### BALANCE CHEMICAL EQUATIONS

Does anybody have time to assist me balancing the following chemical equations ? I have started already with some. I do believe some equations cannot be solved. I'll appreciate any assistance.

NH3 + H3PO4 =
CO(NH2)2 + H3PO4 =
HNO3 + H3PO4 =
NH4OH + H3PO4 =
NH3 + KOH =
CO(NH2)2 + KOH =
HNO3 + KOH =
NH4OH + KOH =
NH3 + KCl =
CO(NH2)2 + KCl =
HNO3 + KCl =
NH4OH + KCl =
NH3 + K2CO3 =
CO(NH2)2 + K2CO3 =
HNO3 + K2CO3 =
NH4OH + K2CO3 =
NH3 + H3PO4 + KOH =
CO(NH2)2 + H3PO4 + KOH =
HNO3 + H3PO4 + KOH =
NH4OH + H3PO4 + KOH =
NH3 + H3PO4 + KCl =
CO(NH2)2 + H3PO4 + KCl =
HNO3 + H3PO4 + KCl =
NH4OH + H3PO4 + KCl =
NH3 + H3PO4 + K2CO3 =
CO(NH2)2 + H3PO4 + K2CO3 =
HNO3 + H3PO4 + K2CO3 =
NH4OH + H3PO4 + K2CO3 =

What do you expect now. Better is you write your ideas, then we can discuss.

### Re: BALANCE CHEMICAL EQUATIONS

As mentioned, I've started balancing some of the equations. I am struggling though when there are 3 reactants. I really want to look for compatibility of mixing.

The background - I've looked at the nutrient constituents on some complex NPK fertilisers. With the exception of Urea (also somewhat puzzling, because the final product contains H2O too), the rest do not correspond with theoretical calculations.

Want to use these balanced equations (along with theoretical constituent determination), to ask a fertiliser supplier or two why the difference.

Acid + Base gives salt + water.
So it depends how much from each is added what happend.
Like KOH + H3PO4 you can have 3 different results. KH2PO4, K2HPO4 and K3PO4.
Ammonia gives Ammonium NH4+
Urea decompose with acids to ammonia and carbondioxide.
Salt1 + acid1 gives Salt2 + acid2, in solution you have only ions
So will KCl + HNO3 give K+, H+, Cl- and NO3-
This would also happen if you mix KNO3 and HCl.
Mixture of two acids give only mixture nothing more. Adding base give mixture of the salts.
Pottasium carbonate will decompose with acids to carbondioxide.

Thanks SO much for time taken to respond. Appreciated.

Do you by any chance know of an online program / tool, in which 2 or more reactants can be input, with (a) predictive product(s) ?
