1)3Fe+2O2--> Fe2O3+ FeO(Fe3O4)
2)Fe2O3+6HCl-->2FeCl3+3H2O
3)FeCl3+3NaOH-->Fe(OH)3+3NaCl
4)2Fe(OH)3--(t,C)-->Fe2O3+3H2O
5)Fe2O3+3C--> 2Fe + 3CO
6)Fe+ 2HCl--> FeCl2 +H2

3Fe + 2O2 = Fe3O4
Fe3O4 = Fe2O3 + FeO
Fe2O3 + 6HCL = 2FeCL3 + 3H2O
FeCL3 + NaOH = 3Fe(OH)3 + 3NaCl
2Fe(OH)3 --t--> Fe2O3 + 3H2O
Fe2O3 + 3CО = 2Fe + 3CO2
Fe + 2HCl = FeCL2 + H2
