As already pointed out, the chemical formula of calcium carbonate is CaCO₃. It's the calcium salt of carbonic acid H₂CO₃. It was long believed that carbonic acid could not exist as a pure compound. However, in 1991 it was reported that NASA scientists had succeeded in making solid H₂CO₃ samples. Carbonic acid is a weak acid that forms when carbon dioxide is dissolved in water. The chemical equilibrium equation is:
CO₂ + H₂O ⇌ H₂CO₃
Calcium carbonate actually is one of the most common chemical compound on our planet found in rocks as limestone, which is a type of sedimentary rock consisting mainly of calcium carbonate. It is also the main component of the shells of marine organisms, snails, eggs and even pearls.
The chemical formula for nitric acid is HNO₃. It is a strong and oxidizing acid and is prepared by reaction of nitrogen dioxide (NO₂) with water:
3 NO₂ + H₂O → 2 HNO₃ + NO
Most commercially available nitric acid has a concentration of 68% in water. When the acid is more than 86% strength, it is often called fuming nitric acid, either red fuming nitric acid, or above 95% HNO₃ white fuming nitric acid. Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals. Some precious metals, like gold and platinum-group metal do not react with nitric acid, though pure gold does react with aqua regia, a mixture of concentrated nitric acid and hydrochloric acid. However, some less noble metals like silver or copper can be easily dissolved by nitric acid. Therefore nitric acid is used in jewelry shops to quickly spot low-gold alloys (< 14 carats) and to rapidly assess the gold purity.
In organic chemistry, nitric acid is used for nitration, e.g. by replacing a hydroxyl group. As such it is very important for the synthesis of many common explosives, such as nitroglycerin (and dynamite) or trinitrotoluene (TNT).

Calcium carbonate reacts with nitric acid to produce calcium nitrate, water and carbon dioxide gas..
CaCO3 + 2HNO3 ===> Ca(NO3)2 + CO2 + H2O
