The following thermochemical equation is for the reaction of iron(III) oxide(s) with hydrogen(g) to form iron(s) and water(g).
Fe203(s) + 3H2(g) 2Fe(s) + 3H20(g)
AH = 98.8 kJ
When 59.9 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.
