When a lead acid car battery is recharged by the alternator, it acts essentially as an electrolytic cell in which solid lead(ii) sulfate is reduced to lead at the cathode and oxidized to solid lead(ii) oxide at the anode. suppose a current of is fed into a car battery for seconds. calculate the mass of lead deposited on the cathode of the battery.

7.study the scenario. a small container of water with a low temperature is poured into a large container of water with a higher temperature. which choice correctly explains what happens to the thermal energy of these systems? the smaller container of water has more heat and thermal energy than the larger container. some heat and thermal energy is transferred to the larger container of water. the larger container of water has more heat and thermal energy than the smaller container. some heat and thermal energy is transferred to the smaller container of water. the larger container of water has more thermal energy and some of that energy is transferred to the colder water in a process known as heating. the smaller container of water has more thermal energy than the larger container, and some of that energy is transferred to the warmer water in a process known as heating.
