Worked Solution & Example Answer:This question is about polymers - Edexcel - GCSE Chemistry - Question 4 - 2021 - Paper 1
Step 1
State a problem with recycling polymers.
Answer
One problem with recycling polymers is that it requires sorting them into different types. This can be time-consuming and requires specialized equipment, which may not always be available. Additionally, any contaminants can complicate the recycling process.
Step 2
Describe a problem associated with the disposal of polymers.
Answer
One significant issue with the disposal of polymers is that they often persist in landfills and do not decompose easily. They can take many years to break down, leading to environmental pollution and harm to wildlife. Some polymers may also release toxic gases during combustion.
Step 3
Step 4
Draw a section of a poly(chloroethene) molecule containing three repeating units, showing all bonds.
Answer
The structure of poly(chloroethene) with three repeating units can be illustrated as follows:
H H H
| | |
H-C-C-C-H
| | |
Cl Cl Cl
In this structure, each carbon atom is bonded to two hydrogen atoms and one chlorine atom, forming a linear chain.
