When Fe;04(s) reacts with H2(g) to form Fe(s) and H,O(g), 151 kJ of energy are absorbed for each mole of Fe304(s) that reacts.
Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box
for the energy term is case sensitive.
Use the SMALLEST INTEGER coefficients possible and put the energy term in the last box on the appropriate side of the equation. If a box is
not needed, leave it blank.
