Firstly, I would like to apologize as there seems to be some confusion. The formula Ca2CO4 does not correspond to any known chemical compound. This formula does not conform to the rules of chemistry because compounds of calcium (Ca) usually have a valency of +2, while carbonate (CO3) has a valency of -2. Hence, the compound calcium carbonate is usually written as CaCO3, not Ca2CO4.
If you are seeking information about calcium carbonate (CaCO3), I would be happy to provide:
CaCO3, also known as calcium carbonate, calcium carbonic, or limestone, is a naturally occurring chemical compound found in various types of minerals such as limestone, marble, and oyster shells. Its molar mass is 100.0869 g/mol.
Physical properties of CaCO3: In its standard state, it is a solid, odorless, white substance that is either insoluble or slightly soluble in water. It has a neutral pH.
Chemical properties of CaCO3: It does not dissolve in water but dissolves in acid, producing CO2 gas. It can also withstand heat to produce CaO (quicklime) and CO2.
Common chemical reactions of CaCO3 include reaction with acid (for example, HCl) to produce CaCl2, H2O, and CO2; thermal decomposition to produce CaO and CO2; reaction with water to produce Ca(OH)2 and CO2.
There are many ways to prepare CaCO3, from heating limestone (thermal decomposition) in a laboratory to extracting the compound from natural sources such as limestone and marble on an industrial scale.
