(C) The half-equations of the reaction are:$MnO_4^{-} ightarrow Mn^{2+}$$C_2O_4^{2-} ightarrow CO_2$The balanced half-equations are:$(MnO_4^{-} + 8H^{+} + 5e^{-} ightarrow Mn^{2+} + 4H_2O) 	imes 2$$(C_2O_4^{2-} ightarrow 2CO_2 + 2e^{-}) 	imes 5$Equating the number of electrons,we get:$2MnO_4^{-} + 16H^{+} + 10e^{-} ightarrow 2Mn^{2+} + 8H_2O$$5C_2O_4^{2-} ightarrow 10CO_2 + 10e^{-}$On adding both the equations,we get:$2MnO_4^{-} + 5C_2O_4^{2-} + 16H^{+} ightarrow 2Mn^{2+} + 10CO_2 + 8H_2O$Thus,the values of $x, y$ and $z$ are $2, 5$ and $16,$ respectively.
