Write the half equations for each of the following redox reactions.
`NO_(3)^(-)+ZntoZn^(2+)+NH_(3)^(+)`

Explanation

To write the half equations for the given redox reaction \( \text{NO}_3^- + \text{Zn} \rightarrow \text{Zn}^{2+} + \text{NH}_3^+ \), we need to identify the oxidation and reduction processes involved.

### Step 1: Identify Oxidation and Reduction
- **Oxidation** is the loss of electrons, and in this reaction, zinc (Zn) is oxidized from its elemental state (0) to zinc ions (\( \text{Zn}^{2+} \)).
- **Reduction** is the gain of electrons, and nitrogen in \( \text{NO}_3^- \) is reduced to ammonia (\( \text{NH}_3^+ \)).

### Step 2: Write the Oxidation Half-Reaction
The oxidation half-reaction involves zinc losing two electrons:
