### VOLTAIC CELL NOTATION
#### 19.41
Write the cell notation for a voltaic cell with the following conditions.
#### 19.39
Describe a voltaic cell using this reaction. What are the half-reactions?
\[ \text{Zn(s)} + 2\text{Ag}^+ (\text{aq}) \rightarrow \text{Zn}^{2+} (\text{aq}) + 2\text{Ag} (\text{s}) \]
#### 19.40
Obtain half-reactions and describe a silver oxide-zinc cell that maintains a fairly constant voltage during discharge (1.60 V). This cell is used in watches, hearing aids, and other electronic devices. The half-reactions are:
\[ \text{Zn(s)} + 2\text{OH}^- (\text{aq}) \rightarrow \text{Zn(OH)}_2 (\text{s}) + 2\text{e}^- \]
\[ \text{Ag}_2\text{O(s)} + \text{H}_2\text{O(l)} + 2\text{e}^- \rightarrow 2\text{Ag(s)} + 2\text{OH}^- (\text{aq}) \]
Identify the anode and the cathode reactions. What is the overall reaction in the voltaic cell?
