Balance the following half cell reactions.
`MnO_(4)^(-)toMn^(2+)`

Explanation

To balance the half-cell reaction \( \text{MnO}_4^{-} \rightarrow \text{Mn}^{2+} \), we will follow these steps:

### Step 1: Write the unbalanced half-reaction
The unbalanced half-reaction is:
\[ \text{MnO}_4^{-} \rightarrow \text{Mn}^{2+} \]

### Step 2: Balance the manganese atoms
There is one manganese atom on both sides, so manganese is already balanced.
