Question

Fe-feso4-fe(oh)2-feo-fe-fecl3

Answer 1

Fe + H2SO4 -> FeSO4 + H2
FeSO4 + 2NaOH -> Fe(OH)2 + Na2SO4
Fe(OH)2 -> FeO + H2O
2FeO ->2 Fe + O2
2Fe +3 Cl2 -> 2FeCl3

Answer 2

The sequence of chemical reactions represented by the given formula is:

Fe + FeSO4 → FeFe(SO4)2 (a double displacement reaction) FeFe(SO4)2 + 2NaOH → Fe(OH)2 + Na2SO4 + FeSO4 (a double displacement reaction) 4Fe(OH)2 + O2 → 2Fe2O3 + 4H2O (an oxidation-reduction reaction) Fe2O3 + 6HCl → 2FeCl3 + 3H2O (a double displacement reaction)

Overall, the sequence of reactions is:

Fe + FeSO4 + 2NaOH + O2 + 6HCl → 2FeCl3 + 3H2O

This reaction sequence shows the transformation of iron (Fe) from its elemental form to FeCl3 (iron(III) chloride), with intermediate steps involving FeSO4 (iron(II) sulfate), Fe(OH)2 (iron(II) hydroxide), and Fe2O3 (iron(III) oxide).
