1 (10-11) F3 Chemistry Individual Project Work Ionic & Covalent compounds Silvia Chan (2) F. 3C CO2

2 The Name of the Compound: Carbon Dioxide The Formula of the Compound: CO2 The Electron Diagram of the Compound OCO

3 Physical properties of the Compound 1. Melting point: -78 °C, K, -109 °F (subl.)subl. 2. Boiling point: -57 °C, K, -70 °F (at bar) 3. Physical state at room temperature: Gas 4. Color: Colorless 5. Odor: Odorless 6. Density: g/mL (solid at 1 atm and −78.5 °C) g/mL (liquid at 56 atm and 20 °C) g/L (gas at 1 atm and 0 °C) 7. Solubility in water: 1.45 g/L at 25 °C, 100 kPa 8. Electrical Conductivity: Cannot Conduct Electricity

4 Chemical properties of the Compound 1.Laboratory preparation: CO2 is not very harmful because it is not toxic or flammable. If you have to do experiment which require a lot of CO2, then you may have to wear mask to prevent taking too much of it into body, or do in the fume cupboard. Also open windows for better ventilation.

5 Others: 1. Uses: Fire extinguisher Refrigerant Beverages (e.g. Coca Cola) 2. Potential hazards: Nil 3. CO2 is one of the greenhouse gas. 4. There are 0.039% CO2 in the air.
