Ammonium nitrate decomposes on heating into

Options

A. Ammonia and nitric acid
B. Nitrous oxide and water
C. Nitrogen, hydrogne and ozone
D. Nitric oxide, nitrogen dioxide
and hydrogen

Explanation

To solve the question about the decomposition of ammonium nitrate upon heating, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Chemical Formula**:
- Ammonium nitrate is represented by the chemical formula \( NH_4NO_3 \).

2. **Understand the Decomposition Reaction**:
- When ammonium nitrate is heated, it undergoes decomposition. The general form of the decomposition reaction needs to be determined.

3. **Write the Decomposition Equation**:
- The decomposition of ammonium nitrate can be represented as:
\[ NH_4NO_3 \rightarrow N_2O + 2H_2O \]
- Here, \( N_2O \) is nitrous oxide (also known as laughing gas), and \( H_2O \) is water.

4. **Balance the Reaction**:
- The reaction is balanced as written, with 1 molecule of ammonium nitrate producing 1 molecule of nitrous oxide and 2 molecules of water.

5. **Identify the Products**:
- From the balanced equation, we can see that the products of the decomposition of ammonium nitrate are nitrous oxide (\( N_2O \)) and water (\( H_2O \)).

6. **Choose the Correct Option**:
- Based on the products identified, the correct answer to the question is that ammonium nitrate decomposes on heating into nitrous oxide and water.

### Final Answer
Ammonium nitrate decomposes on heating into nitrous oxide (\( N_2O \)) and water (\( H_2O \)).
