Fe → FeO → FeCl2 → FeOHCl → Fe(OH)2 → FeO → Fe

Question

Fe → FeO → FeCl2 → FeOHCl → Fe(OH)2 → FeO → Fe

Answer 1

2Fe+O2=2FeO

FeO+2HCl=FeCl2+H2O

FeCl2+H2O=Fe(OH)Cl+HCl

Fe(OH)Cl+H2O-->(при температуре)Fe(OH)2+HCl

Fe(OH)2-->(при температуре)FeO+H2O

FeO+H2=Fe+H2O

Answer 2

 Fe + Fe2O3 = 3FeO

FeO + 2HCl (разб.) = FeCl2 + H2O

 FeCl2 + H2O = Fe(OH)Cl + HCl

 FeOHCl + H2O = Fe(OH)2 +HCl

 Fe(OH)2 = FeO + H2O

 FeO + H2 = Fe + H2O
