Use electron or electron shift to identify what element is oxidized and what element is reduced in each reaction. NOTE: "Element" does NOT mean molecule, just the atom, please!For the same reactions, what are the oxidizing agent and what are the reducing agents? (NOTE: Molecules)a. 2 Na(s) + Br2(l) ---> 2 NaBr(s)b. H2(g) + Cl2(g) ---> 2 HCl(g)c. 2 Li(s) + F2(g) ---> 2 NiF(s)d. S(s) + Cl2(g) ---> SCl2(g)e. N2(g) + 2 O2(g) ---> 2 NO2(g)f. Mg(s) + Cu(NO3)2(aq) ---> Mg(NO3)2(aq) + Cu(s)
