Question

Fe-x-y-Fe2O3 А)FeO. И FeCl б)FeS и Fe(OH)3 В)Fe(OH)3 и FeCl3 4) FeCl3 и Fe(OH)3

Answer 1

Ответ:

4

Объяснение:

Первая реакция будет:

2Fe+3Cl2=2FeCl3

вторая:

FeCl3+3NaOH=Fe(OH)3(осадок)+3NaCl

И последняя- разложение при нагревании

2Fe(OH)3=Fe2O3+3H2O

Answer 2

To balance the equation, we need to determine the correct coefficients for each compound. The given reaction seems to represent a combination of two iron (Fe) compounds with some other substances (x, y) to produce Fe2O3. Let's analyze each option:

A) FeO and FeCl

Fe + FeO + FeCl → Fe2O3

This option does not seem balanced, as we have three different iron-containing compounds on the left side and only one on the right side of the equation.

B) FeS and Fe(OH)3

FeS + Fe(OH)3 → Fe2O3

This option does not seem balanced either, as we have two different iron-containing compounds on the left side and only one on the right side of the equation.

C) Fe(OH)3 and FeCl3

Fe(OH)3 + FeCl3 → Fe2O3

This option also does not seem balanced, as we have two different iron-containing compounds on the left side and only one on the right side of the equation.

D) FeCl3 and Fe(OH)3

FeCl3 + Fe(OH)3 → Fe2O3

This option seems to be the most balanced option among the given choices. We have one iron-containing compound on each side of the equation, and it is a reasonable reaction that could take place. Iron(III) chloride (FeCl3) and iron(III) hydroxide (Fe(OH)3) combine to form iron(III) oxide (Fe2O3).

So, the correct answer is:

D) FeCl3 and Fe(OH)3
