4. The common oxidation number for an alkaline earth metal is +2. (a) Using the Born-Mayer equation (for determining the lattice enthalpy) and a Born-Haber cycle (draw it), show that CaCl is an exothermic compound (negative AHf). Make a reasonable prediction to estimate the ionic radius of Ca (explain your reasoning). The sublimation (atomization) enthalpy for Ca(s) is 178 kJ/mol. (b) Show that an explanation for the non-existence of CaCl can be found in the enthalpy change for the reaction below. The AHf for CaCl2(s) is -190.2 kcal/mol. 2 CaCl(s) → Ca(s) + CaCl2(s)

X TaO, is very unlikely to exist, but let's pretend that it does. Write the balanced chemical equation for the hypothetical reaction of TaO," with ruthenium(II) ions to generate ruthenium(III) ions and Ta(11) ions in acidic aqueous solution. Do not include states of matter. XX. 8.
