Question

FeO → Fe(NO3)2 → Fe(OH)2 →FeO→ FeSO4​

Answer 1

Ответ:

FeO+HNo3=Fe(NO3)2+H2O.

Fe(NO3)2+NaOh=Fe(OH)2+NaNO3

Fe(OH)2=FeO+H2O

FeO+H2SO4=FeSO4+H2O

Answer 2

It appears you've written a sequence of chemical reactions involving various iron compounds. Let's break down each step:

1. FeO (Iron(II) Oxide) → Fe(NO3)2 (Iron(II) Nitrate): This reaction suggests the conversion of iron(II) oxide (FeO) to iron(II) nitrate (Fe(NO3)2). This transformation would likely involve the reaction of FeO with nitric acid (HNO3) to form Fe(NO3)2 and water (H2O):

   FeO + 2 HNO3 → Fe(NO3)2 + H2O

2. Fe(NO3)2 (Iron(II) Nitrate) → Fe(OH)2 (Iron(II) Hydroxide): This step appears to involve the conversion of iron(II) nitrate to iron(II) hydroxide. This can be achieved by adding a base (such as sodium hydroxide, NaOH) to a solution of iron(II) nitrate:

   Fe(NO3)2 + 2 NaOH → Fe(OH)2 + 2 NaNO3

3. Fe(OH)2 (Iron(II) Hydroxide) → FeO (Iron(II) Oxide): In this step, it seems like you're reverting from iron(II) hydroxide (Fe(OH)2) back to iron(II) oxide (FeO). This can be done by heating iron(II) hydroxide to remove water:

   2 Fe(OH)2 → FeO + H2O

4. FeO (Iron(II) Oxide) → FeSO4 (Iron(II) Sulfate): Finally, it appears you want to convert iron(II) oxide (FeO) to iron(II) sulfate (FeSO4). This can be achieved by reacting FeO with sulfuric acid (H2SO4):

   FeO + H2SO4 → FeSO4 + H2O

So, the overall sequence of reactions you've provided involves the conversion of iron(II) oxide to iron(II) nitrate, then to iron(II) hydroxide, followed by the reversion to iron(II) oxide, and finally the conversion to iron(II) sulfate. These reactions are feasible, but please note that the actual conditions (temperature, concentration, etc.) and yields may vary in practice, and proper safety measures should be taken when working with chemicals.
