Final answer:
The gas that is not usually released from burning fossil fuels is nitrogen gas (N₂). Option 1
Step-by-step explanation:
The gas that is not usually released from burning fossil fuels is N₂ (nitrogen gas).
When fossil fuels such as coal, oil, and natural gas are burned, they primarily release carbon dioxide (CO₂), sulfur dioxide (SO₂), and nitrogen oxides (NOx). These gases contribute to air pollution and global warming.
However, nitrogen gas (N₂) is not usually released directly from burning fossil fuels. Nitrogen gas makes up a large portion of the Earth's atmosphere and is relatively inert, so it does not undergo combustion during the burning of fossil fuels. Option 1
