1) Cl2+Zn=ZnCl2 (t)
ZnCl2+2AgNO3=2AgCl↓+Zn(NO3)2
Zn(NO3)2+2NaOH=Zn(OH)2↓+2NaNO3
Zn(OH)2=ZnO+H2O (t)
ZnO+2NaOH+H2O=Na2[Zn(OH)4]
Na2[Zn(OH)4]+2HCl=Zn(OH)2↓+2NaCl+2H2O
Zn(OH)2+2NaOH=Na2ZnO2+2H2O (t)
2) 2NaBr+Cl2=2NaCl+Br2
2NaCl=2Na+Cl2↑ (эл-з)
2Na+H2=2NaH
NaH+H2O=NaOH+H2↑
2NaOH+Zn(OH)2=Na2[Zn(OH)4]
Zn(OH)2+2HCl=ZnCl2+2H2O
