Answer to relevant QuestionsWhich compound in each of the following pairs of ionic substances has the most exothermic lattice energy? Jus-tify your answers. a. LiF, CsF b. NaBr, NaI c. BaCl2, BaO d. Na2SO4, CaSO4 e. KF, K2O f. Li2O, Na2S Consider the following: Li(s) + 1/2 I2(g) → LiI(s) ΔH = –292 kJ. LiI(s) has a lattice energy of –753 kJ/ mol. The ionization energy of Li(g) is 520. kJ/ mol, the bond energy of I2(g) is 151 kJ/ mol, and the electron ...Compare your answers from parts a and b of Exercise 43 with ΔH values calculated for each reaction using standard enthalpies of formation in Appendix 4. Do enthalpy changes calculated from bond energies give a reasonable ...Use bond energies (Table 6), values of electron affinities (Table 8), and the ionization energy of hydrogen (1312 kJ/ mol) to estimate DH for each of the following reactions. a. HF(g) → H+(g) + F-(g) b. HCl(g) → H+(g) + ...Explain the terms resonance and delocalized electrons. When a substance exhibits resonance, we say that none of the individual Lewis structures accurately portrays the bonding in the substance. Why do we draw resonance ...
