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.
All of the following statements concerning voltaic cells are true EXCEPT a. a voltaic cell can be used as a source of energy. b. electrons flow from the anode to the cathode in the external circuit. c. a salt bridge allows cations and anions to move between the halfâcells.d. oxidation occurs at the cathode.9.ll of the following statements concerning voltaic cells are true EXCEPT a. a voltaic cell can be used as a source of energy. b. electrons flow from the anode to the cathode in the external circuit. c. a salt bridge allows cations and anions to move between the halfâcells.
