In a galvanic cell:

1. A chemical reaction produces electrical energy: This is true. In a galvanic cell, a spontaneous redox (reduction-oxidation) reaction occurs that generates an electric current. The chemical energy of the reactants is converted into electrical energy.

2. Electrical energy produces a chemical reaction: This is false for a galvanic cell. In a galvanic cell, it's the chemical reaction that produces electrical energy, not the other way around. However, the statement would be true for an electrolytic cell, which uses electrical energy to drive a non-spontaneous chemical reaction.

3. Reduction occurs at the anode: This is false. In a galvanic cell, oxidation occurs at the anode. Oxidation is the loss of electrons, and this process takes place at the anode to produce electrons for the electric current.

4. Oxidation occurs at the cathode: This is false. In a galvanic cell, reduction occurs at the cathode. Reduction is the gain of electrons, and this process takes place at the cathode, where the electrons produced at the anode are consumed.
