Answer 1

Fe-FeCl3-Fe(OH)3-Fe2O3-Fe-Fe2(SO4)3-Fe(NO3)3
1) 2Fe+3Cl2=2FeCl3
2)FeCl3+3NaOH=Fe(OH)3+3NaCl
3)2Fe(OH)3=Fe2O3+3H2O
4)Fe2O3+3C=2Fe+3CO
5)2Fe+6H2SO4=Fe2(SO4)3+3SO2+6H2O
6)Fe2(SO4)3+3BaNO3=2Fe(NO3)3+3BaSO4
2) ионное
FeCl3+3NaOH=Fe(OH)3+3NaCl
Fe+3 + 3Cl- + 3Na+ + 3OH- =Fe(OH)3 + 3Na+ + 3Cl-
Fe+3 + 3OH- =Fe(OH)3
