Question

Осуществить следующие превращения: Fe(NO3)3→Fe(OH)3→Fe2O3→Fe→FeCl2→Fe(OH)2 Помогите на экзамены по химиии))Заранее спасибо))

Answer 1

Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3

2Fe(OH)3 = Fe2O3 + 3H2O

Fe2O3 + 3H2 = 2Fe + 3H2O

Fe+2HCl=FeCl2+H2

FeCl2+2NaOH=2NaCl+Fe(OH)2

Answer 2

Fe(NO3)3 + 3KOH = Fe(OH)3 + 3KNO3

2Fe(OH)3 = Fe2O3 + 3H2O

Fe2O3 + 3H2 = 2Fe + 3H2O

Fe+2HCl = FeCl2+H2

FeCl2+2NaOH = 2NaCl+Fe(OH)2

Answer 3

Превращения Fe(NO3)3 → Fe(OH)3 → Fe2O3 → Fe → FeCl2 → Fe(OH)2

1. Fe(NO3)3 → Fe(OH)3: - Fe(NO3)3 reacts with water (H2O) to form Fe(OH)3 and nitric acid (HNO3) as a byproduct. - The balanced chemical equation for this reaction is: Fe(NO3)3 + 3H2O → Fe(OH)3 + 3HNO3 [[2]](http://elcat.pnpu.edu.ua/docs/HIM-2011-09.pdf).

2. Fe(OH)3 → Fe2O3: - Fe(OH)3 can be dehydrated to form Fe2O3 (iron(III) oxide) through the loss of water molecules. - The balanced chemical equation for this reaction is: 2Fe(OH)3 → Fe2O3 + 3H2O [[1]](https://www.calameo.com/books/0018325624928d74bfd0e).

3. Fe2O3 → Fe: - Fe2O3 can be reduced to elemental iron (Fe) by heating it with carbon (C) in a process called reduction. - The balanced chemical equation for this reaction is: Fe2O3 + 3C → 2Fe + 3CO [[1]](https://www.calameo.com/books/0018325624928d74bfd0e).

4. Fe → FeCl2: - Elemental iron (Fe) reacts with chlorine gas (Cl2) to form iron(II) chloride (FeCl2). - The balanced chemical equation for this reaction is: Fe + Cl2 → FeCl2 [[1]](https://www.calameo.com/books/0018325624928d74bfd0e).

5. FeCl2 → Fe(OH)2: - Iron(II) chloride (FeCl2) can react with water (H2O) to form iron(II) hydroxide (Fe(OH)2) and hydrochloric acid (HCl) as a byproduct. - The balanced chemical equation for this reaction is: FeCl2 + 2H2O → Fe(OH)2 + 2HCl [[2]](http://elcat.pnpu.edu.ua/docs/HIM-2011-09.pdf).

Summary of the transformations: Fe(NO3)3 → Fe(OH)3 → Fe2O3 → Fe → FeCl2 → Fe(OH)2

Please note that these reactions are simplified representations and may not take into account specific reaction conditions or other factors that may affect the reactions. It's always important to consider the specific context and conditions when studying chemistry.
