Which substance is produced in the reaction between nitric acid and calcium carbonate?

The reaction between nitric acid and calcium carbonate produces calcium nitrate as a key product. When calcium carbonate (CaCO₃) reacts with nitric acid (HNO₃), it undergoes an acid-base reaction, resulting in the formation of calcium nitrate (Ca(NO₃)₂), carbon dioxide (CO₂), and water (H₂O).

Calcium nitrate is a soluble salt that is commonly found in various fertilizers and is significant in agricultural applications. The process involves the calcium ion (Ca²⁺) from calcium carbonate combining with the nitrate ions (NO₃⁻) from nitric acid, leading to the creation of calcium nitrate.

The other substances listed, such as calcium hydroxide, calcium chloride, and calcium sulfide, do not arise from this specific reaction with nitric acid and calcium carbonate. Calcium hydroxide is usually formed from the reaction of calcium oxide with water, calcium chloride is produced from the reaction of hydrochloric acid with calcium carbonate, and calcium sulfide involves a reaction with sulfur compounds.
