H2+Cl2=2HCl

2HBr+Ca(OH)2=CaBr2+2H2O

2KI+CL2=KCL2+I2

 2NaOH(конц, хол) + Br2 = NaBrO + NaBr + H2O

2Na+2H2O=2NaOH+H2  

 

Fe2O3 + 3H2 = 2Fe + 3H2O

Fe+Br2=FeBr2

FeBr2+2NaF=FeF2+2NaBr

H2+Cl2=2HCl

2HBr + Ca(OH)2 =CaBr2+2H2O 

2 KL + Cl2 = 2 KCl

2NaOH + Br2 =NaBr + NaBrO + H2O

2 Na + 2 H2O = 2 NaOH +H2

 

 

Fe2O3 - Fe -Fe Br 2- Fe F2 = 

Fe2O3 +2Al= Al2O3 +2Fe

Fe+Вr2=FeBr2

FeBr2+2NaF=FeF2+2NaBr
