Na2HPO4 +HNO3 = ?
Na2HPO4 + Ba(NO3)2
Na2HPO4 + Ba(NO3)2 + HNO3
Na2HPO4 + AgNO3
Na2HPO4 + AgNO3 +HNO3
im so lost.

First equation:
Na2HPO4 + 2 HNO3 ---> 2 NaNO3 + H3PO4
Second equation:
Na2HPO4 + Ba(NO3)2 ----> 2 NaNO3 + BaHPO4
Third equation:
Na2HPO4+ Ba(NO3)2 + 2 HNO3 ----> 2 NaNO3 + Ba(NO3)2 + H3PO4 (due to common ion effect of nitrate, the Barium salt does not react completely with acid phosphate of sodium)
Fourth equation:
Na2HPO4 + 2 AgNO3 -----> 2 NaNO3 + Ag2HPO4
Fifth equation:
Na2HPO4 + AgNO3 + 2HNO3 ----> 2 NaNO3 + AgNO3 + H3PO4 (again the common ion effect of nitrate does not allow to completely react the silver salt with acid phosphate of sodium)
That is what I can remember. Hope it was useful to you.
Good luck!

I think the first one is HClO4
i think the second one is MgSO4
i think the third is Mg(NO3)2

Hmm, don't worry - balancing equations is something simple once you understand it :)
First, understand what's going on in the reaction (acid neutralisation? substitution?), and determine the products (sometimes, you have to guess).
After that, make sure the elements on both sides of the reaction equation are balanced, and that you haven't left out or added any extra atoms :)
