Challenge When copper wire is placed into a silver nitrate solution $\left(\mathrm{AgNO}_{3}\right),$ silver crystals and copper(ll) nitrate $\left(\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}\right)$ solution form. \begin{equation} \begin{array}{l}{\text { a. Write the balanced chemical equation for the reaction. }} \\ {\text { b. If a } 20.0 \text { -g sample of copper is used, determine the theoretical yield }} \\ {\text { of silver. }} \\ {\text { c. If } 60.0 \text { g of silver is recovered from the reaction, determine the }} \\ {\text { percent yield of the reaction. }}\end{array} \end{equation}
