Why pop sound is produced when hydrogen is burned?

A lot of energy is released by hydrogen when it combusts. And this gaseous mixture contains hydrogen, oxygen and water vapor liberated from the reaction. This quick expandation of gas molecules causes a break of the sound barrier. And because of this explosion we hear the pop sound of hydrogen burning.

What causes the pop sound to be heard when the matchstick is placed over the beaker with MG and acid?

When magnesium is burned with hydrochloric acid, a pop sound is heard when a glowing splint is brought near the beaker. It is because hydrogen gas is released along with the formation of magnesium chloride and hydrogen gas reignites the glowing splint and is followed by a pop sound.

Why pop sound is produced on bringing a burning matchstick near a test tube containing zinc and HCL?

INFERENCE- Metals react with acids and displaces hydrogen from the acids to produce hydrogen gas and metal salt. If a matchstick is brought near the mouth of the tube containing the product of the reaction then we hear a pop sound. It is this hydrogen gas that burns with a pop sound.

What happens when a burning matchstick is brought near hydrogen gas?

When a matchstick is brought near the mouth of the test tube in which a metal has reacted with sulphuric acid, the matchstick produces a pop-sound nd stops burning. THE POP SOIND MADE IS DUE TO THE EVOLUTION OF HYDROGEN GAS, THEREBY, BURNING OUT THE FLAME.

When a lighted matchstick is applied this gas burns by producing a pop sound?

hydrogen gas
(a) The ‘pop’ sound indicates the presence of hydrogen gas. Metals react with dilute acids to form metallic salts and hydrogen gas.

Which gas makes a pop sound when it exposed to lighted matchstick?

Hydrogen is the gas that makes a distinct ‘pop’ sound when exposed to a small fire of a lighted matchstick. This property is used in the identification of hydrogen in the Burnt Splint test of the gases in the laboratories, as no other gas is ever found to make such a sound on coming in contact with fire.

What do you observe when a matchstick flame is brought near a tube containing hydrogen gas?

Answer Expert Verified. There will be a “pop” sound when a matchstick flame is brought near a tube containing hydrogen gas.

What do you observe when a glowing matchstick is brought near oxygen gas?

Answer Expert Verified We hear a ‘pop’ sound. This is produced Beacuse of the burning of hydrogen.
