Calculate the n-factor of reactants in the given chemical changes
(c ) `NO_(3)^(-)rarrN_(2)O`

Explanation

To calculate the n-factor of the reactant in the given chemical change \( \text{NO}_3^- \rightarrow \text{N}_2\text{O} \), we will follow these steps:

### Step 1: Identify the oxidation states
- In the reactant \( \text{NO}_3^- \), nitrogen (N) has an oxidation state of +5.
- In the product \( \text{N}_2\text{O} \), we need to determine the oxidation state of nitrogen. In \( \text{N}_2\text{O} \), the oxidation state of nitrogen can be calculated as follows:
- Let the oxidation state of nitrogen be \( x \).
- The oxidation state of oxygen (O) is -2.
- The equation for the compound is:
