1) 2AgNO3(aq) + CoCl2(aq)==> 2AgCl(s) + Co(NO3)2 is the balanced molecular equation.
The balanced net ionic equation is (using the smallest set of numbers)
Ag^+(aq) + Cl^-(aq) ==> AgCl(s)
You need to know the solubility rules to do these. Here is a simplified set of same.

Write the balanced, complete, and net ionic equations for each precipitation reaction.
1) AgNO_3 + CoCl_2 --->
BE: AgNO_3(aq) + CoCl_2(aq) ---> AgCl_2 (aq) + Co(NO_3)(aq)
CIE: Since the balanced equation is all (aq) there is no reaction so no complete or net equation.
2) AgNO_3 + Na_2CrO_4 --->
BE: AgNO_3 (aq) + Na_2CrO_4 (s) ---> AgCrO_4 (s) + Na_2(NO_3) (aq)
CIE: Ag^+ (s) + NO_3- (aq) + Na_2^+ (s) + CrO_4 ^2- (s) ---> AgCrO_4 (S) + Na_2^+ (s) + (NO_3)^- (aq)
NIE: Ag^+ (s) + CrO_4^2- (s) ---> AgCrO_4^2- (s)
Are these answers correct. Thank you for your help!!!
