5.11 I can recall how nitrogen oxides are formed in car engines

http://www.youtube.com/watch?v=Tc-tQ9dj9n0

a.       Write the general equation for the combustion of a fuel

Fuel+ Oxygen ----- Carbon dioxide+water+energy

b.      During combustion the nitrogen in air can react to form what gases?

Nitric Oxide, Nitric Dioxide and Nitrous Oxide.

c.       What condition is necessary for this reaction to take place?

Heat (High temperatures) .

d.      In what common object is this condition found?

Car engines.

e.      Why is this condition needed for nitrogen to react?

This condition is needed because it needs to break the triple covalent bond. 

f.        What are the dangers of the products from this reaction?

 Nitric acid is formed when in contact with water, which goes on to create acid rain.

5.10 I can recall the problems associated with incomplete combustion

2.       What are the properties of carbon monoxide?

colorless, odorless an poisonous. 

3.       Explain how carbon monoxide is formed

Fuels + Insufficient oxygen à Carbon monoxide + Water + Energy

4.       Explain why carbon monoxide is poisonous

It attaches onto the hemoglobin, which reduces the amount of oxygen it can carry around the body, resulting in a lack of oxygen which would eventually kill you. 

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

a. What is the trend in boiling point of the fractions?
The fractions nearer to the top of the column have a lower boiling point than the ones at the bottom.

b. Define viscosity (source your definition)
Viscosity is the quantity that describes a fluid's resistance to flow. (physics.info)

c. What is the trend in viscosity of the fractions?
The more viscous fractions are collected nearer to the bottom.


d. What is the trend in colour of the fractions?
As we go down the fractions, the colour of each fraction gets darker.

e. Why is crude oil separated into fractions?
So it can be used, and serve a purpose.

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

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

5.7 describe how the industrial process of fractional distillation separates crude oil into fractions

5.8 I can recall the names and uses of the main fractions obtained from crude oil

5.6 I can recall what crude oil is made from

a.) Define the word Hydrocarbon.
A Hydrocarbon is an organic compound consisting entirely of hydrogen and carbon.

b.)Crude oil is made from a mixture of many hydrocarbons

c.) What is crude oil made from?
Crude oil is made up of decomposed organisms which are millions of years old.

d.)How long does it take to make crude oil?
Around 150 million years.

e.) Where does the energy originally come from?
The Sun.

f.)How is crude oil different from coal?
Crude oil is the result of decomposed animals and plants while coal is the result of decomposed forests (i.e trees and plants) Additionally crude oil is a liquid while coal is a solid.

g.) Crude oil, coal and natural gas are collectively known as fossil fuels.

h.) How is crude oil transported when it is extracted from the ground?
The 2 main ways are by tankers or by use of pipelines.
