-->Fe Cl2-->Fe (OH)2-->Fe O. Fe ↓ ↓ -->Fe Cl3-->Fe(OH)3-->Fe2O3

Question

-->Fe Cl2-->Fe (OH)2-->Fe O.
Fe ↓ ↓

-->Fe Cl3-->Fe(OH)3-->Fe2O3

Answer 1

Fe + 2HCl = FeCl2 + H2
FeCl2 + 2NaOH = 2NaCl + Fe(OH)2
Fe(OH)2 = FeO + H2O
2Fe + 3Cl2 = 2FeCl3
FeCl3 + 3NaOH = 3NaCl + Fe(OH)3
2Fe(OH)3 = Fe2O3 + 3H2O
