Yes, marble fizzes in hydrochloric acid. This is because marble is a type of carbonate rock, and when it comes into contact with hydrochloric acid, the acid reacts with the calcium carbonate in the marble to produce carbon dioxide gas. This gas causes the marble to fizz and bubble.

The chemical equation for the reaction between marble and hydrochloric acid is:

CaCO3 + 2HCl ---> CaCl2 + H2O + CO2

The products of this reaction are calcium chloride, water, and carbon dioxide gas.
