In the original mixtures, test tube 1 contained magnesium and a zinc compound, and test tube 2 contained zinc and a magnesium compound. A similar relationship exists between test tubes 3 and 4 and between test tubes 5 and 6.
Compare what took place in each corresponding pair of test tubes. What general conclusion can you draw?
