Concept: Enthalpies of Formation 

The enthalpy change for a mole of a substance that combines with oxygen under standard conditions of 1 bar and 298 K is known as the standard enthalpy of combustion. The enthalpy of formation can be found using the equation: ΔHfº = ΔHproducts - ΔHreactants. Then, use this to find the enthalpy for 1 mole of Fe.
