# A galvanic cell is constructed using copper and silver half-cells under standard conditions, as represented in the diagram.

\[ \text{Cu}(s) + 2\,\text{Ag}^+(aq) \rightarrow \text{Cu}^{2+}(aq) + 2\,\text{Ag}(s) \]

After the circuit is closed, the cell operates until a total of \(4\) electrons have passed through the external wire. Which of the following particulate diagrams best represents the solution contents of the two half-cells at this point? (Water molecules and spectator ions are omitted for clarity.)

![A grayscale schematic of a galvanic cell with two separate beakers connected by an inverted U-tube salt bridge and an external wire with a circular voltmeter meter. A legend at the top right maps: an open circle represents \(\text{Cu}^{2+}\), and a solid black circle represents \(\text{Ag}^+\). The left beaker contains a submerged solid rectangular electrode labeled \(\text{Cu}\) and exactly \(2\) open circles distributed throughout the liquid. The right beaker contains a submerged solid rectangular electrode labeled \(\text{Ag}\) and exactly \(6\) solid black circles distributed throughout the liquid. The external wire connects the top of both electrodes through the voltmeter. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787459035-Dhd9ub.jpg)
