Question

Fe-FeO-Fe2O3-Fe2(SO4)3-Fe(OH)3​

Answer 1

1)2Fe + O2 = 2FeO
2)FeO+H2O = Fe2O3
3)Fe2O3 + 3H2SO4 =Fe2(SO4)3+3H2O
4)Fe2(SO4)3 + 6KOH =2Fe(OH)3+3K2SO4

Answer 2

It looks like you've provided a sequence of chemical compounds involving iron (Fe). These compounds represent different oxidation states and forms of iron. Let's break down each compound:

1. Fe: This is the chemical symbol for elemental iron, typically in its metallic form with an oxidation state of 0.

2. FeO: This is iron(II) oxide, also known as ferrous oxide, where iron has an oxidation state of +2.

3. Fe2O3: This is iron(III) oxide, commonly known as ferric oxide or rust. In this compound, iron has an oxidation state of +3.

4. Fe2(SO4)3: This is iron(III) sulfate. Iron in this compound also has an oxidation state of +3.

5. Fe(OH)3: This is iron(III) hydroxide. Again, iron has an oxidation state of +3 in this compound.

Each of these compounds represents iron in a different oxidation state and combined with different elements. Iron can exist in several oxidation states, which allows it to form a variety of compounds with different properties and uses in chemistry and industry. If you have specific questions about any of these compounds or their properties, feel free to ask!
