ahhh this is driving me crazy...
is it possible to balance this equation:? if so, what r the coefficients?

FeC2O4*2H2O + H2C2O4 + H2O2 + K2C2O4 ---> K4[ Fe(C2O4)4 ] * 3H2O

thank you

Is that product perhaps supposed to be K₃[Fe(C₂O₄)₃] ^. 3 H₂O

And the answer to your question is I believe no, perhaps I set it up wrong but using the algebraic method I get negative coefficients required, which is not valid.

yea the subscripts for H2O and K and C2O4 were obtained from our experiment so i guess my results ended up for an impossible to balance equation... which i was just trying to check to make sure that it wasn't possible to balance...
thx

Your reaction still can be balanced, but you have to play a little bit with water:

FeC₂O₄ + H₂C₂O₄ + H₂O₂ + 2K₂C₂O₄ -> K₄[Fe(C₂O₄)₄] + 2H₂O

So, assuming that's the basic chemistry taking place (I suppose it was done in water, wasn't it?) all you have to do now is to balance crystallization water - you may safely add it and/or substract on both sides of the equation.

FeC₂O₄^.2H₂O + H₂C₂O₄ + H₂O₂ + 2K₂C₂O₄ -> K₄[Fe(C₂O₄)₄]^.3H₂O + H₂O

But Shane is right - you formula doesn't look convincing.
