Standard enthalpies of fromation are usually computed from the
calorimetric data referring to reactions, which are easy to carry
out in the laboratory. For many compounds, the enthalpy of the
reaction with O2 (g) (combustion) is commonly used, together with
the standard enthalpies of formation of the combustion products, to
compute ΔHf°. For example, sucrose C12H22O11, common table sugar,
is found to have a standard enthalpy of combustion of -5640.9
kJ/mole. The standard enthalpies of formation of CO2 (g) and...

The standard heat of formation, ΔH∘f, is defined as the
enthalpy change for the formation of one mole of substance from its
constituent elements in their standard states. Thus, elements in
their standard states have ΔH∘f=0. Heat of formation
