A)Suppose that Li2O is added as an impurity to CaO. If the Li+substitutes for Ca2+, what kind of vacancies would you expect to form? How many of these vacancies are created for every Li+added?(b)Suppose that CaCl2is added as an impurity to CaO. If the Cl-substitutes for O2-, what kind of vacancies would you expect to form? How many of the vacancies are created for every Cl-added?
