Question
A considerable amount of heat is required for the decomposition of aluminum oxide shown below. What is the heat change when 3.5 moles of aluminum oxide are decomposed? Is this endothermic or exothermic?
2Al2O3(s) → 4Al(s) + 3O2(g) ΔH = 3352kJ
2Al2O3(s) → 4Al(s) + 3O2(g) ΔH = 3352kJ

If the reaction shown is 3352 kJ FOR THE REACTION AS SHOWN, then
dH for the question = 3352 kJ x (3.5/2) = ?
If dH is + this is an endothermic reaction.
