(a) Account for formation of the following series of oxides in terms of the electron
Chapter 6, Problem 6.102(choose chapter or problem)
(a) Account for formation of the following series of oxides in terms of the electron configurations of the elements and the discussion of ionic compounds in Section 2.7: K20, CaO, Sc203 , TiOz, V205, Cr03 . (b) Name these oxides. (c) Consider the metal oxides whose enthalpies of formation (in kJ mol-1) are listed here. Oxide K20(s) CaO(s) Ti02(s) -363.2 -635.1 -938.7 -1550.6 Calculate the enthalpy changes in the following general reaction for each case: M110.,(s) + H2(g) ----+ nM(s) + mH20(g) (You will need to write the balanced equation for each case, then compute !J.H'.) (d) Based on the data given, estimate a value of !l.HJ for Sc203 (s).
