Primary Battery: A Silver-oxide battery is typically used to power small devices such as a wristwatch. This is a type of primary battery (not rechargeable). A new battery contains 0.5 grams of zinc metal (Zn) and 1.75 grams of silver oxide (Ag20). Assume the battery is completely exhausted after 15,000 hours (all of the limiting reagent has been consumed). Battery reactions: Zn + 20H => Zn(OH)2 + 2e Ag:0 + 2H* + 2e => 2Ag + H20 Determine the following: a) Identify anode and calculate moles of anode material in new battery b) Identify cathode and calculate moles of cathode material in a new battery c) Identify limiting reagent
