Since the balanced equation shows 2 moles of Al2O3 formed, its ΔH should be double the amount given for 1 mole, so: 4 Al(s) + 3 O2(g) → 2 Al2O3(s), ΔH = -3339.6 kJ. Here we have the balanced chemical equation for the thermite reaction. We can write, quite simply, that the change in enthalpy is equal to the delta H formation of aluminum oxide minus the delta H formation of iron oxide. Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al 2 O 3.It is the most commonly occurring of several aluminium oxides, and specifically identified as aluminium(III) oxide.It is commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Religious, moral and philosophical studies. 2 moles of aluminum react with 1 mole of iron oxide, forming 2 moles of iron and 1 mole of aluminum oxide.
