The following thermochemical equation is for the reaction of iron(III) oxide(s) with hydrogen(g) to form Fe304 and water(g). 3Fe,O3(s) + H2(g)→2F¢304(s) + H,0(g) AH=-6.00 kJ When 34.5 grams of iron(III) oxide(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.
