Justify that the following reactions are redox reactions :
`Fe_(2)O_(3)(s)+3CO(g)to2Fe(s)+3CO_(2)(g)`

Explanation

To justify that the reaction `Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)` is a redox reaction, we need to analyze the oxidation states of the elements involved in the reaction. Here’s a step-by-step breakdown:

### Step 1: Identify the Reactants and Products
The reactants are iron(III) oxide (Fe₂O₃) and carbon monoxide (CO). The products are iron (Fe) and carbon dioxide (CO₂).

### Step 2: Assign Oxidation States
- **For Fe₂O₃:**
- Oxygen (O) has an oxidation state of -2.
