Calculate the number of coulombs delivered by a Daniel cell, initially containing 1 litre each of 1M `Cu^(2+) and 1M Zn^(2+)` ion which is operated until its potential drops to 1V.
`E_(Cu^(2+),Cu)^@=0.34V, E_(Zn^(2+),Zn)^@=-0.76V`

To solve the problem of calculating the number of coulombs delivered by a Daniel cell, we will follow these steps: ### Step 1: Identify the half-reactions and the overall cell reaction In a Daniel cell, the oxidation and reduction half-reactions are as follows: - **Oxidation (Anode)**: Zinc is oxidized to zinc ions. \[ \text{Zn (s)} \rightarrow \text{Zn}^{2+} (aq) + 2e^- \] ...
