carbon monoxide gas is more dangerous than carbon...

Question:
Carbon monoxide gas is more dangerous than carbon dioxide gas. Why?

Answer:

Carbon dioxide (CO₂) and carbon monoxide (CO) gases are emitted during the combustion of various fuels. Carbon monoxide is poisonous, whereas carbon-dioxide is non-toxic in nature.

Carbon monoxide is toxic because it is capable of forming a complex with haemoglobin (carboxy-haemoglobin), which is more stable than the oxygen-haemoglobin complex. The concentration range of 3-4% of carboxy-haemoglobin decreases the oxygen-carrying capacity of blood. This results in headaches, weak eyesight, nervousness, and cardiovascular disorders. A increased concentration may even lead to death.

Carbon dioxide is not poisonous. It proves harmful only at very high concentrations.
