Calculate the n- factor of reactants in the given chemical changes?
(b ) `C_(2)O_(4)^(2-)rarrCO_(2)`

Explanation

To calculate the n-factor of the reactants in the given chemical change \( C_2O_4^{2-} \rightarrow CO_2 \), we will follow these steps:

### Step 1: Identify the oxidation states
First, we need to determine the oxidation states of carbon in both the reactant and product.

- In \( C_2O_4^{2-} \):
- Oxygen (O) has an oxidation state of -2.
- Let the oxidation state of carbon (C) be \( x \).
