As the title states, how do I know when the products will react or not react in these examples?
HI(aq) + Zn(NO3)2(aq) --> ?
CuSO4(aq) + Na2CO3(aq) --> ?
Cu(NO3)2(aq) + Na3PO4(aq) --> ?
Thanks!

Solubility rules, mayhaps?

Yeah. Shoulda figured this out on my own.
I have to look at the products and use the solubility table/rules to determine which form aqueous products and which form solid products. If all the products are aqueous, then no reaction occurs because its all just ions floating around.
I'm sure I'll be corrected by someone who knows better if I'm wrong.

Don't be so hard on yourself, it isn't obvious when you're just learning it!
But you have the right idea. Make sure you keep in mind that many of the solubility rules will have exceptions. A lot of the time, those exceptions are the ones your teacher will assign.
