The AHsol 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 = - Hat+ AH hydr
Osodium: -841 kJ/mol; fluoride: -862 kJ/mol
Osodium: -431 kJ/mol; fluoride: -410 kJ/mol
O sodium: -410 kJ/mol; fluoride: -431 kJ/mol
Osodium: -389 kJ/mol; fluoride: -410 kJ/mol

AHsol untuk NaF adalah 82 kJ/mol, dan energi kisinya adalah -923 kJ/mol. Jika entalpi hidrasi natrium adalah 21 kJ/mol

lebih dari entalpi hidrasi fluorida, berapa entalpi hidrasi untuk ion natrium dan fluorida? Gunakan

Hsol = - Hat+ AH hydr

Natrium: -841 kJ/mol; fluorida: -862 kJ/mol

Natrium: -431 kJ/mol; fluorida: -410 kJ/mol

O natrium: -410 kJ/mol; fluorida: -431 kJ/mol

Natrium: -389 kJ/mol; fluorida: -410 kJ/mol
