Complete the chemical equations :
`Fe^(2+) + MnO_4^(-) + H^(+) to `

Explanation

To complete the chemical equation for the reaction between \( \text{Fe}^{2+} \), \( \text{MnO}_4^{-} \), and \( \text{H}^{+} \) in acidic medium, we will follow these steps:

### Step 1: Identify the Oxidation and Reduction
In this reaction, \( \text{MnO}_4^{-} \) acts as an oxidizing agent and will oxidize \( \text{Fe}^{2+} \) to \( \text{Fe}^{3+} \). The manganese in \( \text{MnO}_4^{-} \) will be reduced to \( \text{Mn}^{2+} \).

### Step 2: Write the Half-Reactions
1. **Oxidation Half-Reaction**:
\[
