Can you please help me write the oxidation and reduction half reactions represented in each of these redox equations, and help me write the half reactions in net ionic form if they occur in aqueous solution.

Question

1) PbO(s) + NH3(g) --> N2(g) + H2O(l) + Pb(s)
2) I2(s) + Na2S2O3(aq) --> Na2S2O4(aq) + NaI(aq)
3) Sn(s) +2HCl(aq) --> SnCl2(aq) + H2(g)
