Find `E_(cell)^(@)` for the cell :
`Zn | Zn^(2+)(1M) || Ag^(+)(1M) | Ag`
[Given that : `E_(Zn//Zn^(2+))^(@)=0.76" V" , E_(Ag^(+)//Ag)^(@)=0.80" V"`.

Explanation

To find the standard electromotive force (E_cell^(@)) for the given electrochemical cell, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Half-Reactions**:
- The cell notation is given as: `Zn | Zn^(2+)(1M) || Ag^(+)(1M) | Ag`.
- From this notation, we can identify the oxidation and reduction half-reactions:
- **Anode (oxidation)**: \( \text{Zn} \rightarrow \text{Zn}^{2+} + 2e^- \)
