1.-Why are group 1 B elements more stable than group 1 Aelements even though they seem to have the same outer electronconfiguration, ns1, where n is the principal quantumnumber of the outermost shell? 2.-Write balanced equations for the reactions between each ofthe following oxides and water: a) Li2O, b)CaO, c) SO3 3.-Which oxide is more basic, MgO or BaO? why? 1.-Why are group 1 B elements more stable than group 1 Aelements even though they seem to have the same outer electronconfiguration, ns1, where n is the principal quantumnumber of the outermost shell? 2.-Write balanced equations for the reactions between each ofthe following oxides and water: a) Li2O, b)CaO, c) SO3 3.-Which oxide is more basic, MgO or BaO? why? 3.-Which oxide is more basic, MgO or BaO? why?Explanation / Answer
2.-Write balanced equations for the reactions between each ofthe following oxides and water: a) Li2O Li2O + H 2 O ------> 2 LiOH b) CaO CaO + H 2 ------> Ca ( OH )2 c) SO3 SO3 + H 2 O ----> H2 SO 4 3.Which oxide is more basic, MgO or BaO BaO is more basic The oxides of Be & Mg are so tightly held togetherin the solid state that they are insoluble in water . The heaviermetal oxides react with water to form soluble hydroxides which arestrong bases. 3.Which oxide is more basic, MgO or BaO BaO is more basic The oxides of Be & Mg are so tightly held togetherin the solid state that they are insoluble in water .
