Use electron transfer or electron shift to identify what is oxidized and what is reduced in each reaction :

A2Na(s) + Br2(l) ----> 2NaBr(s)

BH2(g) + Cl2(g) ----> 2HCl(g)

C2Li(s) + F2(g) ----> 2LiF(s)

DS(s) + Cl2(g) ----> SCl2(g)

e)N2(g) + 2O2(g) ----> 2NO2(g)

f) Mg(s) +Cu(NO3)2(aq) = Mg(NO3)2(aq) + Cu(s)


For each reaction above, identify the reducing agent and the oxidizing agent
