Question

Fe-fecl2-fecl3-fe(oh)3-fr2(SO4)3-Fe(OH)3-Fe(OH3)3

Answer 1

Fe + 2 HCl = FeCl2 + H2 ↑
2 FeCl2 + Cl2 = 2 FeCl3
FeCl3 + 3 CsOH = Fe(OH)3 ↓ + 3 CsCl
2 Fe(OH)3 + 3 H2SO4 = Fe2(SO4)3 + 6 H2O
Fe2(SO4)3 + 6 RbOH = 2 Fe(OH)3 ↓ + 3 Rb2SO4

Answer 2

It seems like you have provided a list of chemical formulas. Let's identify each compound:

1. Fe: This is the chemical symbol for iron, which is an element.
2. FeCl2: This is iron(II) chloride, also known as ferrous chloride.
3. FeCl3: This is iron(III) chloride, also known as ferric chloride.
4. Fe(OH)3: This is iron(III) hydroxide, also known as ferric hydroxide.
5. Fr2(SO4)3: There seems to be a typo here. I assume you meant Fe2(SO4)3, which is iron(III) sulfate, also known as ferric sulfate.
6. Fe(OH)3: This is iron(III) hydroxide again, ferric hydroxide.
7. Fe(OH3)3: There is a typo here. It should be Fe(OH)3 or iron(III) hydroxide.

To summarize:

• Fe: Iron (element)
• FeCl2: Iron(II) chloride (ferrous chloride)
• FeCl3: Iron(III) chloride (ferric chloride)
• Fe(OH)3: Iron(III) hydroxide (ferric hydroxide)
• Fe2(SO4)3: Iron(III) sulfate (ferric sulfate)
• Fe(OH)3: Iron(III) hydroxide (ferric hydroxide)

Please note that the compound "Fr2(SO4)3" seems to be incorrect, and "Fe(OH3)3" has an extra "3" and should be "Fe(OH)3."
