Question

Fe->FeCl3->Fe(OH)3->Fe2O3->Fe2(SO4)3->FeCl3.giúp mk câu này với ,mk đang cần gấp

 

 

Answer 1

\(2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\)

\(FeCl_3+3NaOH\rightarrow Fe\left(OH\right)_3\downarrow+3NaCl\)

\(2Fe\left(OH\right)_3\rightarrow Fe_2O_3+3H_2O\)

\(Fe_2O_3+2H_2SO_4\rightarrow Fe_2\left(SO_4\right)_3+2H_2O\)

\(Fe_2\left(SO_4\right)_3+3BaCl_2\rightarrow2FeCl_3+3BaSO_4\downarrow\)

Answer 2

Fe+3/2CI2 (t*)->FeCI3

FeCI3+3NaOH->Fe(OH)3+3NaCI
2Fe(OH)3 (t*)-> Fe203+3H20

Fe2(S04)3+3BaCI2->3BaS04+2FeCI3
