Answer:

Coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.

The main four types of reactions are direct combination, analysis reaction, single displacement, and double displacement. If you're asked the five main types of reactions, it is these four and then either acid-base or redox (depending who you ask).

hope it helps
