When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate pbso4 is reduced to lead at the cathode and oxidized to solid lead(ii) oxide pbo at the anode. suppose a current of 96.0a is fed into a car battery for 37.0 seconds. calculate the mass of lead deposited on the cathode of the battery. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol.

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.
