Question

.You are given samples of two metals. magnesium and copper. Suggest any
activity to arrange them in order of decreasing activity.​

Answer 1

by recativity series

Explanation:

as manesium is more reactive then copper so according to this reactivity series :-

Mg>Cu

Answer 2

Answer:Magnesium reacts with oxygen only on heating whereas copper reacts with oxygen on very strong heating. These reactions show that here magnesium is the most reactive metal and copper is the least reactive metal. So, the decreasing order of reactivity is:

Magnesium > Copper.
