Worked Solution & Example Answer:This question is about polymers - Edexcel - GCSE Chemistry - Question 10 - 2021 - Paper 1
Step 1
State a problem with recycling polymers.
Answer
One problem with recycling polymers is that they often need to be sorted into different types due to their varying properties. This sorting process can be labor-intensive and time-consuming. Furthermore, some polymers cannot be recycled due to their chemical structure.
Step 2
Describe a problem associated with the disposal of polymers.
Answer
A significant problem associated with the disposal of polymers is that they can persist in landfills for an extraordinarily long time. Many polymers degrade very slowly, leading to long-term environmental issues. Additionally, during combustion, these materials can release harmful gases that may pose health risks.
Step 3
Step 4
Draw a section of a poly(chloroethene) molecule containing three repeating units, showing all bonds.
Answer
The structure of a poly(chloroethene) molecule can be represented as follows:
H H H
| | |
H--C--C--C--
| | |
Cl H H
This shows a chain containing three repeating units of the chloroethene monomer with all bonds depicted.
