Question
Why are carbon and its compounds used as fuels for most applications?
✓
Answer
- When carbon is burnt in the presence of air or oxygen, it forms carbon dioxide and water with a release of a large amount of heat and light.
- $\mathrm{C}(\mathrm{s})+\mathrm{O}_2(\mathrm{~g}) \rightarrow \mathrm{CO}_2(\mathrm{~g})+$ Heat + Light
- When carbon and its compounds are burnt, additional heat energy is not required for consistent burning.
- Hence, carbon and its compounds are used as fuels for most applications.
