A metal M displaces zinc from ZnCl, solution, solution
This shows that
Answer Details
The observation that metal M displaces zinc from ZnCl2 solution shows that M is more electropositive than zinc. Electropositivity is a measure of an element's tendency to lose electrons and form positive ions. In this case, M is able to displace zinc from the solution, which means that M has a greater tendency to lose electrons and form a positive ion compared to zinc. Therefore, option B, "M is more electropositive than zinc," is the correct answer.
