Calculate the lattice formation enthalpy (lattice energy) of the lattice for LiF(s), in kJ/mol, given the following information: Sublimation energy for Li(s) 161 kJ/mol AH: for F(g) 77 kJ/mol First ionization 520 kJ/mol energy of Li(g) Electron affinity of F(g) -328 kJ/mol Enthalpy of formation of LİF(s) -617 kJ/mol

Consider the following data for silver: atomic mass 107.87 g/mol electronegativity 1.93 electron affinity 125.6 kJ/mol ionization energy 731.0 kJ/mol heat of fusion 11.3 kJ/mol Does the following reaction absorb or release energy? (1) Ag(g) -> Ag+(g) + e- Is it possible to calculate the amount of energy absorbedor released by reaction (1) using only the data above? If you answered yes to the previous question, enter theamount of energy absorbed or released by reaction (1): Does the following reaction absorb or release energy? (2) Ag- (g) -> Ag(g) + e-  Is it possible to calculate the amount of energy absorbedor released by reaction (2) using only the data above? If you answered yes to the previous question, enter theamount of energy absorbed or released by reaction (2):

Calculate the average A-B bond energy in AB3(g). AH for AB3(g)=-75.9 kJ/mol, AH, for A(g) = 288.9 kJ/mol, AH, for B(g) = 134.9 kJ/mol, AH for A2(g) = 0 kJ/mol, AH for B2(g)=0 kJ/mol. Enter a number in kJ/mol to 1 decimal place.
