$\begin{array}{ccc}{\text{C}}_2{\text{O}}_4^{2-}& ⟶& 2{\text{CO}}_2+2{\text{e}}^{-}]\times 5\\ {\text{MnO}}_4^{-}+8{\text{H}}^{+}+5{\text{e}}^{-}& ⟶& {\text{Mn}}^{2+}+4{\text{H}}_2\text{O}]\times 2\end{array}$
-----------------------------------------------------------------------------------
$\begin{array}{cc}2{\text{MnO}}_4^{-}+16{\text{H}}^{+}+5{\text{C}}_2{\text{O}}_4^{2-}& ⟶\end{array}10{\text{CO}}_2+2{\text{Mn}}^{2+}+8{\text{H}}_2\text{O}$

${\text{MnO}}_4^{-}\Rightarrow \text{x}=2$

${\text{C}}_2{\text{O}}_4^{2-}\Rightarrow \text{y}=5$

${\text{H}}^{+}\Rightarrow \text{z}=16$
