'Naming Molcules' gives a chemical formula and asks for the name, while 'Identifying Molecules' gives the name and asks for the formula.
The Oxidation activity requires you to input the oxidation numbers for all atoms in a given molecule.
'Moles and Grams' requires you to calculate the molar mass of a given molecule, and use it to convert between grams and moles.
