Gober gas contains mainly

Options

A. `CH_4` and `O_2`
B. `CH_4` and `O_2 `
C. `CH_4` and `H_2`
D. `CH_4` and `SO_2`

Answer

**Step-by-Step Solution:**

1. **Understanding Gober Gas**: Gober gas, also known as biogas, is primarily produced from the anaerobic digestion of organic matter, particularly animal dung (gober).

2. **Anaerobic Digestion**: This process occurs in the absence of oxygen, where microorganisms break down the organic matter. The key microorganisms involved in this process are anaerobic bacteria.

3. **Composition of Gober Gas**: The main components of gober gas include:
- Methane (CH₄): This is the primary component, making up about 50-75% of the gas.
- Carbon Dioxide (CO₂): This gas constitutes about 25-30% of the composition.
- Trace gases: These include small amounts of hydrogen (H₂), nitrogen (N₂), hydrogen sulfide (H₂S), and ammonia (NH₃).

4. **Conclusion**: Therefore, the main components of gober gas are methane and carbon dioxide, with methane being the most abundant.

**Final Answer**: Gober gas contains mainly methane and carbon dioxide.
