*** WHAT’S COVERED ***
1. Complete vs Incomplete Combustion
* The products of burning pure hydrocarbons with plenty of oxygen (complete combustion).
* The conditions that lead to incomplete combustion.
2. Pollutants from Incomplete Combustion
* The formation of particulates (soot) and carbon monoxide.
* The health and environmental effects of particulates, including respiratory problems and global dimming.
* The dangers of carbon monoxide poisoning and how it affects the body.
3. Other Atmospheric Pollutants
* How sulfur dioxide is formed from impurities in fossil fuels.
* How nitrogen oxides are formed at high temperatures, such as in car engines.
* The environmental impact of sulfur dioxide and nitrogen oxides, including the formation of acid rain and its effects on buildings, metals, and plants.
