Nitrolim is a mixture of carbon and

Explanation

To solve the question about what Nitrolim is a mixture of, we can follow these steps:

### Step-by-Step Solution:

1. **Identify Nitrolim**:
- Nitrolim is known to be a nitrogenous fertilizer.

2. **Understand its Formation**:
- Nitrolim is formed by the reaction of nitrogen gas with calcium carbide.

3. **Write the Reaction**:
- The chemical reaction can be represented as:
\[ \text{CaC}_2 + \text{N}_2 \rightarrow \text{CaCN}_2 + \text{C} \]
- In this reaction, calcium carbide (CaC₂) reacts with nitrogen gas (N₂) to produce calcium cyanamide (CaCN₂) and carbon (C), specifically in the form of graphite.

4. **Identify the Components**:
- From the reaction, we can see that the products are calcium cyanamide (CaCN₂) and carbon (C).

5. **Conclusion**:
- Therefore, Nitrolim is a mixture of carbon and calcium cyanamide (CaCN₂).

### Final Answer:
Nitrolim is a mixture of carbon and calcium cyanamide (CaCN₂).
