Explanation / Answer

                  CH3OH (aq) + Cr2O72-(aq) ---> CH2O (aq) + Cr3+ (aq)(acidic) Reduction: 6e- +14H+ +Cr2O72- -->2Cr3+ + 7H2O Oxidation: CH3OH --> CH2O +2H+ + 2e-                   3CH3OH --> 3CH2O + 6H+ +6e- Balance:             14H+ + Cr2O72- +3CH3OH --> 3CH2O + 6H+ +2Cr3+ + 7H2O            =>8H+ + Cr2O72- +3CH3OH --> 3CH2O +2Cr3+ + 7H2O
