Among Al_(2)O_(3), SiO_(2),P_(2)O_(3) and SO_(2) , the correct order of acid strength is :

Among Al_(2)O_(3),SiO_(2),P_(2)O_(5) and SO_(3) the correct order of acid strength is :-

Among Al_(2)O_(3),SiO_(2),P_(2)O_(5) and SO_(3) the correct order of acid strength is :-

Among Al_(2)O_(3),SiO_(2),P_(2)O_(3) and SO_(2) the correct order of acid strength is

Identify the satements which are not correct ? (i) ZnO,PbO,Sb_(2)O_(3) are neutral oxides. (ii) CO and NO are amphoteric oxides. (iii) CrO_(3),Mn_(2)O_(7),V_(2)O_(5) are basic oxides.

For given oxides calculate (("X"+"Y"))/(2) FeO,Cr_(2)O_(3),MnO,ZnO,CO,Na_(2)O,Al_(2)O_(3), PbO_(2) ,BaO where : X= Number of oxides which reacts only with acid Y= Number of neutral oxides "]
