Justify that the following reactions are redox reactions :
`4NH_(3)(g)+5O_(2)(g)to4NO(g)+6H_(2)O(g)`

Explanation

To justify that the reaction `4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(g)` is a redox reaction, we will follow these steps:

### Step 1: Identify Oxidation States
We need to assign oxidation states to each element in the reactants and products.

- **In Ammonia (NH₃):**
- Hydrogen (H) has an oxidation state of +1.
- Nitrogen (N) has an oxidation state of -3 (since there are three +1 from H, the total must equal 0).
