Question

Fe-fe(oh)3-fe2(so4)3-fe2o3-fe

Answer 1

1) Fe + 3NaOH → Fe(OH)₃ + 3Na;

2) 2Fe(OH)₃+3CuSO₄ → Fe₂(SO₄)₃+3Cu(OH)₂↓

3) Fe₂(SO₄)₃(t°) → Fe₂O₃+3SO3↑

4)Fe₂O₃+2Al → 2Fe+Al₂O₃

Answer 2

It looks like you've provided a list of chemical compounds or formulas. These formulas represent different chemical species involving iron (Fe) and other elements. Let's break down each part:

1. Fe(OH)3: This is iron(III) hydroxide, a compound containing iron in the +3 oxidation state and hydroxide ions (OH-) as ligands.

2. Fe2(SO4)3: This is iron(III) sulfate, a compound containing iron in the +3 oxidation state and sulfate ions (SO4^2-) as ligands.

3. Fe2O3: This is iron(III) oxide, commonly known as rust. It contains iron in the +3 oxidation state and oxygen ions.

4. Fe: This likely represents elemental iron, which has no specific oxidation state or ligands mentioned.

It seems like you've listed different iron compounds with varying oxidation states and ligands. If you have a specific question or topic you'd like to discuss related to these compounds, please provide more context or details.
