  2. The Name of the Compound: Carbon Dioxide The Formula of the Compound: CO2 The Electron Diagram of the Compound O C O

  3. Physical properties of the Compound 1. Melting point: -78 °C, 194.7 K, -109 °F (subl.) 2. Boiling point: -57 °C, 216.6 K, -70 °F (at 5.185 bar) 3. Physical state at room temperature: Gas 4. Color: Colorless 5. Odor: Odorless 6. Density: 1.562 g/mL (solid at 1 atm and −78.5 °C)0.770 g/mL (liquid at 56 atm and 20 °C)1.977 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 propertiesof the Compound • 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.
