5.10 I can recall the problems associated with incomplete combustion

Highlight the spaces below the questions for the answers

1.       What are the properties of carbon monoxide?

colourless, odorless, poisonous gas

2.       Explain how carbon monoxide is formed

incomplete combustion, insufficient oxygen

3.       Explain why carbon monoxide is poisonous

sticks to hemoglobin and doesn't detach itself when delivered to the muscles

5.9 I can describe the trend in boiling point and viscosity of the main fractions

Highlight the spaces below the questions for the answers

a.       What is the trend in boiling point of the fractions?
The higher in the fractionating column the lower the temperature

b.      Define viscosity (source your definition)
The state of being thick, sticky (http://en.wikipedia.org/wiki/Viscosity)

c.       What is the trend in viscosity of the fractions?
The higher in the fractionating column it is the lower the resistance

d.      What is the trend in colour of the fractions?
The higher in the fractionating column the lighter the liquid gets

e.      Why is crude oil separated into fractions?
Crude oil has no beneficial use on its own.

f.        What process is used to separate crude oil into fractions?
Fractional distillation

g.       What physical property allows this process to work?
The boiling points of the different fractions
