Answer 1

 Fe-FeO-Fe2O3-FeCl3-Fe(OH)3-Fe2(SO4)3-FeCl3

2Fe +O2= 2FeO
4FeO +O2= 2Fe2O3
Fe2O3 +6HCL=2 FeCL3 +3H2O
FeCL3+3 NaOH= Fe(OH)3 +3NaCL
2Fe(OH)3 +3H2SO4= Fe2(SO4)3 +6H2O
Fe2(SO4)3 +3PbCL2= 2FeCL3 +3PbSO4

Answer 2

2Fe + O2 = 2FeO

2FeO + KMnO4 = Fe2O3 + KOH + MnO2

 Fe2O3 + 6HCl = 2FeCl3 + 3H2O

 FeCl3 + 3NaOH = 3NaCl + Fe(OH)3(осажд)

2Fe(OH)3 + 3H2SO4 = Fe2(SO4)3 + 6H2O

Fe2(SO4)3 + 3BaCl2 = 3BaSO4 + 2FeCl3
