Question

Zn-Zn(OH)2-K2ZnO2-Zn(NO3)2-ZnCO3-ZnO-K2ZnO2-ZnCl2 !!!!!!

Answer 1

Zn + Cl2 -> ZnCl2
ZnCl2 + 2NaOH -> Zn(OH)2↓ + 2NaCl
Zn(OH)2 + 2KOH -> K2ZnO2 + 2H2O
K2ZnO2 + 4HNO3 -> Zn(NO3)2 +2 KNO3 + 2H2O
Zn(NO3)2 + Na2CO3 -> ZnCO3 ↓+ 2NaNO3
ZnCO3 -> ZnO + CO2↑
ZnO + 2KOH -> K2ZnO2 + H2O
K2ZnO2 +4 HCl -> ZnCl2 + 2KCl + 2H2O

Answer 2

Zn + Cl2 = ZnCl2

ZnCl2 + 2NaOH = Zn(OH)2↓ + 2NaCl

Zn(OH)2 + 2KOH = K2ZnO2 + 2H2O

K2ZnO2 + 4HNO3 = Zn(NO3)2 +2KNO3 + 2H2O

Zn(NO3)2 + Na2CO3 = ZnCO3↓+ 2NaNO3

ZnCO3  =t°=> ZnO + CO2↑

ZnO + 2KOH = K2ZnO2 + H2O

K2ZnO2 + 4HCl = ZnCl2 + 2KCl + 2H2O

Answer 3
