic Reactions

What is the "molecular equation" for the reaction of NaCl and Pb(NO3)2?
NaCl + Pb(NO3)2 → Na(NO3)2 + PbCl
NaCl + Pb(NO3)2 → NaNO3 + PbCl2
2 NaCl + Pb(NO3)2 → 2 NaNO3 + PbCl2
No reaction

What is the "net ionic" for the reaction of NaCl and Pb(NO3)2?
Na+(aq) + NO3-(aq) → NaNO3(s)
Pb2+(aq) + 2 Cl-(aq) → PbCl2(s)
Pb2+(aq) + 2 Na+(aq) → PbNa2(s)
No reaction

What are the spectator ions for the reaction of NaCl and Pb(NO3)2?
Na+ and NO3-
Pb2+ and Cl-
Only Na+
There are no spectator ions

What is the net ionic reaction for the reaction of Ba(NO3)2 + NaCl?
