Question

nitrogen

oxygen

carbon dioxide

carbon

Explanation:

Fossil fuels are composed mainly of carbon and hydrogen. When burned, they react with oxygen. The reaction produces carbon dioxide (\(CO_2\)) as a major product. Nitrogen is abundant in the atmosphere but not released from fossil - fuel combustion in significant amounts as a product. Oxygen is consumed in combustion (not released). Carbon is a solid in fossil fuels and is oxidized to form carbon dioxide gas during combustion.

Answer:

carbon dioxide
