What is meant by the term standard enthalpy of formation?
heat of formation, also called standard heat of formation, enthalpy of formation, or standard enthalpy of formation, the amount of heat absorbed or evolved when one mole of a compound is formed from its constituent elements, each substance being in its normal physical state (gas, liquid, or solid).
Which substances have a standard enthalpy of formation of zero?
A pure element in its standard state has a standard enthalpy of formation of zero. For any chemical reaction, the standard enthalpy change is the sum of the standard enthalpies of formation of the products minus the sum of the standard enthalpies of formation of the reactants.

What does Delta HF mean in chemistry?
In a chemical reaction, both reactants and the products they form have what are called “heats of formation.” Expressed by the symbol “ΔHf” (delta HF), heats of formation are an important part of understanding energy transfer during chemical reactions.
