Question

Fe(OH)3-Fe2O3-Fe2(SO4)3-Fe(OH)3

Answer 1

1)Fe(OH)3=(температура)=Fe2O3+3H2O
2)Fe2O3+3H2SO4=Fe2(SO4)3+3H2O
3)Fe2(SO4)3+6KOH=2Fe(OH)3+3K2SO4
   2Fe+3SO4+ 6K+6OH=2Fe(OH)3+6K+3SO4(сокращаем)
   2Fe+6OH=2Fe(OH)3
В последней реакции проставить заряды ионов:Fe(3+);K(+);OH(-);SO4(2-)

Answer 2

The chemical formula you provided contains four different chemical species, all containing iron (Fe) ions. They are:

1. Fe(OH)3: Iron(III) hydroxide, a yellowish-brown solid that is insoluble in water. Its chemical formula is Fe(OH)3.

2. Fe2O3: Iron(III) oxide, a reddish-brown solid that is commonly known as rust. Its chemical formula is Fe2O3.

3. Fe2(SO4)3: Iron(III) sulfate, a white or yellowish solid that is soluble in water. Its chemical formula is Fe2(SO4)3.

4. Fe(OH)3: Iron(III) hydroxide, a yellowish-brown solid that is insoluble in water. Its chemical formula is Fe(OH)3.

It is not clear what you are asking about these species. If you have a specific question or want more information, please let me know.
