A sample of waste includes plastic and copper.

1. (a)One of the plastics is the addition polymer poly(chloroethene). Complete the equation to show the formation of poly(chloroethene). [Figure 9.1][2]
2. (b)(i)Plastic waste is disposed of by combustion. (i) Complete the equation to show the complete combustion of poly(chloroethene). The empirical formula of poly(chloroethene), C2H3Cl, is used in the equation. C2H3Cl + ...........................O2 → ...........................CO2 + ...........................H2O + ...........................HCl[1]
3. (b)(ii)Suggest why the combustion of poly(chloroethene) will contribute to the formation of acid rain.[1]
4. (c)(i)Some waste plastics, such as nylon, are polyamides. (i) Give one large scale use of nylon.[1]
5. (c)(ii)The structure shows a monomer that can be used to make a polyamide. [Figure 9.2] Draw the partial structure of this polyamide. Show two repeat units.[1]
6. (d)Copper waste is melted and then cooled to make new objects. Use the kinetic particle theory to describe the changes in movement and arrangement of the particles when a liquid cools to become a solid.[2]
7. (e)Explain, in terms of structure and bonding, why copper has a high melting point.[2]
