THE MAJOR SOURCE OF OXIDES OF NITROGEN IS FROM THE BURNING OF

• A. coal
• B. wood
• C. fuel ✓
• D. chlorofluorocarbons

The answer to the question is: C. fuel

Oxides of nitrogen, also known as nitrogen oxides (NOx), are a group of highly reactive gases that are produced during the combustion of fossil fuels. The primary sources of nitrogen oxides include vehicles, power plants, industrial facilities, and residential heating systems. These gases are formed when nitrogen in the air reacts with oxygen at high temperatures during the combustion process. The main contributors to nitrogen oxide emissions are transportation and industrial activities, particularly those involving the burning of fuel.

Nitrogen oxides have significant environmental and health impacts. They contribute to the formation of ground-level ozone and smog, which can lead to respiratory problems and other health issues. Additionally, nitrogen oxides play a role in the formation of acid rain, which can harm ecosystems, soil, and water bodies. Therefore, controlling and reducing nitrogen oxide emissions is crucial for protecting human health and the environment.
