Final answer:
The reactivity series of the metals Zinc, Magnesium, Iron, and Tin is determined by their relative ease of oxidation in single-displacement reactions. Magnesium is more reactive than Zinc, Iron, or Tin.
Step-by-step explanation:
The reactivity series of the metals Zinc, Magnesium, Iron, and Tin is determined by their relative ease of oxidation in single-displacement reactions. The reactivity series ranks metals based on their tendency to lose electrons. In this case, Magnesium has a greater tendency to be oxidized than Zinc, Iron, or Tin. This means that Magnesium is more reactive than the other metals in the series and will displace them from their compounds in a reaction.
