Make a balanced chemical formula
You can find calcium carbonate for purchase at most pharmacies, health food stores, and online retailers.
The carbonate. Calcium is neutral.
To determine the amount of calcium carbonate in limestone, you can perform a titration using hydrochloric acid. By reacting a known mass of limestone with hydrochloric acid, you can measure the volume of acid required to neutralize the calcium carbonate. This information can then be used to calculate the amount of calcium carbonate present in the limestone sample.
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.
There is no oxygen in calcium carbonate. Calcium carbonate is composed of calcium, carbon, and oxygen atoms. The chemical formula for calcium carbonate is CaCO3, indicating that each molecule contains one calcium atom, one carbon atom, and three oxygen atoms.

Powdering calcium carbonate increases its surface area, allowing for more contact with the acid. This increased surface area leads to more frequent collisions between the particles of calcium carbonate and the acid, which accelerates the reaction rate.
What is the product of calcium carbonate
Determining the calcium concentration in the limestone.
Calcium oxide
Ca3P2 or Ca3(PO4)2 See related question below for more details on how to find empirical formulas.
To calculate the mass of calcium oxide that can be produced from 4.7 kg of calcium carbonate, you need the molar masses of both calcium carbonate (CaCO₃) and calcium oxide (CaO). Additionally, you need to know the balanced chemical equation for the decomposition of calcium carbonate, which is: CaCO₃ → CaO + CO₂. Using this information, you can determine the moles of calcium carbonate and then use stoichiometry to find the corresponding mass of calcium oxide produced.
