Carbon dioxide - Wikipedia
WEBCarbon dioxide is a chemical compound with the chemical formula CO 2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature, and as the source of available carbon in the carbon cycle, atmospheric CO 2 is the primary carbon source for life on Earth.
