Based on the activity series of metals, it can be observed that Magnesium being most reactive is not dispalaced by any metal from it's solution whereas copper being the least reactive is displaced by all the metals from it's solution.
What is the activity series of metals?
The activity series of metals is an arrangement of metals based on their reactivities, from the most reactive to the least reactive.
Based on the activity series of metals, the following will be observed:
Zinc nitrate solution + magnesium metal = Magnesium dissolves and zinc metal is obtained
Zinc nitrate solution + Copper metal = No reaction
Zinc nitrate solution + Iron metal = no reaction
Magnesium nitrate solution + Zinc metal = No reaction
Magnesium nitrate solution + copper metal = No reaction
Magnesium nitrate solution + Iron metal = No reaction
Copper nitrate solution + Zinc metal = Zinc metal dissolves and copper metal is produced
Copper nitrate solution + Magnesium metal = Magnesium dissolves and copper metal is produced
Copper nitrate solution + Iron metal = Iron metal dissolves and copper metal is produced
Iron nitrate solution + Zinc metal = Zinc metal dissolves and iron metal is obtained
Iron nitrate solution + Magnesium metal =Magnesium metal dissolves and iron metal is obtained
Iron nitrate solution + Copper metal = No reaction
