u dont need to do saponification, polymers try the 2019 additional questions if u haven't already they make u write a 7ish marker and their sample ans is half decent

np :) lmk if u need anything else, happy to help 🙏

idk prolly given 2021 was the hardest paper, but the 2019 additional questions has some pretty hard ones

notes from my summary attatched, idk if they'll be of any use but this is normally my approach

Usually reference to the gibbs free formula resulting and the resulting gibbs free value (spontaneous/not) - which is basically same as the table (the one w entropy vs entropy and the boxes state spontaneity) ie combustion of octane (GIVE EQUATION) - enthalpy of combustion is always negative...

syllabus mentions "nylon and polyesters" by name as an example in the same way they do for addition polymers, it specifies MODEL and compare structure, properties and uses of condensation polymers so bare minimum id say remember what types of monomers can be used + the linking functional group...

pretty sure you do, it's not that hard tho the 6 tells u the number of carbons then u js gotta remember it's joined by an amide group

look there's no point in worrying about it now, idk how median has already been predicted given we sat the paper 2 days ago so it is entirely likely it is just rumor, we don't know the marking criteria and we don't know the scaling. It's completely out of your control and whatever happens...

we need to know theory

lowkey id rather it than polymers

nahh my memories good for everything except solubility rules its so annoying, honestly I doubt they'd put a rlly long ion ID thing but they hypothetically could I suppose, we had to draw a flow chart for trials + explain why it identifies 3 ions which was about 5 marks. I feel like they wouldn't...

yeah true, I'm hoping there's time for me to plan out some of my responses for some of the chunkier theory questions bc I'm actually so uncohesive if I don't think about the way I'm phrasing things lmaoo but who knows ig

controversial but i wouldn't say bio was easy easy this yr, I think it was one of those tests where they're gonna mark for specifics that people might of missed for questions that seem relatively easy on the surface but want reference to specific things (like the CFTR question), especially since...

u need to know main principles of precipitation titration (normally using silver, using an indicator with a higher solubility than the precipitate formed, etc) but since the syllabus doesn't specify, you don't technically need to know specific methods for precipitation titrations better safe...

literally praying its actually like this

nah it's assumed knowledge, I've seen gibbs free calculations for determining spontaneity of non equilibrium reaction (m5 - combustion, photosynthesis) in my school's past trial papers but hasn't appeared in the HSC outside of the m5 syllabus

yeah it's in the syllabus, or well it's in 2019 sample questions for mod 8 so kinda in the syllabus at least. See Mod 8 – Question 13, highly recommend doing it since they haven't tested a similar question yet

common sense how though?? we were just given a flow chart I don't see any world where precipitate formation is common sense 💀 if there is an intuitive explanation for it feel free to link something idk Also not taught crystal field theory, idk what extent you get taught content for chem in...

nah I get that, honestly repetition is the only thing that rlly works for titrations - though I know a lot of people who draw diagrams of the procedure to help with the logic of the calculations (like for pre-dilution and all that) and that seems to work this might be the year they give us a...

nahh same i will be so blessed on the day if i can remember ion testing using precipitation, hell even flame test colours
