The chemical formula for carbon monoxide is CO. This compound consists of one carbon atom and one oxygen atom. Carbon monoxide is a colorless, odorless gas that can be harmful or fatal when inhaled in significant quantities, as it interferes with the body's ability to transport oxygen. It is produced during the incomplete combustion of carbon-containing fuels, such as gasoline and natural gas. Although it has few industrial applications, it is essential to monitor and control CO emissions to protect human health and the environment.
