a. For the electrolysis of molten BaCl2, diagram a cell. Include the direction in which a battery would be placed to power the cell. Write out half-reactions. Label flow of electrons, anode, cathode, indicate what is formed at each electrode (assume electrodes are generic metal). Could this reaction be carried out in aqueous solution? Why or why not (justify numerically). b. 0.67 g of Ag is deposited electrolytically from AgNO3after a certain period of time when subjected to a 12A...

Here is a balanced chemical reaction for the combustion of Glucose: C6H12O6(s) + 6O2(g) -->6CO2(g) + 6H2O(g). Calculate the electrical current a human body experiences from the combustion of 300 grams of glucose per day. (Hint - first fond the moles of electrons transferred in the reaction) Use the equation: mass = (I)(t)/F x (M)/(n) n = moles of e- transferred M = molar mass of glucose I = Current (amps) t = time (s) F = Faraday's Constant mass...

To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A ), which expresses the amount of charge, in coulombs (C ), that flows per second (s ): 1 A=1 C/s Another unit of charge is the faraday (F ), which is equal to a mole of electrons and...
