Assume that a circuit similar to that in figure 2 is set up in which x = al, xn+ = al3+, y = cu, and ym+ = cu2+. which of the following reactions will occur? a.2al3+(aq) + 3cu(s) → 2al(s) + 3cu2+(aq) b.3al3+(aq) + 2cu(s) → 3al(s) + 2cu2+(aq) c.2al(s) + 3cu2+(aq) → 2al3+(aq) + 3cu(s) d.3al(s) + 2cu2+(aq) → 3al3+(aq) + 2cu(s) solution: the correct answer is c. this is a general chemistry question that falls under the content category “atoms, nuclear decay, electronic structure, and atomic chemical behavior.” the answer to this question is c because this response depicts the balanced chemical reaction that occurs when the four substances [al(s), al3+(aq), cu(s), and cu2+(aq)] are mixed. it is a scientific reasoning and problem solving question because you are asked to bring together theory and observations to draw a conclusion.
