Question 4:

What are the primary products of fossil fuel combustion?

A) Oxygen and water
B) Carbon dioxide and water
C) Carbon dioxide and nitrogen
D) Carbon monoxide and sulfur dioxide

Show Answer

Explanation: The correct answer is B) Carbon dioxide and water. The primary products of fossil fuel combustion are carbon dioxide (CO2) and water (H2O). When fossil fuels burn, carbon in the fuel combines with oxygen from the air to form CO2, while hydrogen in the fuel combines with oxygen to form water vapor.
