The chart below represents different types of intermolecular forces If you have 2 substances mixed together and you know that the intermolecular forces between them are 500 kJ/mol, then which 2 substances do you think are mixed together?

A.
Xe and Kr because there are strong forces between Group 18 elements

B.
lithium bromide and water because of strong attractions between ions and polar water

C.
potassium chloride and sodium chloride because 2 solids mixed together will be highly attracted to each other since they are solids

D.
oil and water because they are not attracted to each other and would have high intermolecular forces
