Answer:

{i}salt plus hydrogen gas.

{II}Acids react with metal carbonates or metal bicarbonates to give out carbon dioxide, along with the corresponding metal salts and water.

{III}Non-metals do not form positive ions and hence, electron loss is absent.

{iv}3 Cu ( s ) + 8 HNO 3 ( l ) → Cu ( NO 3 ) 2 ( s ) + 2 NO ( g ) + 4 H 2 O ( l )

{v}Potassium sulfate ionizes into two potassium ions with an ionic charge of +1 each and one sulfate ion, a polyatomic ion having an ionic charge of -2.

{vi}Dilute Sulphuric acid ( H 2 SO 4 ) reacts with Iron sulphide ( FeS ) to give Iron (II) sluphate ( FeSO 4 ) and Hydrogen sulphide ( H 2 S ) gas as a product

{vii}zn+2HU—>ZnU2+H2(2)

Verified answer

Answer:

{i}salt plus hydrogen gas.

(II)Acids react with metal carbonates or metal bicarbonates to give out carbon dioxide, along with the corresponding metal salts and water.

[III]Non-metals do not form positive ions and hence, electron loss is absent.

(iv)3 Cu(s) +8 HNO 3 (1) Cu(NO3)2(s) +2

NO (g)+4H2O (1)

{v}Potassium sulfate ionizes into two potassium ions with an ionic charge of +1 each and one sulfate ion, a polyatomic ion having an ionic charge of -2.

[vi]Dilute Sulphuric acid (H 2 SO 4 ) reacts with Iron sulphide (FeS) to give Iron (II) sluphate (FeSO 4) and Hydrogen sulphide (H2S) gas as a product

[vii]zn+2HU->ZnU2+H2(2)
