# A strip of solid copper, \(\text{Cu(s)}\), is immersed in an aqueous solution of silver nitrate, \(\text{AgNO}_3\text{(aq)}\). A single-replacement oxidation-reduction reaction occurs according to the balanced equation below:

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

A particulate representation of a microscopic section at the solid-solution interface prior to the reaction is shown in the diagram. Solvent water molecules and spectator nitrate ions, \(\text{NO}_3^-\text{(aq)}\), are omitted for clarity.

Which of the following particulate diagrams best represents the same microscopic section after the reaction between \(\text{Cu(s)}\) and \(\text{Ag}^+\text{(aq)}\) has proceeded to completion?

![A rectangular container represents an interface with a solid phase at the bottom and an aqueous solution above. A legend at the top right defines: open circle = \(\text{Cu(s)}\) atom, solid black circle = \(\text{Ag(s)}\) atom, hatched circle = \(\text{Cu}^{2+}\text{(aq)}\) ion, gray-filled circle = \(\text{Ag}^+\text{(aq)}\) ion. The bottom solid region contains a single ordered horizontal layer of exactly 6 open circles. The upper solution region contains exactly 6 gray-filled circles, distributed randomly. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596948-doOvdl.jpg)
