as used in class.... :)

1. Draw the Fire Triangle

2. What are Fuels ?

3. Fuels
• What do fuels need to burn ?
• If I burn a hydrocarbon what do I make ?
• Fuel is any material that stores energy that can
later ...
• If I burn an alcohol what do I make ?

4. Oxygen
• Uses :-
• Welding
• medicine

5. Fossil Fuels
• List 5 fossil fuels
• What are products of combustion ?
• What other gases can be made ?

6. Comparing Fuels
Take 1 candle and record the mass.
Measure 100mls of water in to a glass beaker.
Burn the candle for 2 minutes beneath the water
beaker.
Record the new mass of candle.
Record the temperature rise.

7. Global Warming

8. Starter
• Using the blog find the fractional distillation
column – you have two minutes to remember the
order of products.

9. Alkanes
• Saturated
• Single bonds
• CARBON ALWAYS HAS FOUR BONDS !

10. Alkenes
• Unsaturated
• Double Bonds
• CARBON ALWAYS HAS FOUR BONDS

11. Bromine Water Test
• Bromine reacts with double bonds only.
• If there are double bonds it changes from red to
colourless

12. Friday Starter
• 5 fossil fuels
• 4 alkanes
• 3 alkenes
• 2 uses for crude oil
• 1 reason to be cheerful

13. Starter

14. 14.3 Hydrocarbons
• Alkanes are generally used for energy via the process
of combustion.
• The products with EXCESS Oxygen is ALWAYS
• The products with insufficient Oxygen is ALSO
• Why is this bad for life ?

15. Cracking
• Is the process of breaking large hydrocarbon
molecules into smaller useful alkanes and
alkenes. These alkenes can be chemically altered
further to produce more useful chemicals, e.g.
plastics.
• (Blog review)

16. Start 
• 5 products from the fractional distillation column
• 4 uses of alkenes
• 3 names of plastics
• 2 products of incomplete combustion
• 1 reason to like Thursday

17. Homologous Series
• Differs by one CH2 unit
• Similar chemical properties
• Gradation of physical properties

18. Ethene Reacts with
• Hydrogen
• Bromine
• Steam

19. Alcohols
• Complete combustion
• Solvent
• Fuel

20. Experiment
• Which produces most energy per gram ?
• Which produces most energy per mole ?
• What is the balanced equation for the combustion
of each alcohol ?
• Is it possible that combustion is incomplete ? if so
what are the dangers of this ?

21. Starter
• Write the balanced equation for the complete
combustion of ethanol.
• Write the formula for the first 3 alkenes and name
them 

22. Macromolecules
• Monomers – this is a small molecule that can
bond to other monomers to make a polymer.
• There are two types of monomers – those with a
double bond and those with two functional groups
the same in the same molecule.
• Polymer means many monomers bonded
together.
• We can have addition polymerisationor condensation
polymerisation.

23. Addition Polymerisation
• Ethene
• Propene
• Chloroethene

24. Condensation Polymerisation
• 1,6-diaminohexane with Hexane-1,6-dicaboxylic
acid

25. Nylon Rope
• Condensation polymerisation
