4) NaClO+2HCl->NaCl+Cl2+H2O

5) Cl2+2NaOH->NaCl+NaClO+H2O

6) 2NaCl+2H2O->2NaOH+H2+Cl2

7) Cl2+2NaOH->NaCl+NaClO+H2O

8) 2NaCl+2H2O->2NaOH+Cl2+H2

9) 2NaClO+H2O+CO2->Na2CO3+Cl2+H2O

10) NaHCO3+HCl->NaCl+CO2+H2O

11) CO2+NaAlO2+2H2O->NaHCO3+Al(OH)3

12) CaCO3->CaO+CO2

13) 2CaOCl2+CO2+H2O->CaCO3+CaCl2+H2O

14) CaCl2+Na2CO3->2NaCl+CaCO3

15) CaCl2+Na2CO3->2NaCl+CaCO3

16) 2CaOCl2->2CaCl2+O2

17) CaF2+H2SO4->CaSO4+2HF

18) 4HF+SiO2->SiF4+2H2O
