I need help with determining whether the elements are precipitates. (Aqueous or solid)

Hi, I would greatly appreciate it if someone could help me out.

Out of:

  • NaCl
  • PbNO3
  • AgBr
  • SrSO4
  • ZnC2H3O2
  • FeO
  • Ba3(PO4)2
  • (NH4)2CO3
  • MgS
  • HClO3
  • and LiOH

What one are the precipatates?

Look them up. There are general rules for solubility. The insoluble ones will be precipitates.

and there are lots more if you type solubility rules into a search engine
