1)Cuo+HCl=CuCl2+H2O

2)Cu+2HCl=CuCl2+h2

3)cu(oh)2+hcl=cucl2+2h2o

4)2Al(OH)3=Al2O3+3H2O

5)Na2O+H2O-2NaOH

1)CuO+2HCL=CuCL2+ H2O

Сu+2HCL=CuCL2+H2

2Cu(OH)2+4HCL=2CuCL2+H2O

2Al(OH)3=AL2O3+2H2

Na2O+H2O=2NaOH

2)2S+3O2=2SO3

SO3+H2O=H2SO4

H2SO4+2NaCL=Na2SO4+2HCL

3)2Ca+O2=2CaO

CaO+H2O=Ca(OH)2

Ca(OH)2+2NaCL=CaCL2+2NaOH
