Consider four beakers labeled a, b, c, and d, each containing an aqueous solution and a solid piece of metal. identity the beakers in which a chemical reaction will occur and those in which no reaction will occur.

To identify in what beakers will a reaction occur, we need to know what aqueous solution is in the four beakers. Then, we also need to know what metals are placed inside those beakers. Now, we can analyze which metals might or will react to the solution in the beakers.
