Complete the equation determine if there are precipitates write the balanced ionic and net ionic equations. if there is no precipitate write the balances molecular and ionic equations:
sr(no3)2(aq)+k3po4(aq)=
naoh(aq)+ni(no3)2=

Is there a picture or answer choices?

Your question is not clear but if you can explain yourself i would be glad to .  just trying to : ))

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
