What Is The Chemical Formula For Limestone And Marble

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

What is the chemical formula for limestone and marble.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. When limestone is heated and has pressure put on it its calcite is melted. 38 42 lime cao 20 25 silica sio2 2 4 alumina al2o3 1 5 2 5 various oxides nao and mgo and 30 32. That s to say a limestone that has been subject to exceptional heat or pressure.

Stone surface material may be lost all over or only in spots that are more reactive. Chemical formula for marble is caco3. If limestone is pure you get a white marble. Here it means 1 calcium 1 carbon and 3 oxygen.

The chemical formula for calcium carbonate is caco3. Marble is a metamorphosed limestone. Marble is made of calcium carbonate caco3 which is also what limestone is made from. Calcite has the chemical formula caco3 calcium carbonate.

When sulfurous sulfuric and nitric acids in polluted air and rain react with the calcite in marble and limestone the calcite dissolves. They also call marble as calcium carbonate. The only difference between limestone and marble is the crystalline structure. Larger crystals are formed and this is marble.

Sandstone has no defined chemical formula. Typically marble is composed of the following major constituents. Marble is composed primarily of the mineral calcium carbonate modified to crystalline form by metamorphism of the parent limestone. In exposed areas of buildings and statues we see roughened surfaces removal of material and loss of carved details.

The chemical formula for calcium magnesium carbonate is camg co3 2. If it has hematite or clay in it you will get a reddish color marble. Both marble limestone are composed of the mineral calcite. Whatever is mixed in with the limestone decides the final color of the marble.

Pure limestone is made up of two component minerals. The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization.
