CARBON DIOXIDE

Carbon dioxide (carbonic anhydride) is a colourless, poisonous, heavy gas composed of carbon and oxygen. It is the final product of the complete combustion of carbon. Carbon dioxide is present as about five percent of exhaled air. Carbon dioxie has been variously known in the past as carbonic dioxode, carbonic acid and fixed air.
