A number (eg 2) placed AFTER the symbol for an element (H, O and C etc) means that there are that many atoms of that element in the molecule.
Thus H2O means 2 Hydrogen atoms and one Oxygen atom in molecule of Water.
CO2 means there is one Carbon atom and 2 Oxygen atoms in a molecule of Carbon Dioxide.
If that says Co [ClO3]2 then it would be Cobalt II Chlorate
This reaction is:2 CO2 = 2 CO + O2
(HO)2C=O or OC(OH)2
Co(NO3)2 is cobalt (II) nitrate.
