A researcher works out the total numbers of carbon atoms and hydrogen atoms in a sample of propene. All of the propene in the sample then reacts by addition polymerisation to form poly(propene). The researcher works out the total numbers of carbon atoms and hydrogen atoms in the poly(propene) produced.
How do the totals for the poly(propene) compare with the totals for the propene?
The same number of carbon atoms and the same number of hydrogen atoms
The same number of carbon atoms but fewer hydrogen atoms
Fewer carbon atoms but the same number of hydrogen atoms
Fewer carbon atoms and fewer hydrogen atoms
