2
Q
How do you crack an alkane?
A
You pass the alkane vapour over a heated catalyst (THERMAL DECOMPOSITION)
3
Q
Define POLYMERISATION
A
Many alkene molecules link together to make a very long polymer molecule
4
Q
Why is disposal of polymers a problem?
A
Because they are not biodegradable
5
Q
How can you make a polymer break down more easily?
