The ah sol for naf is 82 kj/mol, and the lattice energy is -923 kj/mol. if the hydration enthalpy of sodium is 21 kj/mol more
than the hydration enthalpy of fluoride, what are the hydration enthalpies for the sodium and fluoride ions? use ah sol =-a
hat + ahhydr.
sodium: -841 kj/mol; fluoride: -862 kj/mol
sodium: -431 kj/mol; fluoride: -410 kj/mol
o sodium: -410 kj/mol; fluoride: -431 kj/mol
sodium: -389 kj/mol; fluoride: -410 kj/mol

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
