Question

On burning, fossil fuel gives:

• A. Oxides of Carbon
• B. Oxides of Nitrogen
• C. Oxides of Sulphur
• D. All of the above

Hint:

Burning fossil fuels releases carbon dioxide, nitrogen oxides, and sulfur oxides, all of which contribute to environmental pollution.

Answer 1

The Correct Option is D

When fossil fuels (such as coal, oil, and natural gas) are burned, they release a variety of gases as byproducts. These gases include:
- Oxides of Carbon (mainly \( \text{CO}_2 \), carbon dioxide, and in some cases \( \text{CO} \), carbon monoxide).
- Oxides of Nitrogen (mainly \( \text{NO}_x \) compounds, which include nitrogen oxides like \( \text{NO} \) and \( \text{NO}_2 \)).
- Oxides of Sulphur (mainly \( \text{SO}_2 \), sulfur dioxide).
These pollutants contribute to environmental issues such as air pollution, acid rain, and global warming.
Thus, the correct answer is (D) All of the above.
