Would NH3 form a precipitate when mixed with...?
Would NH3 form a precipitate when mixed with...?
HC2H3O2
KNO3
CaCl2
BaCl2
FeCl3
HCl
Ni(NO3)2
CuSO4
AgNO3
Pb(NO3)2
I have no idea how to find the net ionic equations of them too... because of NH3. I'm really confused with NH3. If it was something else then i wouldn't have much trouble.
the NH3 isn't in water.
It is NH3. if it was NH4+, i wouldn't have a problem. i know what you are usually supposed to do, but i don't know what to do with NH3.

Think of it this way and you'll get it. NH3 in water is sligtly basic, so it forms ammonium hydroxide: NH4OH. NH4OH in turn dissociates into NH4+ ions and OH- ions. So ammonia is really not participating in the ionic eactions with all the choices you have listed. You will get a precipitate with any compound on your list when the positive ion of that compound forms an insoluble hydroxide salt.
Check me on this, but I think Ca, Ba, Fe, Ni, Cu, Ag, and Pb all form insoluble hydroxides.

Do you mean NH4? NH3 is not likely to be available to react, as it is neither an anion nor cation as written.
You need to break each of the compounds that you have listed into their ionic components (one cation and one anion). Then substitute the species of interest for the corresponding one in the original compound. Then compare the potential product to your solubility rules.
For example: K2CO3 with Ni(2+)... K(+) ions, CO3(2-) ions and Ni(2+) ions present in solution... switch Ni(2+) for Na(+)... possible product is NiCO3... this compound in insoluble
