Question

Zn(OH)2=>Zn(NO3)2=>ZnCl2

Answer 1

Zn(OH)2+HNO3 => Zn(NO3)2 + H2O

Zn(NO3)2 + 2HCl => ZnCl2 +2HNO3

 

Answer 2

The chemical reactions you've mentioned involve the transformation of zinc hydroxide (Zn(OH)2) into zinc nitrate (Zn(NO3)2) and then into zinc chloride (ZnCl2). Here's the breakdown of the reactions:

1. Conversion of Zn(OH)2 to Zn(NO3)2: Zn(OH)2 + 2HNO3 → Zn(NO3)2 + 2H2O

   In this reaction, zinc hydroxide reacts with nitric acid (HNO3) to yield zinc nitrate and water.

2. Conversion of Zn(NO3)2 to ZnCl2: Zn(NO3)2 + 2HCl → ZnCl2 + 2HNO3

   In this reaction, zinc nitrate reacts with hydrochloric acid (HCl) to produce zinc chloride and nitric acid.

So, the overall reaction would be:

Zn(OH)2 + 2HNO3 + 2HCl → ZnCl2 + 2H2O + 2HNO3

Please note that in the overall reaction, nitric acid (HNO3) appears both as a reactant and a product. This is because it acts as a catalyst in the conversion of zinc hydroxide to zinc chloride, but it doesn't undergo any net change in the reaction.
