Did you know?
WebIn Chemistry, what you often do is take a compound and break it down to individual atoms first because you know the enthalpies for bond formations or otherwise enthalpies of individual reactions. Then you take these atoms and form the products made. You effectively do: Reactants -> Atoms -> Products, which is the equivalent of Reactants -> Products WebEquation. According to Hess’s law, enthalpy changes arising from the different steps are additive. Therefore, the overall enthalpy change of the reaction is the sum of all the …
