Chalk is calcium carbonate, CaCO3 and acid contains H+. So, using HCl as an example of the acid being used, the chemical reaction would be CaCO3 + 2HCl ==> CaCl2 + CO2 + H2O and the bubbles are formed by the CO2 (carbon dioxide) gas being produced.

Would bubbles appear when acid is added to calcium carbonate?
Yes, carbon dioxide - CO2.

Why are fossils not found in chalk?
Chalk is a fossil itself and chalk is soft, and so while you might form a fossil; in it, it would not remain. Within chalk there is often harder rock - which sometimes does contain fossils.
How do you separate a suspension of chalk in water?
