Question

H²-H²O-H²SO⁴-ZnSO⁴-ZnCl²-Zn(OH)²-ZnO-H²O

Answer 1

Ответ:2Zn + O2 = 2ZnO

ZnO + H2SO4 = ZnSO4 + H2O

ZnSO4 + 2NaOH = Zn(OH)2 + Na2SO4

Zn(OH)2 + 2HCl = ZnCl2 + 2H2O

ZnCl2 + 2AgNO3 = Zn(NO3)2 + 2AgCl

Zn(NO3)2 + Mg = Mg(NO3)2 + Zn

Mg(NO3)2 + 2KOH = Mg(OH)2 + 2KNO3

Mg(OH)2 =(t°)= MgO + H2O
