The gas composed of one carbon atom and two oxygen atoms. Carbon dioxide is used commercially in fire extinguishers and to carbonate beverages. The gas freezes solid at minus 56Â°C and is known as dry ice in that state. At ordinary temperatures, carbon dioxide is quite unreactive; but above 1,700 Â°C it partially decomposes into carbon monoxide and oxygen.
