    Answer: Magnesium displaces copper from the solution of its salt (CuSO4)

    Explanation:

    Magnesium + copper sulphate → magnesium sulphate + copper

    Mg (s) + CuSO4 (aq) → MgSO4 (aq) + Cu (s)

    The balanced equation above is a displacement reaction because the more reactive magnesium metal displaces copper from its solution of its salt (CuSO4) due to its higher position in the reactivity series, hence Magnesium forms its own salt solution (MgSO4) while Copper is released in free form (Cu)
