When air is passed through red hot coke, a gaseous fuel is produced. The name of this gaseous fuel and its composition are respectively

Options

A. Natural gas, `CO + H_2`
B. Producer gas, `N_2 + CO`
C. Water gas, `H_2+CO`
D. None of these

Explanation

To solve the question regarding the gaseous fuel produced when air is passed through red hot coke, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are red hot coke (which is primarily carbon) and air (which contains oxygen and nitrogen).

2. **Understand the Reaction**:
- When red hot coke is exposed to air, the carbon in the coke reacts with the oxygen in the air.

3. **Write the Chemical Reaction**:
- The reaction can be represented as follows:
\[ \text{C (s) + O}_2 \text{ (g) } \rightarrow \text{CO (g) + N}_2 \text{ (g)} \]
- Here, carbon (C) reacts with oxygen (O₂) to produce carbon monoxide (CO) and nitrogen gas (N₂).

4. **Identify the Products**:
- The main gaseous fuel produced in this reaction is carbon monoxide (CO).
- The other product is nitrogen gas (N₂), which is a major component of air.

5. **Conclusion**:
- The gaseous fuel produced is carbon monoxide (CO) and its composition in the producer gas is CO and N₂.

### Final Answer:
- The name of the gaseous fuel is **Producer Gas**.
- Its composition is **CO (Carbon Monoxide) and N₂ (Nitrogen)**.
