Part A Do you expect AHson to be a large positive number, a large negative number, or close to zero? Complete the sentences to explain your answer Match the items in the left column to the appropriate blanks in the sentences on the right. large positive number ion-dipole large negative number solute-solute solute-solvent solvent-solvent very similar London dispersion value close to zero dipole-dipole different AHsoln is a Reset Help This is best explained by the fact that AHsoln is determined by the relative magnitudes of the breaking (AHsolute) and (AHsolvent) interactions and the forming (AHmix) interactions. Thus, because the solute and solvent in this case experience forces, the energy required to separate them individually and the energy released when they are mixed are approximately equal.
