Question

Fe ⟶ FeO ⟶ FeCl2 ⟶ Fe(OH)2 ⟶ FeO ⟶ FeSO4

Answer 1

Ответ:

Объяснение:

2Fe  +  O2  =  FeO

FeO + 2 HCl  =  FeCl2  +  H2O

FeCl2 (p-p)  + 2KOH (p-p) =  Fe(OH)2  + 2KCl

                                                осадок

Fe(OH)2 ------t-------   FeO +  H2O (пар)

FeO +  H2SO4  =  FeSO4   +  H2O

Answer 2

It looks like you've provided a sequence of chemical reactions involving iron (Fe) and various compounds. Let's go through each step of the sequence:

1. Fe ⟶ FeO: This represents the reaction of iron (Fe) with oxygen (O₂) to form iron(II) oxide (FeO), also known as ferrous oxide.

2. FeO ⟶ FeCl₂: This step seems to involve the reaction of iron(II) oxide (FeO) with hydrochloric acid (HCl) to form iron(II) chloride (FeCl₂).

3. FeCl₂ ⟶ Fe(OH)₂: This step likely involves the reaction of iron(II) chloride (FeCl₂) with a base (such as sodium hydroxide, NaOH) to form iron(II) hydroxide (Fe(OH)₂).

4. Fe(OH)₂ ⟶ FeO: This step might indicate that the iron(II) hydroxide (Fe(OH)₂) is undergoing a dehydration reaction to produce iron(II) oxide (FeO) again.

5. FeO ⟶ FeSO₄: This step could involve the reaction of iron(II) oxide (FeO) with sulfuric acid (H₂SO₄) to form iron(II) sulfate (FeSO₄).

It's important to note that the sequence you've provided involves several reactions, and the actual products and outcomes can depend on reaction conditions, concentrations, and other factors. If you have specific questions about any of these reactions or the chemistry involved, feel free to ask!
