Bạn ơi!
Mình thắc mắc về 2 pt trên! Bạn giải thích giùm mình nha!

1. KMnO4 -> Cl2 -> HCl -> Cl2 -> NaCl -> HCl -> Dung Dịch HCl -> FeCl2 -> AgCl

$KMnO_4+ HCl \rightarrow KCl+MnCl_2+Cl_2+H_2O$

$H_2+Cl_2 \rightarrow HCl$

$HCl + MnO_2 \rightarrow MnCl_2+Cl_2+H_2O$

$Cl_2+Na \rightarrow NaCl $

$NaCl + H_2SO_4(đ) \xrightarrow{t^o<250^oC} NaHSO_4+HCl\uparrow$

$HCl$ cho vào nước --> dung dịch HCl

$HCl+Fe \rightarrow FeCl_2+H_2$

$FeCl_2+AgNO_3 \rightarrow Fe(NO_3)_2+AgCl$
