1. 加H2SO4
2.加HCl
3.加HCl
4.直接条件通电
5.加HCl

Cu(OH)2+2HCL=CuCl2+4H2O
CaCO3 加热→CO2+CaO
2H2O电解→2H2+O2
Zn+2HCl→H2+ZnCl2

CUO+H2SO4=CUSO4+H2O
CU(OH)2+2HCL=CUCL2+2H2O
CACO3+2HCL=CACL2+H20+CO2向上箭头
H20=电解MNO2(催化剂）H2向上箭头+O2向上箭头
ZN+2HCL=ZNCL2+H2向上箭头

1.CuO+SO3
2.CU(HO)2+2HCl
3.CaCO3高温
4.2H2O通电
5.Zn+2HCl

1.Cu(OH)2+2HCl==CuCl2+2H2O
2.CaCO3==(加热)CaO+CO2
3.2H2O+2F2==4HF+O2
4.Zn+2HCl==ZnCl2+H2
