  1. What makes this an oxidation-reaction? 3Ag2S+2Al(s) -> Al2S3+6 Ag(s)?
    Loss and gain of electrons

    Write the half-reactions showing the oxidation and reduction reactions. Identify which is the oxidation reaction and which is the reduction reason.
    oxidation half cell is
    Al ==> Al^3+ + 3e

    Reduction half cell is
    Ag^+ + e ==> Ag
    I have omitted the spectator ions You can add those if you wish.


    What is oxidized in the reaction? What is reduced?
    answered above.

    In this simple electrochemical cell, what functions as the anode? What is the cathode?
    The electrode losing electrons is the anode; the electrode gaining electrons is the cathode.

    Is this a galvanic cell or electrolytic cell?
    This is a galvanic cell since the cell voltage is positive

    What would the overall potential for this cell be?
    I will leave this for you
