Zinc replaces copper because zinc is more active than copper. Cu + ZnSO4 No Reaction → Copper cannot replace zinc Oxidation is on top Reduction is on bottom For each reaction below, identify the atom oxidized and the atom reduced, then balance the equation by the method of oxidation-reduction showing all electrons transfers. Mg + HCl MgCl2 + H2 → Fe + V2O3 Fe2O3 + VO → + KNO2 + H2SO4 MnSO4 + H2O + KNO3 + K2SO4 → K2Cr2O7 + SnCl2 + HCl CrCl3 + SnCl4 + KCl + H2O → KMnO4 + NaCl + H2SO4 Cl2 + K2SO4 + MnSO4 + H2O + Na2SO4 →
