Question

Cu(OH)2>CuO>CuSO4>Cu(OH)2

ZnO>ZnCl2>Zn(OH)2>Na2ZnO2 

Составьте уравнение химических реакций

Answer 1

$1.Cu(OH)_2>CuO>CuSO_4>Cu(OH)_2\1)Cu(OH)_2=CuO+H_2O\2)CuO+H_2SO_4=H_2O+CuSO_4\3)CuSO_4+2NaOH=Na_2SO_4+Cu(OH)_2$

$2.ZnO>ZnCl_2>Zn(OH)_2>Na_2ZnO_2 \1)ZnO+2HCl=H_2O+ZnCl_2\2)ZnCl_2+2NaOH=2NaCl+Zn(OH)_2\3)Zn(OH)_2+2NaOH=Na_2ZnO_2+2H_2O$ 

Answer 2

1.Cu(OH)2+NaO=CuO+2NaOH

CuO+Li2SO4=CuSO4+Li2O

CuSO4+2AgOH=Cu(OH)2+Ag2SO4

 2.ZnO+2NaCl=ZnCl2+Na2O

ZnCl2+2AgOH=Zn(OH)2+2AgCl

Zn(OH)2+2NaOH=Na2ZnO2+2H2O
