Explanation

Let's solve the question step by step:

### Step 1: Identify the compound of `N, H, and O` that gives laughing gas on heating.
- The compound is **Ammonium Nitrate**.
- **Formula:** NH₄NO₃
- **Explanation:** When Ammonium Nitrate is heated, it decomposes to produce Nitrous Oxide (N₂O), commonly known as laughing gas, along with water.

### Step 2: Identify the compound of `N, H, and O` that gives nitrogen gas on heating.
