The following thermochemical equation is for the reaction of Fe304(s) with hydrogen(g) to form iron(s) and water(g). FezO4(s) + 4H2(g)3Fe(s) + 4H2O(g) AH = 151 kJ When 71.1 grams of Fe3O4(s) react with excess hydrogen(g), kJ of energy are Hint: An amount of energy is expressed as a positive number. The sign of AH in the thermochemical equation indicates whether the energy is absorbed or evolved.
