What is Crude Oil made of?
Crude Oil is made of Hydrocarbons, which are compounds called Alkenes. Alkenes contain a single chain of carbon atoms with hydrogen atoms bonded along the side.
1 of 19
Why is Crude Oil a non-renewable resource?
It is made up from the remains of dead plants and animals over millions of years, meaning its not possible to continue using it as we will eventually run out of it, whether it be another million years or forever.
2 of 19
Is Crude Oil a very useful substance?
No, we need to refine Crude Oil because it is unuseful on its own. By refining it, we are changing it so we can use it for things like Petrol and Parrafin.
3 of 19
Name the hottest product and its properties in fractional distillation.
Bitumen; Large Molecules, High boiling point, Not very volatile, Doesn't flow easily, Doesn't ignite easily
4 of 19
Name the coldest product and its properties in fractional distillation.
LPG; Small Molecules, Low boiling point, Very volatile, Flows easily, Ignites easily.

What is does Cracking do?
Cracking allows large Hydrocarbon molecules to be broken down into smaller Alkane and Alkene molecules, smaller Hydrocarbons are more useful as fuels, such as petrols. Also, Alkenes are useful, because they are used to make polymers.
6 of 19
Name the simplest form of Alkane and Alkene and the difference between Alkanes and Alkenes.
The simplest form of Alkane is Methane, with the formula: CH . The simplest form of Alkene is Ethene, which has the formula:C H . The difference between Alkanes and Alkenes is that Alkenes contain at least one double bond between carbon atoms.
7 of 19
Name the formulas for Alkanes and Alkenes.
Alkanes= CnH n+ . Alkenes= CnH n.
8 of 19
How do Alkenes react with Bromine water?
The Bromine reacts with Alkenes in an addition reaction.The double bond of the Alkene breaks, allowing the Bromine to attatch. The Bromine, by reacting with an Alkene, is removed from the solution, meaning the orange-brown colour dissapears.
9 of 19
What are Saturated and Unsaturated compounds? What are some examples of them?
Saturated compounds only contain single covelant bonds. An example of saturated compounds are Alkanes. Unsaturated Compounds contain at least one double bond between Carbon atoms. An example of unsaturated compounds are Alkenes.
10 of 19
What is the word equation for complete combustion?
Hydrocarbon+Oxygen Carbon Dioxide+Water+Energy
11 of 19
Why is Carbon Monoxide dangerous?
It cannot be seen, smelt or tastyed so it can't be easily detected. It reacts with the haemoglobin in red blood cells and reduces their ability of carrying oxygen.
12 of 19
Name the percentages of gas in the air.
Nitrogen= 78%. Oxygen= 21%. Other=1%. Carbon Dioxide= 0.03%.
13 of 19
What is meant by intermolecular forces?
The forces that keep atoms linked together.
14 of 19
What is the realationship betweem molecular size of a Hydrocarbon and the strength of its intermolecular forces?
The longer the molecule chain, and the stronger the intermolecular force= A high boiling point and Rigid plastic
15 of 19
What is the relationship between the strength of intermolecular forces and boiling point?
Stonger forces mean higher boiling points and Weaker forces mean Lower boiling points.
16 of 19
What happens when a sample of Ethene is added to Bromine water?
The Ethene turns the Bromine water colourless.
17 of 19
Name the liquid used to test for Carbon Dioxide.
Limewater.
18 of 19
What does a catalytic converter do?
A catalytic converter reduces the amount of gases produced when driving a car.
