Across
  1. 2. A conductor through which electric current enters or leaves an electrolyte.
  2. 9. An electrochemical cell that uses electrical energy to drive a non-spontaneous chemical reaction.
  3. 10. The deterioration of a metal due to a chemical reaction with its environment.
  4. 11. The electrode where reduction occurs, and electrons are gained in an electrochemical cell.
  5. 12. The process of coating an object with a layer of metal using electrolysis.
Down
  1. 1. The study of the interchange of chemical and electrical energy.
  2. 3. A chemical reaction involving both oxidation and reduction processes.
  3. 4. The loss of electrons by a substance during a chemical reaction.
  4. 5. The gain of electrons by a substance during a chemical reaction.
  5. 6. An electrochemical cell that converts chemical energy directly into electrical energy by combining a fuel (e.g., hydrogen) with an oxidizing agent (e.g., oxygen).
  6. 7. A substance that conducts electricity when dissolved in water or in a molten state.
  7. 8. The electrode where oxidation occurs, and electrons are released in an electrochemical cell.
