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

If one fission reaction of a uranium-235 atom produced two neutrons, how many neutrons would be released if the chain reaction occurred three more times?

Vi limitens. vastery test select the correct answer. which statement explains why large atoms are more reactive than small atoms? a. large atoms have valence electrons farther from the nucleus and lose them more readily. b. large atoms have greater ionization energy, which they can utilize during a reaction. c. large atoms have a greater number of electrons that they can lose during a reaction. d. large atoms have more energy levels, so they have more energy to pass on in a reaction. reset next
