Question

What happens when a burning matchstick is brought near the mouth of gas jar filled with hydrogen gas?

Answer 1

Hydrogen:

• Hydrogen is a chemical element having an atomic number equal to one.
• It was discovered by Henry Cavendish.
• It is a gas with no color and odor and has the lowest density of all gases.
• It is a highly inflammable gas.
• It exists in the diatomic form in nature so 2 atoms of hydrogen make one molecule H₂.

And, When a burning matchstick is brought near the mouth of a gas jar filled with hydrogen gas, then hydrogen gas burns with a squeaky pop sound.

The ‘pop’ is the sound of a small explosion and hydrogen is recognized by the ‘pop’ when it burns.
