Question

Why do we get pop sound in a reaction when we burn matches near it ?❔

Answer 1

Answer:

Hydrogen gas is released when metal reacts with a base. A lighted wooden splint goes pop if it is put into a test tube of hydrogen. This is because the flame ignites the hydrogen, which burns explosively to make a loud sound.

• The fire on the matchstick ignites the hydrogen-oxygen mixture, which burns explosively rapidly. The pop is the sound of the rapidly expanding water vapor and heated hydrogen, slamming into the surrounding air.
