Construct a Born-Haber cycle for the formation of the hypothetical compound NaCl2, where the sodium ion has a 2+ charge (the 2nd ionization energy for sodium is given in Table 7.2 in the textbook).

Part B

If we were to estimate the lattice energy of NaCl2 to be roughly equal to that of MgCl2 (2326 kJ/mol from Table 8.2 in the textbook), what value would you obtain for the standard enthalpy of formation, ΔH∘f, of NaCl2?

Express your answer using four significant figures.

The element titanium displays an exceptional affinity for oxygen and when heated in air immediately forms TiO2. This substance is the most widely used white pigment in paints, cosmetic skin care products, and sunscreens. The +4 oxidation state for Ti should, because of the high charge and small ionic radius (82pm), be difficult to stabilize in an ionic lattice. Indeed, for years I have taught that ionic charges > +3 are not stable in ionic structures. Perform appropriate calculations, using...
