Properties of CaCO3. It is a fluffy powder. It decomposes to give carbon dioxide when heated up to 1200K. When it reacts with dilute acid, it liberates carbon dioxide as a by-product. CaCO3+H2SO4 → CaSO4+H2O+CO2. At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. CaCO3 → CaO + CO2.

Sand (mostly silicon dioxide) is not. Pour the salt and sand mixture into a pan. Add water. Heat the water until the salt dissolves. Remove the pan from heat and allow it to cool until it's safe to handle. Pour the salt water into a separate container. Now collect the sand. Pour the salt water back into the empty pan.
To separate a mixture of silicon dioxide, sodium chloride, and calcium carbonate To determine the mass percent of each component in the original mixture and calculate the total recovery as a percentage of the original shape. Silicon Dioxide. Sand (SiO2)
Since silicon dioxide and calcium carbonate are solids, you can separate the sodium chloride by filtration. Once you separate the aqueous solution of sodium chloride, you can drive off the water by evaporation. After you separate the solids from the aqueous sodium chloride, add the hydrochloric acid to the silicon dioxide - calcium carbonate ...
