What happens when a metal reacts with an acid?

• The metal displaces hydrogen from the acid, forming a salt and releasing hydrogen gas.

• The metal and acid combine to form a new substance.

• The acid dissolves in the metal, forming a new acid compound.

• The metal dissolves in the acid, forming a new metal compound.

What are the products formed when a metal reacts with an acid?
