Chapter 15, Problem 54E

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 GI:

K₂O, CaO, Sc₂O₃, Ti0₂, V₂0₅, CrO₃.

Name these oxides.

Consider the metal oxides whose enthalpies of formation (in (in kJ mo1-1) are listed here.

Oxide	K₂0(s)	Ca0(s)	Ti02(s)	V₂0₅(s)
Alff	-363.2	-635.1	-938.7	-1550.6

Calculate the enthalpy changes in the following general reaction for each case:

M_nO_m(s) + H₂(g) ->nM(s) + mH₂O(g)

(You will need to write the balanced equation for each case and then compute ΔH°. )(d) Based on the data given, estimate a value ofΔHf ° for Sc₂0₃(s).
