when aluminum metal reacts with iron (III) oxide to form aluminum oxide and iron metal, 429.6 kJ of heat are given off for each mole of aluminum metal consumed, under constant pressure and standard conditions. What is the correct value for the standard enthalpy of reaction in the thermochemical reaction...

  1. If 429.6 kJ of heat are given off for each mole of Al and there are 2 mols of Al in the balanced equation, then there must be 2 x 429.6 kJ released for 2 mols of Al.
