Question

Combustion of fossil fuels in insufficient air produces ___________ instead of carbon dioxide.

Answer 1

Fossil fuels:

A hydrocarbon-containing material is generated underground from the residues of deceased plants and animals.

Features of fossil fuels:

1. Fossil fuels are generally composed of carbon (C) and hydrogen (H).
2. During combustion, carbon and hydrogen combine with atmospheric oxygen (O₂) to produce carbon dioxide (CO₂).
3. When combustion remains incomplete, a part of the carbon does not oxidize completely, leading to carbon monoxide production.

Combustion of fossil fuels in insufficient air produces carbon monoxide instead of carbon dioxide.
