In these equations, figure out which atom loses electrons and which atom gains the electrons. Use net ionic equations when possible.

a. Mg(s) + Cu(NO3)2(aq) ---> Mg(NO3 )2(aq) + Cu(s)

b. Cl2(g) + S(s) ---> SCl2(g)

c. CuO(s) + H2(g) ---> Cu(s) + H2O(l)

d. 2 PbS(s) + 3 O2 ---> 2 PbO(s) + 2 SO2(g)

e. 6 Li(s) + N2(g) ---> 2Li3N(s)

f. 3 CuCl2(aq) + 2 Al(s) ---> 2 AlCl3(aq) + 3 Cu(s)
