Question

[Thái Hưng Mai Thanh]

\(ClO_2\rightarrow SO_2\rightarrow S\rightarrow H_2S\rightarrow H_2SO_4\rightarrow HCl\rightarrow Cl_2\rightarrow NaClO\)

Answer 1

[Lê Phương Thảo]

SO2 + H2S → S + H2O

H2S + HNO3 → H2SO4 + NO2 + H2O

H2SO4 + BaCl2 → BaSO4 + HCl

HCl + MnO2 → MnCl2 + Cl2 + H2O

Cl2 + NaOH → NaCl + NaClO + H2O
