Question

When metals react with acids or water then produce
gas.​

Answer 1

Answer:

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.

Hydrogen gas
