Carbon Monoxide Vs. Carbon Dioxide: Let’s Compare

Oct 08, 2019· Carbon monoxide, on the other hand, is the result of incomplete combustion. Incomplete combustion happens when there is a limited supply of air, so only half as much oxygen adds to the carbon, forming carbon monoxide (CO = one oxygen atom, CO2 = two oxygen atoms). Unlike carbon dioxide, carbon monoxide does not occur naturally in the atmosphere.
