Consider a simple galvanic cell consisting of two beakers by a salt bridge.One beaker contains a solution of MNO4^-in dilute sulfuric acid and has a Pt electrode.The other beaker contains a solution of Sn²⁺ in dilute sulfuric acid,also with a pity electrode.When the two electrodes are conected by a wire, current flows and spontaneous reaction occurs that is described by the following balanced chemical equation: 2MnO^-_4(aq)+5Sn²⁺_(aq)+16H⁺_(aq)➡2Mn²⁺_(aq)+5Sn⁴⁺_(aq)+8H₂O_(l)For this galvanic cell, a. Write the half-reaction that occurs at each electrode b.indicate which electrode us the cathode and which is the anode c.indicate which electrode is the positive electrode and which is the negative electrode
