CaO+SO2=?CuO+H2SO4=?Na2O+HCL=?SO2+NaOH=?CO2+Ca(OH)2=?Ca(OH)2+Nacl=?NaOH+Mgcl2=?
问题描述：
CaO+SO2=?CuO+H2SO4=?Na2O+HCL=?SO2+NaOH=?CO2+Ca(OH)2=?Ca(OH)2+Nacl=?NaOH+Mgcl2=?
答
CaO+SO2=CaSO3
CuO+H2SO4=CuSO4+H2O
Na2O+2HCL=2NaCl+H2O
SO2+2NaOH=Na2SO3+H2O
CO2+Ca(OH)2=CaCO3+H2O
Ca(OH)2+Nacl=不反应
2NaOH+Mgcl2=Mg(OH)2+2NaCl
