Problem: A large part of the driving force in a thermite reaction is based on the stability of aluminum oxide, as reflected in ΔH° of the following reaction: 2Al (s) + 3/2 O2 (g) → Al2O3 (s) ΔH° =  - 1669.8 kJ/mol   If 27 g of aluminum reacts with oxygen to form Al 2O3(s), how much heat is released assuming the reaction goes to completion?
