Context: a student conducted an experiment where they used different masses of Mg powder and mixed each mass w a solution of copper (II) sulfate and then measured the temperature increase. Question: State and explain the effect on the temperature rises if the student were to repeat the experiment using the same masses of zinc powder instead of the magnesium powder.

Do not refer to the difference in reactivity of the two metals.
[relative atomic masses: Mg = 24 ; Zn = 65]

(I'm assuming this has something to do with the ΔH = q/n equation??)
