Cân bằng các phương trình: Cl2 + NaOH -> CL2 + Ki -> Cl2 + Nh3 -> CL2 + NH3 -> CL2 + H2S + H2O ->

Đáp án:

(1) $Cl_{2}$ + $2NaOH_{}$ -> $H_{2}$ $O_{}$ +$NaCl_{}$ + $NaClO_{}$

(2) $Cl_{2}$ + $2Ki_{}$ -> $i_{2}$ + $2KCl_{}$ 

(3)và(4) giống nhau: $Cl_{2}$ + $NH_{3}$ -> $6HCl_{}$+ $N_{2}$ 

(5) $Cl_{2}$ + $H_{2}$ $S_{}$ +$H_{2}$ $O_{}$ -> $H_{2}$ $SO_{4}$ + $HCl_{}$
