Correct answer is 20 kJ; 50 kJ
potential energy is resting energy, that peak that's 75 kJ would be the kinetic energy
18,927.06 I believe that is the exact answer
The intermolecular force that contribute to the dissolution of sodium chloride in water are ion-dipole forces. These occurs between polar water molecules and the ions in the solution. This force is weaker than the ionic bond or the covalent bond.
