Answer 1

\(2KMnO_4+16HCl\rightarrow2KCl\left(A\right)+2MnCl_2+5Cl_2\left(C\right)+8H_2O\left(D\right)\)

\(KCl\left(A\right)+H_2O\left(D\right)\xrightarrow[cmn]{đpdd\:}KOH\left(E\right)+\dfrac{1}{2}Cl_2\left(C\right)+\dfrac{1}{2}H_2\left(F\right)\)

\(Cl_2\left(C\right)+H_2\left(F\right)\underrightarrow{as}2HCl\)

\(3Cl_2\left(C\right)+6KOH\left(E\right)\underrightarrow{t^o}5KCl\left(A\right)+KClO_3\left(G\right)+3H_2O\left(D\right)\)

\(KClO_3\left(G\right)+6HCl\rightarrow KCl\left(A\right)+3Cl_2\left(C\right)+3H_2O\left(D\right)\)

\(A:KCl\\ B:MnCl_2\\ C:Cl_2\\ D:H_2O\\ E:KOH\\ F:H_2\\ G:KClO_3\)
