Question

Fe-Fe2O3-Fe2(So4)3-Fe(OH)3-Fe2O3-Fe

Answer 1

Ответ:

1) 2Fe(+0) + 3O(+0)→ Fe2(+3)O3(-2)

2) Fe2O3 + 3H2(+1)SO4(-2) → Fe2(3+)(SO4)3(-2) + 3H2O

3) Fe2SO4 + 2NaOH →2 Fe(OH)3 + Na2SO4

4)2 Fe(OH)3→Fe2O3+ H2O

2Fe2O3 →4 Fe + 3O2

Answer 2

The sequence you provided appears to be a combination of chemical formulas representing different iron compounds. Here's a breakdown of each compound:

1. Fe: This represents elemental iron, which is the pure form of iron.

2. Fe2O3: This is iron(III) oxide, commonly known as rust. It is a compound formed by the combination of two iron atoms with three oxygen atoms.

3. Fe2(SO4)3: This is iron(III) sulfate, a compound formed by the combination of two iron atoms with three sulfate ions (SO4^2-) that carry a -2 charge each.

4. Fe(OH)3: This is iron(III) hydroxide, a compound formed by the combination of three hydroxide ions (OH-) with one iron(III) ion.

5. Fe2O3: This is iron(III) oxide, as mentioned earlier.

6. Fe: This represents elemental iron, similar to the first compound in the sequence.

Each of these compounds represents different forms or combinations of iron with oxygen, sulfate, and hydroxide ions.
