The balanced reaction: 2Mg + O2 → 2MgO 2 moles of Mg and 5 moles of O2 are allowed to react.Which reagent is the limiting reagent?
 Mg  O2  MgO  There is no limiting reagent  Both Mg and O2 are limiting reagents

the reaction is 2 moles + 1 mole, you have 2 and 5, so the Mg is the limiting factor and O2 is excess
