  • Carbon Dioxide
    • Dilute acid and Calcium Carbonate
      • Calcium Carbonate (marble chips) put in a flask and HCl is added
        • HCl reacts with calcium carbonate to produce calcium chloride, water and carbon dioxide
          • 2HCl + CaCO3 --> CaCl2 + H2O + CO2
          • CO2 is collected in a gas syringe using downward delivery
    • Thermal Decomposition
      • Heat a metal carbonate
      • Copper (II)Carbonate is a green powder that will thermally decompose to carbon dioxide and copper (II) oxide
        • CuCO3 --> CuO + CO2
    • Fizzy Drinks and Fire Extinguishers
      • Fizzy drinks use CO2 so they can fizz. CO2 slightly soluble so dissolves in water when under pressure to form carbonic acid
        • CO2 + H2O --> H2CO3
      • Fire Extinguishers use CO2 as it is more dense than air so sinks onto the flame stopping oxygen getting to it
        • Only used when water extinguishers are not safe
    • Greenhouse Gas and Links with Climate Change
      • The more CO2 in the atmosphere the more heat gets radiated back to earth
      • Deforestation leads to less CO2 being removed from the atmosphere
      • carbon that was 'locked up' in fossil fuels are now being released
      • the extra carbon dioxide in the air has lead to an increase in the earths temperature
