It should be dilute hydrochloric acid added to marble, right?
Ok, it is a simple reaction.
Hydrochloric acid reacts with marble, which is made up of calcium carbonate, to form calcium chloride, water, and carbon dioxide.
2HCl(aq) + CaCO3(s) → CaCl2(aq) + H2O(l)+CO2(g)
The carbon dioxide can then be passed to limewater to test (which would turn it into calcium carbonate again)
