Find the standard electrode potential of `MnO_(4)^(c-)|MnO_(2).` The standard electrode potential of `MnO_(4)^(c-)|Mn^(2+)=1.51V` and `MnO_(2)|MnO_(2)|Mn^(2+)=1.23V`.

Explanation

To find the standard electrode potential of the half-reaction \( \text{MnO}_4^- \) to \( \text{MnO}_2 \), we can use the given standard electrode potentials for the reactions involving \( \text{MnO}_4^- \) to \( \text{Mn}^{2+} \) and \( \text{MnO}_2 \) to \( \text{Mn}^{2+} \).

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Standard electrode potential for \( \text{MnO}_4^- \) to \( \text{Mn}^{2+} \): \( E^\circ_1 = 1.51 \, \text{V} \)
- Standard electrode potential for \( \text{MnO}_2 \) to \( \text{Mn}^{2+} \): \( E^\circ_2 = 1.23 \, \text{V} \)
