State one benefit and limitation for each route, identify acidic or toxic combustion products and connect finely divided calcium hydroxide to neutralisation and surface area.
This question is about alkenes.
Incinerators used to dispose of polymer waste have a system to remove waste gases.
Suggest why these systems contain solid calcium hydroxide and why it is finely powdered.
An answer that makes reference to the following points:
- solid calcium hydroxide is basic and neutralises/reacts with/absorbs acidic waste gases such as HCl, SOX2, NOx or COX2
- fine powder has a large surface area, ensuring a fast reaction / increasing the rate of reaction
