Question

Sapling Learhing An experiment was performed to test the relative activities of four metals, A, B, C, and D. Each solid metal was mixed with solutions of each of the other cations as shown in this chart. The results were indicated as follows A ag B (aq) For example, when A (aq) was mixed with B(s), a reaction occured. Caq D-(aq) Y yes a reaction occured N no a reaction did not occur Use this data to rank the neutral metals according to their activity Most reactive eac There is a hint available! View the hint by clicking on the bottom divider bar. Click on the divider bar again to hide the hint Close

Explanation / Answer

A+ was reduced by B and C but not D

means D is least reactive

A is 2nd last reactive

Answer:

B

C

A

D
