Compare ionization energy (<, >, or =): Sn ___ Si Cl¯ ___ Cl Li ___ Rb Ca2+ ___ Ca

f21 > Macmillan Learning Consider an ionic compound, MX3, composed of generic metal M and generic gaseous halogen X. • The enthalpy of formation of MX3 is AH = -889 kJ/mol. ⚫ The enthalpy of sublimation of M is AH sub 127 kJ/mol. • The first, second, and third ionization energies of M are IE₁ = 569 kJ/mol, IE2 1735 kJ/mol, and IE3 2683 kJ/mol. • The electron affinity of X is AHEA = -357 kJ/mol. (Refer to the hint). ⚫ The bond energy of X2 is BE = 241 kJ/mol. Determine the lattice energy of MX3. AH lattice= kJ/mol

A Review Part A Energy is reguired to remove two electrons from Ca to form Ca2+, and energy is required to add two electrons to O to form O-. Yet CaO is stable relative to the free elements. Which statement is the best explanation? O CaO is a covalent compound, and these processes are irrelevant. O CaO is stable to atmospheric conditions. O The enthalpy of formation of CaO is small. O CaO has a higher molar mass than either Ca or O O The lattice energy of CaO is large enough to overcome these processes.
