The gas that evolves when dilute hydrochloric acid (HCl) reacts with metals is Hydrogen gas (H2). The reaction also forms the corresponding metal chloride. Here's the step by step process:

1. When a metal reacts with dilute HCl, the metal replaces the hydrogen in the HCl, forming a metal chloride and releasing hydrogen gas.

2. For example, if the metal is zinc (Zn), the reaction would be: Zn + 2HCl - ZnCl2 + H2.

3. In this reaction, zinc chloride (ZnCl2) is the metal salt that is formed, and hydrogen (H2) is the gas that is evolved.

4. This is a type of single displacement reaction, where one element is replaced by another in a compound.

5. The exact metal salt formed will depend on the specific metal that is reacting with the hydrochloric acid.
