Hydrogen gas burns forming water, producing a sound, generally called pop sound.
Hydrogen gas + Oxygen gas (from air) → Water (pop sound)
Acids react with most metals and, when they do, a salt is produced. But unlike the reaction between acids and bases, we do not get water. Instead we get hydrogen gas.
It doesn't matter which metal or which acid is used, if there is a reaction we always get hydrogen gas as well as the salt. However, how quickly the reaction goes depends on the metal used and how high up in the reactivity series it is.
