so, the other day at work, we were sharing riddles and one guy asked this one:

if you fired a gun on the moon, how far would the bullet go.


his answer was nowhere. a gun wont fire on the moon, because you need oxygen for the combustion to take place, and the moon has no atmosphere, thus the gun wont fire.


to which I replied, that if the bullet makes a positive (ie airtight) seal with the shell casing, then the oxygen that is already in there would allow it to fire.


then I got to thinking, does gunpowder require oxygen in order to burn? I know that some elements/chemicals do not, but what about gunpowder?
