Bond enthalpyis the energy required to form or break a given bond. Its value can change between molecules, even for the same type of bond. For example, the bond energy of H2O's two O−H bonds is 464 kilojoules per mole (kJ/mol), but in methanol (CH3OH) the one O−H bond has...
Or, you could describe it as the enthalpy change when 1 mole of sodium chloride (or whatever) is broken up to form its scattered gaseous ions. In other words, you are looking at an upward arrow on the diagram. In the sodium chloride case, that would be 787 kJ mol-1. Both refer to...

What energy change takes place when bonds are made? Energy given out Energy taken in Energy taken in and then given out Energy given out and then taken in 2. Multiple Choice 1 min 1 pt What energy change takes place when bonds are broken? Energy given out Energy taken in Ener...
Traditionally, MM has been supposed unsuitable for modeling reaction mechanisms where bonds are made and broken. The change of connectivity between reactant(s) and product(s) generates different reference states, the reaction energies cannot usually be directly compared and the FF is not able to ...
(A) Energy of NH3 as one of the N–H bonds is stretched until broken, i.e., the BDE of the first bond of ammonia. (B) NBO hybridizations of the nitrogen orbitals used to bond to the hydrogens not being stretched and the hybridization of the lone pair-containing orbital. (C) NBO...
