Question

Химия: fe cl2-- fe (oh)2-- fe o. fe ↓ ↓ -- fe cl3-- fe(oh)3-- fe2o3

baburkanybekoff · Answer

Fe + 2HCl = FeCl2 + H2FeCl2 + 2NaOH = 2NaCl + Fe(OH)2Fe(OH)2 = FeO + H2O2Fe + 3Cl2 = 2FeCl3FeCl3 + 3NaOH = 3NaCl + Fe(OH)32Fe(OH)3 = Fe2O3 + 3H2O...

> fe cl2--> fe (oh)2--> fe o. fe ↓ ↓ --> fe cl3--> fe(oh)3--> fe2o3
