C. `2AgNO_(3) to AgNO_(2) + O_(2)`
D. `2AgNO_(3)to 2Ag + N_(2) + 30_(2)`

Answer

To determine which of the following reactions occurs with ammoniacal AgNO₃ solution, we need to analyze the reactions provided and identify if any of them produce a reaction with ammoniacal silver nitrate.

### Step-by-Step Solution:

1. **Understanding Ammoniacal Silver Nitrate**:
Ammoniacal silver nitrate solution is a solution of silver nitrate (AgNO₃) in ammonia (NH₃). It is known for its ability to react with certain compounds, particularly those that can reduce silver ions (Ag⁺) to metallic silver (Ag).

2. **Analyzing the Reactions**:
- **Reaction 1**: 2AgNO₃ → 2Ag + 2NO₂ + O₂
- **Reaction 2**: AgNO₃ → Ag + NO + O₂
- **Reaction 3**: 2AgNO₃ → AgNO₂ + O₂
- **Reaction 4**: 2AgNO₃ → 2Ag + NO₂ + 3O₂

3. **Identifying the Correct Reaction**:
- **Reaction 1**: This reaction shows the decomposition of silver nitrate when heated above 450°C, producing silver, nitrogen dioxide, and oxygen. This reaction does not directly involve ammoniacal AgNO₃.
- **Reaction 2**: This reaction also shows the decomposition of silver nitrate but does not involve ammoniacal conditions.
- **Reaction 3**: This reaction indicates the formation of silver nitrite (AgNO₂) when heated at temperatures less than 210°C. This reaction does not involve ammoniacal AgNO₃.
- **Reaction 4**: This reaction shows a similar decomposition as Reaction 1 but with different stoichiometry. Again, it does not involve ammoniacal AgNO₃.

4. **Conclusion**:
The first reaction (2AgNO₃ → 2Ag + 2NO₂ + O₂) is the only reaction that is relevant when considering the decomposition of silver nitrate, but it does not specifically indicate a reaction with ammoniacal AgNO₃. However, it is the most significant reaction in terms of the decomposition of AgNO₃.

Thus, the correct answer to the question is **Option 1**.
