Question

Fe(oh)2+....=fe(oh)3

Answer 1

4Fe(OH)2+2H2O+O2=4Fe(OH)3

Answer 2

4Fe(OH)2+O2+ 2H2O=4Fe(OH)3

Answer 3

The chemical equation you provided is incomplete. It appears that you are trying to represent a redox reaction involving iron(II) hydroxide and iron(III) hydroxide, but there are reactants and products missing.

Assuming that the reaction involves the oxidation of iron(II) hydroxide to form iron(III) hydroxide, the balanced chemical equation is:

2Fe(OH)2 + 1/2O2 → Fe2O3•H2O + 2H2O

In this equation, iron(II) hydroxide (Fe(OH)2) reacts with oxygen (O2) to form iron(III) hydroxide (Fe2O3•H2O) and water (H2O). The half-reaction for the oxidation of iron(II) to iron(III) is:

2Fe(OH)2 → Fe2O3•H2O + 2H+ + 2e-

This reaction involves the loss of two electrons (e-) by each iron(II) ion (Fe2+) to form iron(III) ions (Fe3+) in the product, Fe2O3•H2O.
