(A) The half-reactions are:Reduction: $(MnO_4^- + 8H^{+} + 5e^- \to Mn^{2+} + 4H_2O) \times 2$Oxidation: $(C_2O_4^{2-} \to 2CO_2 + 2e^-) \times 5$Adding the two half-reactions to balance the electrons:$2MnO_4^- + 16H^{+} + 10e^- + 5C_2O_4^{2-} \to 2Mn^{2+} + 8H_2O + 10CO_2 + 10e^-$The balanced equation is:$2MnO_4^- + 5C_2O_4^{2-} + 16H^{+} \to 2Mn^{2+} + 10CO_2 + 8H_2O$Thus,the coefficients of $MnO_4^-$,$C_2O_4^{2-}$,and $H^{+}$ are $2, 5$,and $16$ respectively.
