Producer gas is a mixture of

Options

A. carbon monoxide and nitrogen gas
B. carbon monoxide and hydrogen gas
C. carbon monoxide and water vapour
D. carbon monoxide and nitrous oxide

Explanation

**Step-by-Step Solution:**

1. **Understanding Producer Gas**: Producer gas is a type of gas that is generated from the gasification of carbonaceous materials, typically coal or coke, in the presence of limited air.

2. **Chemical Reaction**: The formation of producer gas involves a reaction between coke (carbon) and air. The relevant chemical reaction can be simplified as:
\[ \text{C (coke)} + \text{O}_2 \rightarrow \text{CO (carbon monoxide)} + \text{N}_2 \text{ (nitrogen gas)} \]
Here, carbon reacts with oxygen to produce carbon monoxide and nitrogen gas.

3. **Components of Producer Gas**: From the reaction, we can see that the primary components of producer gas are:
- Carbon monoxide (CO)
- Nitrogen gas (N₂)

4. **Conclusion**: Therefore, producer gas is a mixture of carbon monoxide (CO) and nitrogen gas (N₂).

5. **Final Answer**: The correct answer is that producer gas is a mixture of carbon monoxide (CO) and nitrogen gas (N₂).
