Answer to Question #56340 in General Chemistry for sue

Question #56340
Balance the molecular equations based on the reactions you mixed together and write the complete ionic equations and net ionic equations for all of the reactions that you tested that gave you a precipitate. if you got "no reaction" because you did not get a precipitate, then write the ionic equation by listing the ions for all the aqueous solutions on the reactant side and then an ---> and the words "no reactions". CuSO4(aq) + Ba(NO3)2(aq) -----> Cu(NO3)2 + BaSO4
Expert's answer
The balanced equation:
CuSO4(aq) + Ba(NO3)2(aq) → Cu(NO3)2 (aq) + BaSO4 (s)
Complete ionic equation:
Cu2+(aq) + SO42–(aq) + Ba2+(aq) + 2NO3–(aq) → Cu2+ (aq) +2NO3– (aq)+ BaSO4 (s)
Net ionic equation:
SO42–(aq) + Ba2+(aq)→ BaSO4 (s)
BaSO4 (s) is insoluble in water, so it precipitates, leaving the reaction media, and the reaction occurs to the end.
