Question

Fe-->Fe2O3-->Fe2(SO4)3-->Fe(OH)3→ Fe2O3->Fe(NO3)3-->Fe(OH)3​

Answer 1

Ответ:

4Fe+3O²=2Fe²O³

Fe²O³+3 H²SO⁴= Fe²(SO⁴)³+3 H²O

Fe²(SO⁴)³+6NaOH= 2Fe(OH)³+3 Na²SO⁴

2Fe(OH)³= Fe²O³+3H²O

Fe²O³+6HNO³= 2Fe(NO³)³+ 3H²O

Fe(NO³)³+3KOH= Fe(OH)³+3 KNO³

Answer 2

The given chemical reaction sequence involves the transformation of iron (Fe) through various compounds. Let's break down each step of the reaction sequence: 1. **Fe → Fe2O3**: This step represents the oxidation of iron to form iron(III) oxide (Fe2O3), also known as rust. Iron reacts with oxygen in the presence of moisture to form this compound [[1]]. 2. **Fe2O3 → Fe2(SO4)3**: In this step, iron(III) oxide reacts with sulfuric acid (H2SO4) to produce iron(III) sulfate (Fe2(SO4)3). The reaction can be represented as follows: ``` Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O ``` Iron(III) oxide reacts with sulfuric acid to form iron(III) sulfate and water [[2]]. 3. **Fe2(SO4)3 → Fe(OH)3**: The next step involves the reaction of iron(III) sulfate with a base, such as sodium hydroxide (NaOH), to form iron(III) hydroxide (Fe(OH)3). The balanced equation for this reaction is: ``` Fe2(SO4)3 + 6NaOH → 2Fe(OH)3 + 3Na2SO4 ``` Iron(III) sulfate reacts with sodium hydroxide to produce iron(III) hydroxide and sodium sulfate [[3]]. 4. **Fe(OH)3 → Fe2O3**: In this step, iron(III) hydroxide undergoes dehydration to form iron(III) oxide. The reaction can be represented as: ``` 2Fe(OH)3 → Fe2O3 + 3H2O ``` Iron(III) hydroxide decomposes to form iron(III) oxide and water [[4]]. 5. **Fe2O3 → Fe(NO3)3**: The next step involves the reaction of iron(III) oxide with nitric acid (HNO3) to produce iron(III) nitrate (Fe(NO3)3). The balanced equation for this reaction is: ``` Fe2O3 + 6HNO3 → 2Fe(NO3)3 + 3H2O ``` Iron(III) oxide reacts with nitric acid to form iron(III) nitrate and water [[5]]. 6. **Fe(NO3)3 → Fe(OH)3**: The final step in the given reaction sequence involves the reaction of iron(III) nitrate with a base, such as sodium hydroxide, to form iron(III) hydroxide. The balanced equation for this reaction is: ``` Fe(NO3)3 + 3NaOH → Fe(OH)3 + 3NaNO3 ``` Iron(III) nitrate reacts with sodium hydroxide to produce iron(III) hydroxide and sodium nitrate. In summary, the given reaction sequence involves the transformation of iron through various compounds, including iron(III) oxide, iron(III) sulfate, iron(III) hydroxide, and iron(III) nitrate. Each step represents a specific chemical reaction involving different reactants and products. I hope this explanation helps! Let me know if you have any further questions.
