1. In the electrolysis of molten sodium chloride,

Question

sodium metal is produced at the anode & chlorine gas at the cathode
sodium ions are produced at the cathode & chloride at the anode
sodium ions are produced at the anode & chloride at the cathode
sodium metal is produced at the cathode & chlorine gas at the anode ***

2.An electrolytic cell can be used to
generate electricity
store electricity
make a battery
electroplate an object that conducts electricity***

3. A non-rechargeable battery won't recharge. This must be because...
as it's used, the chemicals inside it disappear***
it can't conduct electricity
a non-soluble product forms while it is used
non-rechargeable batteries don't have a salt bridge

4.To determine the useful energy available in a voltaic cell, use this formula:
∆G=-nFE
E=E°-(RT/nF)lnQ***
E=E°-0.0592/nlogQ
W=J/s

Answer 1

I agree with your answers to 1 and 2. I think your choice for 3 is the best one available but I don't like the wording about chemicals disappearing. They change into other forms but they don't really disappear. I don't agree with your choice for 4. Your choice (that's b) calculates volts. Choice c is the same thing because [RT/nF*ln] Q converts to [0.0592/n*log] Q. Delta G is the useful work of a system.
