Question

Zn(OH)2------>ZnO ZnO------>Zn Zn------>Zn(NO3)2

Answer 1

                 t

Zn(OH)2 = ZnO + H2O

ZnO + С = Zn + CO

4Zn + 10HNO3 (очень разб) = 4Zn(NO3)2 + NH4NO3 + 3H2O

 

 

 

 

Answer 2

The given chemical reactions can be summarized as follows:

1. Zn(OH)2 → ZnO This reaction involves the conversion of zinc hydroxide to zinc oxide. The chemical equation for this reaction is:

Zn(OH)2 → ZnO + H2O

2. ZnO → Zn This reaction involves the reduction of zinc oxide to metallic zinc. The chemical equation for this reaction is:

ZnO + C → Zn + CO

Here, carbon (C) is used as a reducing agent.

3. Zn → Zn(NO3)2 This reaction involves the reaction of zinc with nitric acid to form zinc nitrate. The chemical equation for this reaction is:

Zn + 2HNO3 → Zn(NO3)2 + H2

Here, nitric acid (HNO3) is used as an oxidizing agent to convert metallic zinc to zinc nitrate. The hydrogen gas (H2) produced in the reaction is a by-product.
