To test limestone for its calcium carbonate (CaCO3) content, you can use an acid test. By adding a few drops of dilute hydrochloric acid to a sample of limestone, a reaction will occur if it contains calcium carbonate, producing bubbles of carbon dioxide gas. The intensity of the reaction can indicate the purity of the limestone.
It is CaCO3.....it is the same as marbleFormula: CaCO3
caco3 is solid form. its density is high so caco3 is not soluble in water. but co2 mix in water befuor the mix in caco3 . so caco3 is soluble after mixing the co2 .
CaCO3, calcium carbonate can be either a reactant or a product. If it comes at the beginning of a reaction, then it is a reactant. If it comes at the end of the reaction, then it is a product.
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
Adding HCl to the CaCO3 - H2O mixture prior to dilution helps dissolve the calcium carbonate by reacting with it to form calcium chloride, water, and carbon dioxide. This step is done to increase the solubility of calcium carbonate and facilitate its removal in subsequent steps.
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.

the answer is DECOMPOSITION... and that is the answer not CaCO3
CaCO3 is the chemical formula for calcium carbonate.
CaCO3 is insoluble in water.
CaCo3=Cao+Co2
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
Molar mass of CaCO3 = 100.0869 g/mol
CaCO3, calcium carbonate can be either a reactant or a product. If it comes at the beginning of a reaction, then it is a reactant. If it comes at the end of the reaction, then it is a product.
