SOOT (CARBON) AND CARBON MONOXIDE
Carbon particles can affect the lungs causing respiratory problems.
Carbon monoxide gas is colourless, odourless and very toxic. It competes with oxygen for the
haeomoglobin
in the bloodstream.
What is haemoglobin?

WORD EQUATIONS – page 229
Remember the possibilities for combustion equations.
Fuel + oxygen = carbon dioxide + water
(complete combustion)
Fuel + oxygen = carbon + water
(incomplete combustion producing soot)
Fuel + oxygen = carbon monoxide + water
(
incomplete combustion producing toxic gas)
Fuel + oxygen = carbon monoxide + carbon + water
(incomplete combustion producing soot + toxic gas)
Read the questions carefully and decide if they are showing complete or incomplete combustion then decide what is produced by the reaction.Slide5

Using the information in the table on page 232 graph the data as two separate lines on your graph. One uses the vertical axis on the left, the other the vertical axis on the right.
Answer the questions on page 234 using the graph you have drawn. We will go over questions 5 and 6 as a class.Slide8
