assume that aqueous Ba(NO3)2 and Na2CO3 are mixed.
what ions are present in the solution?
what precipitates are possible from the reaction?
put quotations around the precipitate that is soluable.
write the complete chemical equation for the reaction.
write the next equation.
or all of this for Pb(NO3)02 and NH4I
i really dont understand how to do this type of a problem, and any help would be sincerly appreciated. thank you!

Think of a DR reaction as 2 couples coming to a dance and switching partners. In your reaction, the equation would be:
Ba(NO3)2 + Na2CO3 == 2NaNO3 + BaCO3
Break apart the compounds and you have the ions.
The NaNO3 is very soluble, but the BaCO3 has a low solubility and will precipitate.
Your question about soluble precipitate is like an oxymoron. If something precipitates, it is because it is not soluble.
Of course, solubility is heavily influenced by temperature, so if it is hot enopugh, the precipitate can dissolve.
