2Zn + O2 = 2ZnO
ZnO + 2HCl = ZnCl2 + H2O ==> ZnCl2 + 2NaOH = Zn(OH)2 + 2NaCl
Zn(OH)2 + 2HCl = ZnCl2 + 2H2O
ZnCl2 + H2SO4 = ZnSO4 + 2HCl
2ZnSO4 (t)= 2ZnO + 2SO2 + O2
ZnO + H2 (t)= Zn + H2O
2Zn + O2 = 2ZnO
ZnO + 2HCl = ZnCl2 + H2O ==> ZnCl2 + 2NaOH = Zn(OH)2 + 2NaCl
Zn(OH)2 + 2HCl = ZnCl2 + 2H2O
ZnCl2 + H2SO4 = ZnSO4 + 2HCl
2ZnSO4 (t)= 2ZnO + 2SO2 + O2
ZnO + H2 (t)= Zn + H2O
