Complete and balance the following equations :
`( c) MnO_(4)^(-) Fe C_(2) O_(4) overset(H^(+)) (to)`

Explanation

To complete and balance the given equation \( \text{MnO}_4^{-} + \text{FeC}_2\text{O}_4 \overset{(H^{+})}{\rightarrow} \) step by step, we will follow the half-reaction method.

### Step 1: Identify Oxidation and Reduction
1. **Oxidation State of Carbon in \( \text{C}_2\text{O}_4^{2-} \)**:
- Let the oxidation state of Carbon be \( x \).
- The equation for the oxidation state is:
\[
2x + 4(-2) = -2 \implies 2x - 8 = -2 \implies 2x = 6 \implies x = +3
