Question

Fe2O3->Fe2(SO4)3->Fe(NO3)3

Answer 1

Ответ:

Fe2O3 → Fe2(SO4)3 → Fe(NO3)3

Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O

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

Answer 2

It seems like you're presenting a series of chemical reactions involving iron (Fe) compounds. Let me break down each step for you:

1. Fe2O3: This represents iron(III) oxide, also known as rust or hematite. It's a compound consisting of iron and oxygen.

2. Fe2(SO4)3: This represents iron(III) sulfate. It's a compound formed by reacting iron(III) oxide with sulfuric acid (H2SO4). The reaction would look something like:

   Fe2O3 + 3 H2SO4 → Fe2(SO4)3 + 3 H2O

3. Fe(NO3)3: This represents iron(III) nitrate. It's a compound formed by reacting iron(III) sulfate with nitric acid (HNO3). The reaction would look something like:

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

In summary, these reactions show a transformation from iron(III) oxide to iron(III) sulfate, and then from iron(III) sulfate to iron(III) nitrate through subsequent reactions with appropriate acids.
