One of the plastics is the addition polymer poly(chloroethene). Complete the equation to show how poly(chloroethene) is formed.
Plastic waste is eliminated by combustion. Complete the equation to show the complete combustion of poly(chloroethene). Use the empirical formula of poly(chloroethene), C$_2$H$_3$Cl, in the equation. $\dots\dots\dots\ \text{C}_2\text{H}_3\text{Cl} + \dots\dots\dots\ \text{O}_2 \rightarrow \dots\dots\dots\ \text{CO}_2 + \dots\dots\dots\ \text{H}_2\text{O} + \dots\dots\dots\ \text{HCl}$
Suggest why burning poly(chloroethene) will contribute to acid rain formation.
Some waste plastics, such as nylon, are polyamides. Give one large-scale use of nylon.
The structure shows a monomer suitable for making a polyamide. Draw the partial structure of this polyamide. Show two repeat units.
Copper waste is melted and then cooled to make new objects. Use the kinetic particle theory to describe how the movement and arrangement of the particles change as a liquid cools and turns into a solid.
Explain why copper has a high melting point, using structure and bonding.
