The correct answer is D. All the above.
Oxidation is a chemical reaction that involves the loss of electrons. In the process of oxidation, a substance combines with oxygen or another oxidizing agent, and the oxidation number of one or more atoms in the substance increases.
The formation of carbon dioxide, nitrates, and sulfates are all examples of oxidation reactions. When carbon-containing compounds are oxidized, they react with oxygen to form carbon dioxide. When nitrogen-containing compounds are oxidized, they react with oxygen to form nitrates. When sulfur-containing compounds are oxidized, they react with oxygen to form sulfates.
Oxidation reactions are important in many biological and chemical processes. For example, the oxidation of glucose in the human body produces energy. The oxidation of iron in the atmosphere produces rust.
Here are some additional details about each of the options:
- Carbon dioxide is a gas that is produced when organic matter is burned. It is also a major component of the Earth’s atmosphere.
- Nitrates are salts of nitric acid. They are found in fertilizers and explosives.
- Sulfates are salts of sulfuric acid. They are found in rocks, minerals, and seawater.
