DANGERS OF INCOMPLETE
COMBUSTION
COMPARING COMBUSTION
Complete graphing your data from the last
experiment page 227 SciPad.
 Answer the questions page 227.

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.

Remember the possibilities for combustion equations.

Fuel + oxygen = carbon dioxide + water (complete combustion)

Fuel + oxygen = carbon + water (incomplete combustion

Fuel + oxygen = carbon monoxide + water (incomplete

Fuel + oxygen = carbon monoxide + carbon + water
producing soot)
combustion producing toxic gas)
(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.

 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.

WRITING PARAGRAPH STYLE ANSWERS
1.
Underline the main points of the question
Outline how global warming might affect the area
you live in.
2. Plan the key points you need to include in your
writing.
3. Link your points together to form paragraphs
using because, therefore, in contrast to, etc
4. Include a conclusion/summary sentence.
