Ammonium nitrate on heating gives

Options

A. `NO`
B. `N_(2)`
C. `N_(2)O`
D. `N_(2)O_(4)`

Answer

To solve the question "Ammonium nitrate on heating gives," we will follow these steps:

### Step-by-Step Solution:

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

2. **Understand the Process**:
- When ammonium nitrate is heated, it undergoes thermal decomposition.

3. **Write the Decomposition Reaction**:
- The decomposition of ammonium nitrate can be represented as:
\[ NH_4NO_3 \rightarrow N_2O + H_2O \]
- Here, nitrous oxide (\( N_2O \)) and water vapor (\( H_2O \)) are produced.

4. **Balance the Reaction**:
- To balance the reaction, we can multiply the reactants and products appropriately. The balanced equation is:
\[ 2NH_4NO_3 \rightarrow N_2O + 2H_2O \]

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

6. **Conclusion**:
- Therefore, the primary product of heating ammonium nitrate is nitrous oxide, which is also known as laughing gas.

### Final Answer:
Ammonium nitrate on heating gives nitrous oxide (\( N_2O \)) and water vapor (\( H_2O \)).
