Chromium plating is applied by electrolysis to objects suspended in a dichromate solution, according to the following half-reaction: Cr,O (ag) + e + H (aq) – Cr (s) + H,O () Detemine the time (in hours) it would take to apply a chromium plating 1.0x102 mm thick to a car bumper with a surface area of 0.25 m in an electrolytic cell carying a current of 25.0 A. (The density of chromium is 7.19 g/em'.)
