 It can be seen depending on the size of explosion but not heard as space is vacuum and sound needs a medium to travel.

 exlosion must see first and sound is heard later because the speed of light is more than sound

  a) Seen  because speed of light is 3,00,000 km / per sec. So the explosion on the moon will be seen first.
