Answer 1

Answer:

   MARK ME AS BFAINLIEST

Explanation:

Equal lengths of magnesium ribbons are taken in test tube A and B. Hydrochloric acid(HCL) is added to test tube A, while acetic acid (CH3COOH) is added it,it started fizzing because in both test tube hydrogen gas is formed.

Answer 2

Answer:

please mark me as brainliest please

Fizzing will occur more vigorously in test tube A. Hydrochloric acid (HCl) is a strong acid whereas acetic acid (CH3COOH) is a weak acid. Being strong acid, the hydrochloric acid solution contains a much greater amount of hydrogen ions in it due to which the fizzing will occur more vigorously in test tube A (containing hydrochloric acid). The fizzing is due to the evolution of hydrogen gas which is formed by the action of acid on the magnesium metal of magnesium ribbon.
