How to Calculate Delta H F By Robert Schrader; Updated April 24, 2017 In a chemical reaction, both reactants and the products they form have what are called heats of formation. Expressed by the symbol ÎHf (delta HF), heats of formation are an important part of understanding energy transfer during chemical reactions. In order to calculate ÎHf for any product or reactant, you must have on hand the total amount of heat the reaction produces (ÎH), as well as the ÎHf value for all the other reactants and/or products, all of which your chemistry problem will provide you.
The band Toto sand the song, I Miss the Rain Down in Africa. It is about man who must choose between Africa and his woman.
