    The answer is in the explanation

    Explanation:

    Single displacement reactions: In these reactions, a more reactive element kicks out a less reactive element from a compound.

    Ex. Zn (s) + 2 HCl (aq) → ZnCl2 (aq) + H2 (g)

    In this example, Zn is more reactive than H, then Zn displaces H from the compound.

    Double displacement reactions: In these kind of reactions 2 elements are displaced from the different compounds, these elements interchange positions.

    Ex. CuCl2 (aq) + 2 AgNO3 (aq) → Cu (NO3) 2 (aq) + 2 AgCl (s)

    In the example, Cu displaces Ag and Ag displaces Cu, they interchange positions.
