The compound CO is known as carbon monoxide.
Carbon monoxide is a colorless, odorless gas that can be harmful when inhaled in large amounts. It is formed during the incomplete combustion of carbon-containing materials, such as fossil fuels and biomass. Because it binds with hemoglobin in the blood more effectively than oxygen, high levels of carbon monoxide can lead to serious health risks, including poisoning and even death.
Understanding carbon monoxide is important, especially in contexts where combustion occurs, as proper ventilation and detection can help avoid dangerous situations.
