Just a slight change according to me: (all except PbI2 should be aqueous)
Pb(NO3)2 (aq) + 2NaI (aq) ===> PbI2 (s) + 2NaNO3 (aq)
___________ _______________ ______________ ___________
Ionic reaction:
Pb(2+) + 2NO3(-) + 2Na(+) + 2I- ===> PbI2 (s) + 2Na+ + 2NO3-.
Na+ and NO3- are spectator ions.

recognize your solubility regulations: All nitrates are soluble. All team I metallic salts are soluble. So, NO3- and ok+ do not type something and stay in answer. Many bromides are soluble, yet silver bromide is insoluble. So, the precipitate will be silver bromide: Ag+ (aq) + Br- (aq) --> AgBr(s) The spectator ions are those that do not type a precipitate. accordingly, they are NO3- and ok+. i desire that facilitates! P.S: heavily, recognize your solubility regulations! they are needed for issues like those.
