Question

Give the scientific reason for the following statement.

Carbon monoxide is dangerous when inhaled.

Answer 1

Carbon monoxide $\left(\mathrm{CO}\right)$:

Carbon monoxide $\left(\mathrm{CO}\right)$ is an invisible, colorless gas produced by inefficient fuel combustion.

Carbon monoxide is dangerous:

1. When carbon monoxide is inhaled and absorbed into the bloodstream, it combines with hemoglobin to create an irreversible compound known as carboxyhemoglobin.
2. The development of this compound lowers the blood's oxygen-carrying ability.
3. If the blood oxygen levels get too low, then the body may not function properly.
4. It can impair heart and brain function in severe cases.
5. As a result, carbon monoxide is very harmful when inhaled.
