The vapor of acetic acid will go to the floor of the room.
This is because the density of acetic acid vapor is equal to 2.07 is higher (almost twice) than the density of air which is equal to only 1

No reaction would occur because copper is more active than silver and silver would be unable to donate electrons to copper.
I believe the answer is a. A passive prosthesis
Prosthesis is used to replace a part of the patient. Some prosthesis powered by external source that allow it to do some degree of movement. Passive prosthesis doesn't have electronic or mechanic part, which makes their function is more to be cosmetic than function.
