Use the following information to answer the questions. Electroplating is a widely used process. One of the most popular electroplating processes involves the plating of two metals, nickel and chromium, in separate vats. Nickel is plated first because it adheres better to iron. Next, the object is moved to a second vat in which a layer of chromium is plated. Half-reactions occurring in each vat are shown below: plating of nickel: Ni²+ (aq) + 2 e à Ni(s) plating of chromium: Cr₂O₂(aq) + 14 H*(aq) + 12 e à 2 Cr(s) + 7 H₂O(1) 1. The power supply used in commercial electroplating provides each vat with approximately 1.50 x 10³ A of current for 20.0 minutes. In which vat is the greatest mass of metal deposited on a car bumper? Justify your answer. [547 g, 162 g] Answer:
