Answer
One problem with recycling polymers is that they often need to be sorted into different types before they can be processed. This sorting can take time and must be done carefully to separate the polymers based on their chemical composition.
Step 2
Describe a problem associated with the disposal of polymers.

Answer
Polymers pose a significant problem when disposed of in landfills, as they can persist for a long time without breaking down. This slow degradation can lead to environmental concerns, as polymers can remain in the environment for hundreds of years, potentially causing harm to wildlife and ecosystems.

Answer
In the molecule of chloroethene, the functional group is the C-Cl bond. Circle the carbon atom that is bonded to a chlorine atom (C-Cl) in Figure 20.
Step 4
Draw a section of a poly(chloroethene) molecule containing three repeating units, showing all bonds.

Answer
A section of a poly(chloroethene) molecule with three repeating units can be illustrated as follows:
H H H
| | |
H-C-C-C-
| | |
Cl H H
This structure shows a chain of three carbon atoms with single bonds between them, and each carbon is bonded to the appropriate hydrogen or chlorine atoms.
