Answer #1

Precipitation reactions: (C₂H₂O₂) + 2Nach Hga ela + 2 Na C₂H302 Ppt 2) 261 + Pb(NO3)2 = PbI2 + 215 NO3 ppt 3) Ba(NO3)2 + Cu30Hg2Cl2 , PbI2 and BaSO4 all are insoluble in water due to their bulky size and less positive effective nuclear energy which is not enough to make hydration shells around them.

Rest all reactions are non precipitating
