Question

6) Fe2O3 → FeCl3 -> Fe(NO3)3 – Fe(OH)3 - Fe2(SO4)3​

Answer 1

Объяснение:

1)FeCl3+3HNO3=Fe(NO3)3+3HCl

2)2Fe(NO3)3+3H2SO4=Fe2(SO4)3+6HNO3

3)Fe2(SO4)3+6NaOH=2Fe(OH)3+3Na2SO4

4)2Fe(OH)3=Fe2O3+3H2O

5)2Fe2O3=4Fe+3O2

Answer 2

Fe2O3 + 6HCl = 2FeCl3 + 3H2O

FeCl3 + 3AgNO3 = 3AgCl + Fe(NO3)3

Fe(NO3)3 + 3NaOH = 3NaNO3 + Fe(OH)3

2Fe(OH)3+3H2SO4=Fe2(SO4)3+6H20

Answer 3

It looks like you've provided a series of chemical reactions involving iron (Fe) and various other compounds. Let's break down these reactions step by step:

1. Fe2O3 (Iron(III) oxide) reacts with HCl (hydrochloric acid) to form FeCl3 (Iron(III) chloride):

   Fe2O3 + 6 HCl → 2 FeCl3 + 3 H2O

2. FeCl3 (Iron(III) chloride) can further react with nitric acid (HNO3) to form Fe(NO3)3 (Iron(III) nitrate):

   2 FeCl3 + 6 HNO3 → 2 Fe(NO3)3 + 6 HCl

3. Fe(NO3)3 (Iron(III) nitrate) can react with sodium hydroxide (NaOH) to form Fe(OH)3 (Iron(III) hydroxide):

   2 Fe(NO3)3 + 6 NaOH → 2 Fe(OH)3 + 6 NaNO3

4. Finally, Fe(OH)3 (Iron(III) hydroxide) can react with sulfuric acid (H2SO4) to form Fe2(SO4)3 (Iron(III) sulfate):

   2 Fe(OH)3 + 3 H2SO4 → Fe2(SO4)3 + 6 H2O

So, the overall reaction sequence is as follows:

Fe2O3 + 6 HCl → 2 FeCl3 + 3 H2O 2 FeCl3 + 6 HNO3 → 2 Fe(NO3)3 + 6 HCl 2 Fe(NO3)3 + 6 NaOH → 2 Fe(OH)3 + 6 NaNO3 2 Fe(OH)3 + 3 H2SO4 → Fe2(SO4)3 + 6 H2O

These reactions show the conversion of iron(III) oxide into iron(III) sulfate through a series of intermediate steps.
