Resumo de Recurso

Carbon Dioxide
  1. even though it takes up less than 1% of the air it has vital importance
    1. carbon dioxide is produced when carbon is burned in oxygen gas
      1. the word equation is; calcium carbonate + hydrochloric acid = calcium chloride + water+ carbon dioxide
        1. CaCO3 + 2HCL = Cacl2 + h2o +co2
    2. you can test for the presence of co2 using limewater
      1. limewater + carbon dioxide = chalk + water
        1. Ca(OH)2 + CO2 = CaCO3 +H2O
      2. physical properties
        1. colourless, odourless, tasteless gas
          1. slightly soluble in water
            1. more dense than air
        2. chemical properties
          1. does not support combustion
            1. turns limewater milky
              1. dissolves in water to form carbonic acid
          2. uses of carbon dioxide
            1. fizzy drinks
              1. fire extinguishers
                1. refrigeration
                  1. special effects on stage ( dry ice )
