​

Answer 1

Answer:

Acidic oxides: S O 2 , C O 2 , N O 2 SO_2,CO_2,NO_2 SO2,CO2,NO2

Basic oxides: N a 2 O , K 2 O , C a O Na_2O,K_2O,CaO Na2O,K2O,CaO.

Amphoteric oxides: Z n O , P b O , A l 2 O 3 ZnO,PbO,Al_2O_3 ZnO,PbO,Al2O3

Neutral oxides: N O , C O , N 2 O NO,CO,N_2O NO,CO,N2O.

Answer 2

Acidic oxides are oxides that react with water to form an acid Eg . Silicon, phosphorus, sulphur, and chlorine oxides are acidic.
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either. react with water to form a base; or. react with an acid to form a salt and water which are called neutralization reactions. Eg Sodium oxide, which reacts with water to produce sodium hydroxide. Magnesium oxide, which reacts with hydrochloric acid to form magnesium chloride.
