Give three ions that are isoelectronic with krypton. Place these ions in order of increasing size.
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 ...
