... Therefore, for every 0.5 moles of methane 1 mole of oxygen would be required. Looking at the quantities of reactants from step 1 there is not enough oxygen to allow all of the methane to react therefore some methane will be left over at the end. The methane is said to be in excess and the oxygen wil ...
