A student makes this statement about addition polymerisation.
'When ethene forms poly(ethene), water is given off as well as the polymer.'
The student's statement is wrong. Give the reason why.
Explain why the repeating unit of poly(ethene) contains the same atoms as an ethene molecule.
One poly(ethene) molecule is made from 2000 ethene molecules. Give the number of carbon atoms in this poly(ethene) molecule.
