Which of the following combination does not liberated `NH_(3)` gas?

Options

A. Heating of `NH_(4)ClO_(4)`
B. Heating of `NH_(4)Cl`
C. `(NH_(4))_(2)CO_(30+NaOH`
D. `Li_(3)N+H_(2)O`

Explanation

To determine which combination does not liberate ammonia gas (NH₃), we will analyze each reaction provided in the question step by step.

### Step 1: Analyze the first reaction - Heating of NH₄ClO₄
- **Reaction**: NH₄ClO₄ (ammonium perchlorate) is heated.
- **Products**: The decomposition of ammonium perchlorate produces nitrogen gas (N₂), oxygen gas (O₂), chlorine gas (Cl₂), and water (H₂O).
- **Conclusion**: This reaction does not produce ammonia gas (NH₃).

### Step 2: Analyze the second reaction - Heating of NH₄Cl
- **Reaction**: NH₄Cl (ammonium chloride) is heated.
- **Products**: This reaction decomposes to form ammonia gas (NH₃) and hydrochloric acid (HCl).
- **Conclusion**: This reaction liberates ammonia gas (NH₃).

### Step 3: Analyze the third reaction - NH₄CO₃ with NaOH
- **Reaction**: NH₄CO₃ (ammonium carbonate) reacts with NaOH (sodium hydroxide).
- **Products**: The reaction produces ammonia gas (NH₃), sodium carbonate (Na₂CO₃), and water (H₂O).
- **Conclusion**: This reaction liberates ammonia gas (NH₃).

### Step 4: Analyze the fourth reaction - Li₃N with water
- **Reaction**: Li₃N (lithium nitride) reacts with water.
- **Products**: This reaction produces lithium hydroxide (LiOH) and ammonia gas (NH₃).
- **Conclusion**: This reaction liberates ammonia gas (NH₃).

### Final Conclusion
Among the reactions analyzed, the only reaction that does not liberate ammonia gas is the heating of ammonium perchlorate (NH₄ClO₄). Therefore, the correct answer to the question is:

**Answer**: Heating of NH₄ClO₄ does not liberate NH₃ gas.
