The standard reduction potential for `Zn^(2+)//Zn` is -0.76V. Write the reactions occurring at the electrodes when coupled with NHE or SHE.

Explanation

To solve the problem, we need to identify the reactions occurring at the electrodes when zinc (Zn) is coupled with the Standard Hydrogen Electrode (SHE), which has a standard reduction potential of 0 V.

### Step-by-Step Solution:

1. **Identify the Reduction Reaction for Zinc:**
The standard reduction potential for the reaction \( \text{Zn}^{2+} + 2e^- \rightarrow \text{Zn} \) is given as -0.76 V. This indicates that zinc ions can be reduced to zinc metal.

2. **Identify the Reaction for the Standard Hydrogen Electrode (SHE):**
