The Coke Oven Battery. A Coke Oven Battery consisted of a great many ovens, sometimes hundreds of ovens, in a row. Some mines also employed parallel batteries as in the illustration. Salem Mine No.1 Coke Works, Salemville, PA, used three banks of single ovens, containing 280 bee-hive coke ovens.
Differences Between Voltaic and Electrolytic Cells. -Voltaic cells use spontaneous reactions to produce energy-Electrolytic cells use non-spontaneous reactions that requires energy-Voltaic cells have a negative anode and a positive cathode-Electrolytic cells have a positive anode and a negative cathode.
A voltaic cell differs from an electrolytic cell in that a chemical cell uses 1. half-reactions 2. a solution of ions 3. an applied electric current 4. a redox reaction to produce electricity 15. The diagram shows an electrolytic cell in which the electrodes are tin and copper. The salt bridge prevents the direct mixing of one half-cell solution with the other. C The salt bridge allows electrons to migrate from one half-cell to the other. D The salt bridge allows ions to migrate from one half-cell to the other.
