Объяснение:
Fe → FeCl2 → Fe(OH)2 → FeO → Fe
Fe + Cl2 = FeCl2
FeCl2 + 2KOH = Fe(OH)2 + 2KCl
Fe(OH)2 = H2O + FeO
FeO + CO = Fe + CO2↑
Fe → FeCl3 → Fe(OH)3 → Fe2O3 → Fe → Fe2(SO4)3
2Fe + 3Cl2 = 2FeCl3
FeCl3 + 3NaOH = 3NaCl + Fe(OH)3
2Fe(OH)3 = Fe2O3 + 3H2O
Fe2O3 = 2Fe + O3
2Fe + 6H2SO4 = Fe2(SO4)3 + 3SO2 + 6H2O
