Coal gas is a mixture of:

Options

A. `CO` and `H_(2)`
B. `H(2)`, saturated and unsaturated hydrocarbons, `CO,CO_(2),N_(2)` and `O_(2)`
C. saturated and unsaturated hydrocabons
D. `CO,CO_(2)` and `CH_(4)`

Answer

To answer the question "Coal gas is a mixture of:", we need to identify the components that make up coal gas.

### Step-by-Step Solution:

1. **Understanding Coal Gas**:
Coal gas, also known as town gas, is a combustible gas made from coal. It is produced during the carbonization of coal and is primarily used for heating and lighting.

2. **Identifying Components**:
Coal gas is primarily composed of:
- Hydrogen (H2)
- Methane (CH4) - a saturated hydrocarbon
- Carbon monoxide (CO)
- Carbon dioxide (CO2)
- Nitrogen (N2)
- Small amounts of other gases

3. **Analyzing the Options**:
Based on the components identified, we can analyze the options provided in the question. The correct mixture should include hydrogen, carbon monoxide, carbon dioxide, and nitrogen.

4. **Conclusion**:
Therefore, coal gas is a mixture of:
- Hydrogen (H2)
- Carbon monoxide (CO)
- Carbon dioxide (CO2)
- Nitrogen (N2)

### Final Answer:
Coal gas is a mixture of H2, CO, CO2, and N2.
