  2. About Combustion All organic compounds contain carbon. All produce CO2 if burnt in air or O2. Steam is also produced. If the amount of O2 is limited CO main form instead of CO2. ethanol burning Flames can be luminous or non-luminous Ethanol does not produce any soot or smoke Benzene and other aromatic compounds can produce lots of soot! (and have luminous flames) Why are they different?

  3. About Combustion Why are they different? Calculate their % C ethanol burning % C = mass of carbon/total mass x 100% C6H6 C2H5OH

  4. Which of these would produce the greatest amount of soot burning? a C8H18 b CH3CHO c CH3COOC2H5 d C5H11OH
