Calculate the n- factor of reactants in the given chemical changes?
(c ) `S_(2)O_(3)^(2-) overset("alkaline")rarrSO_(4)^(2-)`

Explanation

To calculate the n-factor of the reactants in the given chemical change, we will follow these steps:

### Step 1: Write the balanced chemical equation
The given reaction is:
\[ \text{S}_2\text{O}_3^{2-} \xrightarrow{\text{alkaline}} \text{SO}_4^{2-} \]

### Step 2: Determine the oxidation states of sulfur in the reactants and products
1. In \(\text{S}_2\text{O}_3^{2-}\):
