Question

A piece of magnesium and a piece of charcoal is put in two separate beakers. To each (2)beaker 5 mL of hydrochloric acid is added. A lit matchstick was brought close to the mouth of the beakers. The burning matchstick extinguishes with a pop sound when placed over the beaker with magnesium and acid but not when placed over the beaker with charcoal and acid. What comparison can be drawn between magnesium and charcoal?

Answer 1

Answer:

can you please explain briefly

Answer 2

The magnesium reacts with Hydrochloric Acid and releases hydrogen gas which extinguishes the matchstick with a pop sound.

While in case of charcoal, it reacts with HCl to form calcium chloride, carbon dioxide and water. This doesn't affect the burning matchstick.

Hope this helps you.
