When a piece of zinc metal is added to a solution of Cu^2+, Zn^2+ appears in solution and a film of copper metal forms on the piece of zinc metal. What does this tell you about the reactivity of the element zinc relative to that of the element copper? Copper metal is more reactive than zinc metal. Zinc metal is more reactive than copper metal. The reactivities of copper metal and zinc metal are approximately equal. No conclusions can be drawn about the relative reactivity of these two elemental metals. When a solution containing I^- is mixed with a solution containing Cl_2, Cl^- and l_2 appear in the solution. What does this tell you about the reactivity of the element chlorine relative to that of the element iodine? Iodine is more reactive than chlorine. Chlorine is more reactive than iodine. The reactivities of chlorine and iodine are approximately equal. No conclusions can be drawn about the relative reactivity of these two elements.
