CO2 is an abbreviation for what compound?
Cobalt Oxide
Carbon Monoxide
Carbon Dioxide
Calcium Oxide
The correct answer is: Carbon Dioxide
CO2 is an abbreviation for Carbon Dioxide, not any other compound like Cobalt Oxide, Carbon Monoxide, or Calcium Oxide. While these compounds may contain carbon, the number attached to it (2) signifies that it is referring to 2 oxygen atoms bound to 1 carbon atom. So while they may have similar elements present, they do not represent the same compound.
