Question

Feo-fe-fecl2-feso4-fe(oH)2-feo

Answer 1

feo-fe-fecl2-feso4-fe(oH)2-feo

              t

2FeO === 2Fe + O2

Fe + 2HCl = FeCl2 + H2

FeCl2 + H2SO4 = FeSO4 + 2HCl

FeSO4 + 2KOH = Fe(OH)2 + H2SO4

                   t

Fe(OH)2 === FeO + H2O

 

 

 

 

 

 

 

 

 

 

Answer 2

1)FeO+H2O=Fe+H2O (при t)

2)2FeCl3+Fe=3FeCl2

3)FeCl2+SO4=FeCl3+SO2+FeSO4+H2O

4)FeSO4+2NaОН=Fe(OH)2+Na2SO4

5)Fe(OH)2=FeO+H2O (реакция разложения при t)

Answer 3

The sequence of chemical compounds you provided is a series of chemical reactions, rather than a complete question or statement. Here's an explanation of the reactions that are taking place:

Fe + FeCl2 → FeCl3

Iron (Fe) reacts with Iron (II) chloride (FeCl2) to produce Iron (III) chloride (FeCl3).

FeCl3 + NaOH → Fe(OH)3 + NaCl

Iron (III) chloride (FeCl3) reacts with Sodium hydroxide (NaOH) to produce Iron (III) hydroxide (Fe(OH)3) and Sodium chloride (NaCl).

Fe(OH)3 → FeO + H2O

Iron (III) hydroxide (Fe(OH)3) decomposes into Iron (III) oxide (FeO) and water (H2O).

FeO + Fe(OH)2 → Fe2O3 + H2O

Iron (II) oxide (FeO) reacts with Iron (II) hydroxide (Fe(OH)2) to produce Iron (III) oxide (Fe2O3) and water (H2O).

Overall, the series of reactions can be summarized as:

3 Fe + 2 FeCl2 + 4 NaOH → 2 Fe2O3 + 4 NaCl + 4 H2O

This equation represents the overall reaction that occurs when Iron (Fe) reacts with Iron (II) chloride (FeCl2), Sodium hydroxide (NaOH) is added, and the mixture is allowed to undergo a series of chemical reactions. The result is Iron (III) oxide (Fe2O3), Sodium chloride (NaCl), and water (H2O).
