For the redox recation
`MnO_(4)^(-)+C_(2)O_(4)^(2-)+H^(+)toMn^(2+)+CO_(2)+H_(2)O`
the correct coefficients of the reactants for the blalanced equation are

A

`MnO_(4)^(ө)=2, C_(2)O_(4)^(2-)=5, H^(o+)=16`

B

`MnO_(4)^(ө)=16, C_(2)O_(4)^(2-)=5, H^(o+)=2`

C

`MnO_(4)^(ө)=5, C_(2)O_(4)^(2-)=16, H^(o+)=2`

D

`MnO_(4)^(ө)=2, C_(2)O_(4)^(2-)=16, H^(o+)=5`

Text Solution

Verified by Experts

The correct Answer is:
A
The balanced equation is
`2MnO_(4)^(ө)+5C_(2)O_(4)^(2-)+16H^(o+)rarr2Mn^(2+)+10CO_(2)+8H_(2)O`
