Question

Fe+FeBr3→Fe(OH3)3→Fe(OH)3→Fe2O3→Fe​

Answer 1

Ответ:

Fe2O3 + 6HCl = 3H2O + 2FeCl3 FeCl3 + 3KOH = 3KCl + Fe(OH)3 (осадок) 2Fe(OH)3 (t) = 3H2O + Fe2O3 Fe2O3 + 3CO = 2Fe + 3CO2

Answer 2

The reaction you've written appears to be a series of chemical reactions involving iron (Fe) and iron(III) bromide (FeBr3) that ultimately results in the formation of iron(III) oxide (Fe2O3).

Here's a step-by-step breakdown of the reactions:

1. Fe + FeBr3 → Fe2Br6 This is a redox reaction in which iron (Fe) reacts with iron(III) bromide (FeBr3) to form iron(III) hexabromide (Fe2Br6).

2. Fe2Br6 + 6 NaOH → 2 Fe(OH)3 + 6 NaBr Here, iron(III) hexabromide reacts with sodium hydroxide (NaOH) to produce iron(III) hydroxide (Fe(OH)3) and sodium bromide (NaBr).

3. 2 Fe(OH)3 → Fe2O3 + 3 H2O This is a dehydration reaction where iron(III) hydroxide (Fe(OH)3) decomposes to form iron(III) oxide (Fe2O3) and water (H2O).

So, the overall reaction sequence is:

Fe + FeBr3 → Fe2Br6 Fe2Br6 + 6 NaOH → 2 Fe(OH)3 + 6 NaBr 2 Fe(OH)3 → Fe2O3 + 3 H2O

The final product of this series of reactions is iron(III) oxide (Fe2O3).
