Lesson 3 Forming a precipitate

The precipitate is calcium carbonate, which is chalk and is also in eggshells, seashells, and coral. Looking at the chemical equation, the products are calcium carbonate, sodium chloride, water, and carbon dioxide. Carbon dioxide leaves the reaction as a gas and sodium chloride dissolves in the water, so the precipitate must be calcium carbonate.
