A:
The moon has no atmosphere to speak of. (There might be a few molecules
knocked off from time to time by sunlight, but nothing much). So
theres no buoyant force on a balloon, whatever its contents. The
helium balloon will just fall to the moon with the same lunar rate of
gravitational acceleration (about a seventh of that on the surface of
the Earth) as anything else.
If you pop the ballon, the helium will expand into space -- the molecules will go off in all directions. Some will bounce off the surface of the moon and head back the other way.
