| August 12, 2021 | education
Values:
1. Zn – zinc;
2. ZnO – zinc oxide;
3. ZnCl2 – zinc chloride;
4. Zn (OH) 2 – zinc hydroxide;
The chain of transformations.
Zinc – Zinc Oxide:
2 Zn + O2 = 2 ZnO;
Zinc Oxide – Zinc Chloride:
ZnO + 2 HCl = ZnCl2 + H2O;
Zinc Chloride – Zinc Hydroxide
ZnCl2 + 2 NaOH = Zn (OH) 2 + 2 NaCl;
Answer: 2 ZnO; ZnCl2 + H2O; Zn (OH) 2 + 2 NaCl;
