Data

               Test tube 1                                     Test tube 2

          Magnesium + Sulfuric acid          Magnesium + Acetic acid

             Mg + H₂SO₄                                     Mg + CH₃COOH

a) Test tube 1 will have a more vigorous reaction than test tube 2.

b) Sulfuric acid is a strong acid and Acetic acid is a weak acid.

c)

i.- Sulfuric acid because is a strong acid
