A) Predict the order of increasing basicity for the Group II oxides MgO, CaO, SrO, and BaO.
|a)||CaO, MgO, SrO, and BaO|
|b)||SrO, BaO, CaO, and MgO|
|c)||BaO, SrO, CaO, and MgO|
|d)||MgO, CaO, SrO, and BaO|
B) Iron can exist as either Fe2O3 (hematite) or FeO (w�stite). Which is the most acidic oxide?
|b)||Neither dissolves in water, so they are neither acidic nor basic.|
|d)||They are the same.|
