What will happen if you place egg shells in a beaker of dilute hydrochloric acid?
see, egg shells are just the same as marble , they contain calcium carbonate CaCO3. So when u react CaCO3 with HCl

CaCO3 + HCl --- CaCl2 + H20 + C02

so u will see water(vapor I think) + carbondioxide coming out.
Reply:They will dissolve releasing carbon dioxide.

Edit: not really related but here's a fun one for you. Put a raw egg in a jar of vinegar. The shell will dissolve and leave you with a peeled raw egg. Just remembered that from third grade science.
Reply:The egg shells dissolve.



If there is enough hydrochloric acid in the container, the egg shells completely dissolve, leaving the interior of the egg intact surrounded by its membrane.



The remaining egg swells up a bit as it absorbs water through the membrane.
