One of the plastics is the addition polymer poly(propene). Complete the equation by drawing the partial structure of poly(propene).
Plastic waste is dealt with by combustion. Construct an equation to show the complete combustion of poly(propene). Use the empirical formula of poly(propene), $\text{CH}_2$, in the equation.
Suggest one advantage of a plastic that is biodegradable.
The partial structure of a condensation polymer is shown. Draw the structure of the monomer from which this polymer is made.
Glass waste is heated until it melts and then shaped into new objects. Use the kinetic particle theory to describe how the movement and arrangement of the particles change when a solid turns into a liquid.
Glass is made from sand, $\text{SiO}_2$. Explain, in terms of structure and bonding, why sand has a high melting point.
