Gold(III)Oxide is Au2O3
Li2O is the chemical formula of dilithium oxide.
The balanced equation for the thermite reaction is: 2Al + Fe2O3 -> Al2O3 + 2Fe. This means that 2 moles of aluminum react with 1 mole of ironIII oxide. Therefore, if 5.591 moles of aluminum are used, 2.7955 moles of ironIII oxide will react. Since 4.821 moles of ironIII oxide are provided, the excess reagent is aluminum. The amount of excess aluminum left over is 5.591 moles - 2.7955 moles = 2.7955 moles.
Chemical formula is CaO
