Sim WenHong 2P3 23 Carbon monoxide

Carbon monoxide is a chemical compound made up by carbon and oxygen. It is only slightly lighter than air, however, highly toxic to humans and animals if over inhaled. Ironically, it is produced during metabolism, thus it is believed to have some normal biological functions. The atoms, one carbon and one oxygen atom are combined in a unique triple bond that is made up of two covalent bonds. Carbon monoxide is also known to be the most fatal air pollutant and killer in the world, partly because it is colorless, tasteless and odorless but highly toxic. It is also used in meat-coloring as it gives a bright cherry-pink color when reacted with myoglobin.
