•6CO2 stands for 6 carbon dioxide molecules. The “C” stands for 1 carbon atom. The “O” stands for 1 oxygen atom. The “2” means this molecule has 2 oxygen atoms.

•Carbon dioxide is found in the air and in water, both fresh and saltwater. It is produced by all organisms when they use food as energy.

•6H2O stands for 6 water molecules. The “H” stands for 1 hydrogen atom. The “O” again is oxygen. And, again the “2” means this molecule has 2 hydrogen atoms.
