This is a balancing eqn Im finding rather tricky:

Question

___Fe(NH4)2(SO4)2 6H2O + ___ H2C2O4 + ___K2C2O4 + ___ H2O2 ---> ___K5Fe1(C2O2)2 3H2O + ___(NH4)2(SO4) + ___H2SO4 + ___ H2O

remember H2O2, an oxidizing agent, was used in synthesis, so youll nee to do a redox balance. Start with just iron ions, balance the rxn, then add the full formulas.

Thanks!

Answer 1

my mistake, the first molecule in the products should be K3Fe(C2O4)3 3H20

Answer 2

Check this out. You fill in the blank for water.
2,3,3,1,==>2,2,2,??H2O

Answer 3

I have been having trouble with this as well. Would the coefficient of water be 5,8, or 2? I have heard all of these and I got 5 when I worked it out, but I have been told that it is wrong.
