Question

Fe(OH)=Fe2O3+H2O (help pls)

Answer 1

2Fe(OH)3 (t)= Fe2O3 + 3H2O

Answer 2

The equation you have written is not balanced and is missing some information about the state of the reactants and products. However, I think you meant to write the following balanced equation:

Fe(OH)3(s) → Fe2O3(s) + 3H2O(g)

This equation represents the thermal decomposition of iron(III) hydroxide into iron(III) oxide and water vapor. When heated, solid iron(III) hydroxide decomposes into solid iron(III) oxide and gaseous water. The balanced equation shows that for every one mole of iron(III) hydroxide, two moles of iron(III) oxide and three moles of water vapor are produced.
