Limestone is a sedimentary rock composed largely of the minerals calcite and/or aragonite, which are different crystal forms of calcium carbonate (CaCO3).

Lithographic limestone is primarily composed of calcium carbonate (CaCO3), with small amounts of clay minerals and organic matter. These impurities can affect the color and texture of the stone, making it suitable for lithographic printing.
The fizzing of limestone when acid is added is a chemical change. This is because a chemical reaction occurs between the acid and the calcium carbonate in the limestone, resulting in the production of carbon dioxide gas.
Chemical limestone is synthetic and manufactured through chemical processes, often for specific industrial applications. Organic limestone, on the other hand, forms naturally from biological sources like shells and coral reefs, and is often used as a building material or in agriculture for soil improvement. Organic limestone may contain impurities from its natural formation, while chemical limestone can be tailored for specific composition and properties.
The reaction of acid on limestone to produce carbon dioxide gas is a chemical change. This is because new substances with different properties (carbon dioxide gas and water) are formed during the reaction, changing the chemical composition of the limestone.
The Chemical name for limestone is Calcium Carbonate - CaCO3
Limestone is a type of rock that can be either chemical or organic in nature. Chemical limestone is formed through the precipitation of calcium carbonate, while organic limestone is made up of the remains of marine organisms like shells and coral.
