Discussion and Conclusion - seperation of a mixture

For example, when separating the iron, salt, and sand mixture we were able to use a magnet to remove the majority of the iron from the mixture. This form of physical separation works because even though the components are mixed together, they retain their own characteristics, so iron remained magnetic even though it was a part of the mixture.

Calcium Carbonate (CaCO3) - Uses, Preparation, Properties

Properties of CaCO 3. 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. \(~~~~~\) CaCO 3 +H 2 SO 4 → CaSO 4 +H 2 O+CO 2. At 1200K, calcium carbonate decomposes to give carbon dioxide and calcium oxide. CaCO 3 → CaO + CO 2
