Apiece of fe(s) at 25°c is placed into h2o(l) at 75°c in an insulated container. a
student predicts that when thermal equilibrium is reached, the fe atoms, being more
massive than the h2o molecules, will have a higher average kinetic energy than the
h2o molecules. which of the following best explains why the student's prediction is
incorrect?

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Ido not understand.
