It was a good paper.
Yes there was a lot of memorisation but it doesn't make it a crap paper.
They all relate to chemistry.
For example,
You're meant to know all your experiments so the emulsion one is a valid question.
You should know the production of sodium carbonate and sodium hydroxide in details. If you know them well you can work out the locating the industrial plants one.
Sodium carbonate is produced using Solvay process and the syllabus specifically mention Solvay process in the related dot point.
Although it doesn't mention NaOH, there is another dot point where you need to assess the technical and environmental difficulties of the diaphragm, membrane and mercury processes. You can use this to appropriately select the location of the plants.
