In each of the following reactions, assign oxidation states to each of the atoms to identify the substance that is oxidized (loses electrons) and the substance that is reduced (gains electrons). a) Cr₂O3 + 2 Al → Al₂O3 + 2 Cr b) 3 H₂+ Fe₂O3 → 2 Fe + 3 H₂O c) 6 Ag + 3 HS- + 2 CrO4+ 5H₂O → 3 Ag₂S + 2 Cr(OH)3 + 7 OH-
