D. (30 points) Electrochemistry. One type of battery that has high energy density is the "zinc-air" battery, which is usedin size and weight-sensitive applications such as hearing aids. It uses

solid zinc particles as one electrode, and carboncovered by a gas-permeable (but water impermeable) Teflon membrane. (a) Write the half-reaction that is most likely to occur for Zn in the battery, state whether it is oxidation or reduction,and give the name of the electrode at which it occurs. (b) The reaction at the otherelectrode consumes oxygen from the air, and water from the electrolyte in a basic solution.Write the half-reaction, state whether it is oxidation or reduction, and give the name of the electrode at which itOccurs. (c) Use the provided tables of data to evaluate the cell voltage under standard conditions and 25°C.
