----> HC2H3O
Explain the difference observed!
----> Mg/HCl-- melting slower than HC2H3O
----> Mg/HC2H3O-- melting more faster than HCl.

Please check these answers are correct, and Please give me more explain for difference observed.

Thanks

Did you do the experiment?

CH3COOH (acetic acid, or ethanoic acid) is a weak acid.
HCl is a strong acid.

Now, to explain why is that so will require much more to learn.

Ethanoic acid is found in vinegar. I don't think that people will use a strong acid in food. However, you have HCl in bleaching agents, to remove stains that go difficultly with water alone.

From there, can you try?

Ohh so, HCl is vigorously with the Mg right?

Yes, you'll see more bubbles coming out.

If you really did the experiment, I guess you must have interchanged your reactants.
