viết phương trình hóa học hoàn thành sơ đồ sau:
\(CaO\underrightarrow{\left(1\right)}CaOH\underrightarrow{\left(2\right)}Na_2CO_3\underrightarrow{\left(3\right)}NaCl\)
\(Na_2SO_4\underrightarrow{\left(4\right)}NaCl\)
\(NaOH\underrightarrow{\left(5\right)}NaCl\)
\(NaOH\underrightarrow{\left(6\right)}Na_2SO_4\)
********HELP ME*******(mk sắp kt 45 phút rồi!!!)
CaO+H2O---->Ca(OH)2
Pt2 ko ổn lw
Na2CO3+2HCl----->2NaCl+H2O+CO2
2NaCl+H2SO4---->Na2SO4+2HCl
Na2SO4+BaCl2---->2NaCl+BaSO4
2NaCl+2H2O---->Cl2+H2+2NaOH
NaOH+HCl----->NaCl+H2O
2NaCl+H2SO4---->Na2SO4+2HCl
PTHH:CaO+H2O---->Ca(OH)2
Na2CO3+2HCl----->2NaCl+H2O+CO2
2NaCl+H2SO4---->Na2SO4+2HCl
Na2SO4+BaCl2---->2NaCl+BaSO4
2NaCl+2H2O---->Cl2+H2+2NaOH
NaOH+HCl----->NaCl+H2O
2NaCl+H2SO4---->Na2SO4+2HCl
