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 A
Hsol = - Hiat + Hydro
O sodium: -841 kJ/mol; fluoride: -862 kJ/mol
Osodium: -431 kJ/mol; fluoride: -410 kJ/mol
O sodium: -410 kJ/mol; fluoride: -431 kJ/mol
O sodium: -389 kJ/mol; fluoride: -410 kJ/mol

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.
