Question

Fe - FeO - Fe(OH)2 - FeCl

Answer 1

Fe+PbO=FeO+Pb

FeO+H2O=Fe(OH)2

Fe(OH)2+2HCl=FeCl2+2H2O

Answer 2

The series of chemical compounds you provided includes iron and its different oxidation states combined with various elements:

1. Fe: This represents metallic iron in its elemental form, where iron has an oxidation state of 0.

2. FeO: This is iron oxide, commonly known as wustite. In this compound, iron has an oxidation state of +2 (Fe^2+), and oxygen has an oxidation state of -2 (O^2-). The formula indicates that one iron atom combines with one oxygen atom.

3. Fe(OH)2: This compound is known as iron(II) hydroxide or ferrous hydroxide. Here, iron has an oxidation state of +2 (Fe^2+), and hydroxide ions (OH^-) have a charge of -1. The formula indicates that one iron atom combines with two hydroxide ions.

4. FeCl: The formula provided seems to be incomplete. Iron can form various chlorides with different oxidation states. For example, iron(II) chloride has the formula FeCl2, where iron has an oxidation state of +2 (Fe^2+), and two chloride ions (Cl^-) with a charge of -1 each are present. Another common iron chloride is iron(III) chloride, with the formula FeCl3, where iron has an oxidation state of +3 (Fe^3+), and three chloride ions are present.

If you intended to provide a specific iron chloride compound, please clarify the oxidation state of iron and the number of chloride ions in the compound.
