Depends on which weapon you're referring to. Most (but not all) service rifles have a bolt hold open device which keeps the bolt locked to the rear when the last round is fired. The Garand had the ammunition which was loaded into a clip, which was then loaded into a magazine, and that clip would spring out when the last round was fired (although unfortunately it also gave away this fact to the enemy sometimes).
Weapons such as the Kalashnikov do not have any such feature, and you may not know you're out of ammo until your weapons stops firing, or you might grind down the follower stops in the magazine, which will effectively hold the bolt to the rear when the last round is fired (although it will slam back forward once the magazine is removed).
Another prescribed (although not commonly practiced) method is to load three tracers into the magazine first - these will be the last three rounds fired, and will indicate that the weapon is out of ammo. However, this also works both ways, and lets the opposition know you have to stop and reload, as well.
the bolt will remain open
There isn't one, other than that you won't hear the distinctive sound of the next cartridge being ejected from the magazine.
The M500 is the US Navy designation for the Mossberg 590 shotgun, which is a part of the Mossberg 500 family. There is no indication that the last round has been fired, other than hearing just a click and no report when you pull the trigger. This requires the firer to keep track of the rounds they fire.
The bolt will lock to the rear. Look inside the ejection port and make sure the magazine is empty and the chamber is clear; visual verification will be enough.
Since that time covers more than 1000 years, and no one has been keeping count, there is no way to even guess at an answer.
The battle would have been won had we not run out of ammunition for the Howitzers.
None. It's a nonexistent round. There have, however, been reports of 7.62x39 and 7.62x54R rifles and cases of ammunition being misprinted - 7.62x59 is one of the commonly cited dimensions in these misprints.
John cena has been fired but will return
There has been no strong indication that Richard Hammond is an atheist. But, neither has there been overwhelming indication that he is of religious beliefs.
Have the weapon checked by a gunsmith. There is more than one "38" chambering that has been use the past 100 yrs or so.

He hasn't really been fired. It is just a storyline and yes he has returned.
