Question

Преобразовать:Fe2O3 →FeCl3 → Fe(NO3)3 → Fe(OH)3→ Fe2(SO4)3​

Answer 1

Ответ:

1) 2Fe₂O₃+6Cl₂⇒4FeCl₃+3O₂

2) FeCl₃+3HNO₃⇒Fe(NO₃)₃+3HCl

3) Fe(NO₃)₃+3H₂O⇒Fe(OH)₃+3HNO₃

4) 2Fe(OH)₃+3H₂SO₄⇒Fe₂(SO₄)₃+6H₂O

Answer 2

Conversion of Fe2O3 to Fe2(SO4)3

To convert Fe2O3 to Fe2(SO4)3, we need to go through a series of reactions. Here is the step-by-step process:

1. Fe2O3 reacts with HCl to form FeCl3 and H2O: ``` Fe2O3 + 6HCl → 2FeCl3 + 3H2O ```

2. FeCl3 reacts with HNO3 to form Fe(NO3)3 and HCl: ``` FeCl3 + 3HNO3 → Fe(NO3)3 + 3HCl ```

3. Fe(NO3)3 reacts with NaOH to form Fe(OH)3 and NaNO3: ``` Fe(NO3)3 + 3NaOH → Fe(OH)3 + 3NaNO3 ```

4. Fe(OH)3 reacts with H2SO4 to form Fe2(SO4)3 and H2O: ``` 2Fe(OH)3 + 3H2SO4 → Fe2(SO4)3 + 6H2O ```
