Question

Fe-Fecl3-Fe2(so4)3-?-Fe2o3-Fe

Answer 1

2Fe + 3Cl2 = 2FeCl3

2FeCl3+3H2SO4=Fe2(SO4)3+6HCl

 Fe2(SO4)3+6NaOH=3Na2SO4+2Fe(OH)3

2Fe(OH)3=Fe2O3+3H2O

Fe2O3+Al=Fe+Al2O3

Answer 2

1) 2Fe + 3Cl2 = 2FeCl3

2) 2FeCl3 + 3H2SO4 = Fe2(SO4)3 + 6HCl

3) Fe2(SO4)3 + 6NaOH = 3Na2SO4 + 2Fe(OH)3

4)2Fe(OH)3 = Fe2O3 + 3H2O

5) Fe2O3 + 3CO = 2Fe + 3CO2

Answer 3

The given sequence of compounds represents a possible series of chemical reactions that could occur between iron (Fe) and various reactants:

Fe + FeCl3 → FeCl2 + FeCl4 (unbalanced)

FeCl2 + FeCl3 → Fe2Cl5

Fe2Cl5 + 3H2O → 2Fe(OH)3 + 5HCl

2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O

Fe2(SO4)3 → Fe2O3 + 3SO3

Fe2O3 + 3H2 → 2Fe + 3H2O

The question mark represents an unknown product, which could be the result of a further reaction involving one of the compounds in the sequence. Without more information, it is difficult to determine what this product might be.

It is worth noting that the sequence as written is not balanced in terms of the number of atoms of each element on each side of the equations. Balancing the equations would provide more information about the relative amounts of each compound involved in the overall reaction.
