Question

Hoàn thành chuỗi phản ứng sau Fe ---> FeCl3 --> Fe (OH)3 ---> Fe2O3 ---> FeCl3 Giúp mik vs ạ

Answer 1

\(2Fe+3Cl_2\rightarrow\left(t^o\right)2FeCl_3\\ FeCl_3+3KOH\rightarrow Fe\left(OH\right)_3+3KCl\\ 2Fe\left(OH\right)_3\rightarrow\left(t^o\right)Fe_2O_3+3H_2O\\ Fe_2O_3+6HCl\rightarrow2FeCl_3+3H_2O\)

Answer 2

2Fe+3Cl₂→(t^o)2FeCl₃

FeCl₃+3KOH→Fe(OH)3+3KCl₂

Fe(OH)₃→(t^o)Fe₂O₃+3H₂O

Fe₂O₃+6HCl→2FeCl₃+3H₂O
