Question

Напишите уравнения реакций, при помощи которых можно осуществить следующие превращения:Zn → ZnCl2→ Zn(OH)2→ ZnO → K2ZnO2

Answer 1

Zn + Cl2 = ZnCl2 
ZnCl2 +2 NaOH = Zn(OH)2 + 2NaCl 
Zn(OH)2=ZnO+H2O 
ZnO + 2KOHизб. = K2ZnO2 + H2O

Answer 2

Chemical Reactions for the Given Transformations

To achieve the transformations Zn → ZnCl2 → Zn(OH)2 → ZnO → K2ZnO2, we can use the following chemical reactions:

1. Zn to ZnCl2: - The reaction for the transformation of Zn to ZnCl2 can be represented as: ``` Zn + 2HCl → ZnCl2 + H2 ``` - Source: [[2]](http://eprints.kname.edu.ua/37168/1/%282013%20%D0%BF%D0%B5%D1%87.%20%2022%D0%9D%20POSOBIE%2012%20%D0%BA%D0%B5%D0%B3%D0%B5%D0%BB%D1%8C%29.pdf)

2. ZnCl2 to Zn(OH)2: - The reaction for the transformation of ZnCl2 to Zn(OH)2 can be represented as: ``` ZnCl2 + 2NaOH → Zn(OH)2 + 2NaCl ``` - Source: [[8]](https://rep.vsu.by/bitstream/123456789/1980/5/%D0%9E%D0%B1%D1%89%D0%B0%D1%8F%20%D0%B8%20%D0%BD%D0%B5%D0%BE%D1%80%D0%B3%D0%B0%D0%BD%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F%20%D1%85%D0%B8%D0%BC%D0%B8%D1%8F.pdf)

3. Zn(OH)2 to ZnO: - The reaction for the transformation of Zn(OH)2 to ZnO can be represented as: ``` Zn(OH)2 → ZnO + H2O ``` - Source: Not available in the provided snippets.
