The major source of aluminum in the world is bauxite (mostly aluminum oxide). Its thermal decomposition can be written as Al2O3 (s) → 2 Al(s) + 3/2 O2 (g) ΔH = 1676 kJ. If aluminum is produced this way, how many grams of aluminum can form when 1023 kJ of heat is transferred? Enter to 2 decimal places.
A) 68.59 grams
B) 102.88 grams
C) 137.18 grams
D) 205.76 grams
