The overall reaction in a commercial heat pack can be represented as 4 Fe(s) + 302(g) → 2 Fe₂O3(s) AH = -1652 kJ a. How much heat is released when 4.80

moles of iron are reacted with excess O₂? Heat = kj b. How much heat is released when 1.00 mole of Fe2O3 is produced? Heat = kj c. How much heat is released when 1.40 g iron is reacted with excess O₂? Heat = kj d. How much heat is released when 11.0 g Fe and 1.80 g O2 are reacted? Heat = kj
