Achieve #18

How would be balance an equation for the formation of Fe2O3 * 3H2O? I know that the reactants would be Fe, O2, and H2O.
I thought that it would be 4Fe + 3 O2 + 6 H2O --> 2 Fe2O3 * 6H2O, however this is the correct answer. Does anyone know how to go about doing this?

What you have listed is the correct answer, make sure that you are using subscripts and the correct arrow sign provided by achieve. The way to do this would be to list the reactqnts Fe+O2+H2O-->Fe2O3*H2O and balance iron, hydrigen, and oxygen atoms like you would do in a normal reaction and add coefficients to make sure iron, oxygen, and hydorge atoms are equal on both sides.
