When alumina is heated with carbon in the atmosphere of nitrogen then product formed are

Options

A. Al +CO
B. `Al+CO_(2)`
C. `Al+CO+CO_(2)`
D. `AlN+CO`

Answer

To solve the question, we need to analyze the reaction that occurs when alumina (Al₂O₃) is heated with carbon (C) in the presence of nitrogen (N₂).

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are alumina (Al₂O₃) and carbon (C).

2. **Determine the Reaction Conditions**:
- The reaction takes place in an atmosphere of nitrogen (N₂). This is important as nitrogen can influence the products formed.

3. **Write the Chemical Equation**:
- When alumina is heated with carbon, the expected reaction can be represented as:
\[ \text{Al}_2\text{O}_3 + \text{C} \rightarrow \text{Al} + \text{CO} \text{ (in absence of nitrogen)} \]
- However, in the presence of nitrogen, the reaction can lead to the formation of aluminum nitride (AlN) and carbon monoxide (CO).

4. **Balanced Chemical Equation**:
- The balanced equation for the reaction when alumina is heated with carbon in the atmosphere of nitrogen is:
\[ \text{Al}_2\text{O}_3 + 3\text{C} + N_2 \rightarrow 2\text{AlN} + 3\text{CO} \]

5. **Identify the Products**:
- From the balanced equation, the products formed are aluminum nitride (AlN) and carbon monoxide (CO).

6. **Conclusion**:
- Therefore, when alumina is heated with carbon in the atmosphere of nitrogen, the products formed are aluminum nitride (AlN) and carbon monoxide (CO).

### Final Answer:
The products formed when alumina is heated with carbon in the atmosphere of nitrogen are aluminum nitride (AlN) and carbon monoxide (CO).
