Hi,
I have an lab I am doing in inorganic chemistry and it is where we synthesized our own compounds by adding together a bunhc of differnt ones. We are now asked to calculate the theoretical yield and they tell us which one is the limiting reagent. My question is about the equation...because in order to determine the yield you need to balance the equation first...but we are adding a whole bucnh of things together to get this product, so I don't know how you are supposed to determine the other prodcuts...would I take each part of adding together and find the products, and then those products lead to the next product until the one left is the one where I have the last product to make my new substance? But then how would I tell what the intermediate prodcuts are? Ahhh im so confused, anyways here are the compounds added:
Cl2H8MnO4 + C2H9NaO5 then once that is together you add C5H8O2 then to that product you add KMnO4 then to that product you add more C2H9NaO5 and the compound I made was C15H21MnO6 but I don't know how I determine what the other products inthe soultion were (cause we filtered it)

I think C2H9NO5 probably is sodium acetate trihydrate. There are several possibilities for C5H8O2 so you need to be more specific about what actual compound you used. It could be the ethyl ester of 2-propenoic acid as well as a number of other compounds. I think C15H21MnO6 may be manganese(III) acetyl acetylacetonate. My suggestion is that you try to fit these possibilities into the scheme of what you did. Good luck. This is not an inorganic problem entirely.
Frankly, I doubt that KMnO4 is the limiting reagent. I suppose it could be but that is for the purpose of oxidizing, probably Mn(II) to Mn(III).
In the scheme of things, 1 mole Mn = 1 mole Mn(acac)3. You need to determine where the acac came from to know its stoichiometry. Which means, of course, you need to know the intermediates.
