Problem

The first square is labeled B a C l 2 (aq) and contains six circles. Four of the circles are labeled as C l with a negative charge and two slightly smaller circles are labeled as B a with positive two charge. The second square is labeled as N a 2 C O 3 (aq) and has six circles. It has four smaller circles labeled as N a with a positive one charge and two circles labeled as C O 3 with a negative two charge.
The solutions of BaClA2(aq) and NaA2COA3(aq) represented above are mixed, causing a precipitate to form. The balanced equation for the reaction is shown below.
BaClA2(aq)+NaA2COA3(aq)→BaCOA3(s)+2NaCl(aq)
Which of the following diagrams best represents the mixture after the reaction has proceeded as completely as possible?
