Changed superscript 2 to subscript in chemical formula of carbon dioxide (!) edit

The template had a superscript 2 instead of a subscript 2 in CO2. The error in this should be self-explanatory; the right upper quadrant beside an elemental symbol is reserved for charge, not the number of atoms of that element in a formula.
