Carbon.
To determine the volume of carbon dioxide needed, you would need to know the stoichiometry of the reaction between carbon dioxide and calcium carbonate. In this case, since 20 grams of calcium carbonate is given, you would convert that to moles using the molar mass of calcium carbonate. Then, using the balanced equation, you can determine the mole ratio between carbon dioxide and calcium carbonate. Finally, using the molar volume of carbon dioxide gas at the given conditions (usually 22.4 L/mol at standard temperature and pressure), you can calculate the volume of carbon dioxide needed.
Powdered calcium carbonate has much more surface area, therefore allowing the acid to access the calcium carbonate much more quickly.

Most carbonate minerals are either calcium carbonate (limestone) or a mixture of calcium carbonate with magnesium carbonate (dolomite). However other metals can also combine with carbonate to produce much rarer carbonate minerals.

Limestone is mostly calcium carbonate. processing the total carbonates in the limestone via titration will work, using an acid such as hydrochloric acid.
One Atom of Calcium, One Atom of Carbon, and 3 Atoms of Oxygen. CaCO3
Carbon.
CaCO3 has 3 oxygen atoms per molecule.
