For the redox reaction,

${\mathrm{MnO}}_4^{-}+{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+{\mathrm{H}}^{+}\to {\mathrm{Mn}}^{2+}+{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}$

The correct coefficients of the reactants for the balanced equation are

• A

  $16{\mathrm{MnO}}_4^{-} +5{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+2 {\mathrm{H}}^{+}$

• B

  $2{\mathrm{MnO}}_4^{-}+5{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+16 {\mathrm{H}}^{+}$

• C

  $2{\mathrm{MnO}}_4^{-}+16{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+5 {\mathrm{H}}^{+}$

• D

  $5{\mathrm{MnO}}_4^{-}+16{\mathrm{C}}_2{\mathrm{O}}_4^{2-}+2 {\mathrm{H}}^{+}$
