How can limestone testing as caco3?
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.
Formula of limestone?
It is CaCO3.....it is the same as marbleFormula: CaCO3
Is caco3 insoluble when react with water?
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 .
Is CaCO3 a reactant or product?
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.
What is the balanced equation for caCO3 2HCI?
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
What is purpose of adding HCl to the CaCO3 -H2O mixture prior to dilute?
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.
What is the grams of substance in 4.5 moles CaCO3?
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.

How do you balance CaCO3 ----- CaO CO2?
the answer is DECOMPOSITION... and that is the answer not CaCO3
What is CaCO3?
CaCO3 is the chemical formula for calcium carbonate.
Is CaCo3 insolube in water?
CaCO3 is insoluble in water.
What will happen after heating CaCO3?
CaCo3=Cao+Co2
How many moles are there in 250 g of CaCO3?
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
What is the mass of CaCO3?
Molar mass of CaCO3 = 100.0869 g/mol
Is CaCO3 a reactant or product?
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.
