Heres a little background knowledge on how NMR works just in case we are asked on the process of a specific spec technique

I made a flow chart for mod 8 Iq1 to help identify which ions are in solution. Hopefully this is helpful

Depends on what the error is & where it occurred. For rinsing the burette with deionised water, the titrant we place in there will be diluted, thus it will have a lower concentration than expected. Thus, more of it will be required to neutralise the titrand, resulting in the tiratnd's calculated...

Perhaps how to perform a titration, and what happens to the calculated value of acid/base if errors occur in the method (like using deionised water to rinse burette)

What module do you guys recon will come up the most tomorrow? My mate from a selective school said Mod 6 & 8

Here it is : https://educationstandards.nsw.edu.au/wps/wcm/connect/ad94ad5f-4f41-449c-abdb-d50aab0f67b9/chemistry-2019-additional-sample-hsc-questions.pdf?MOD=AJPERES&CVID=

Yes, there are many sample responses in HSC papers where they use this form

what paper had the hardest multis, 2021 ?

ight thanks

Surely we don't need to remember the entire structure of a polymer like Nylon 6,6, right? Will they give us a stimulus?

What? There was no graphing question for that

Yeah wth, uv radiation can cause germline? I asked ChatGPT to clarify, im sure if you put your balls in the sun it would :haha:

wait is alignment scaling? Because no way in 2023, a raw mark of 88 only goes to 91 aligned mark

thats makes sense lmao, thats why bio was so easy this year, lets hope 😭

You guys think this year will be a hard paper? Since last year was fairly easy

Wait we need to know everything from year 11? Like galvanic cells

Stoichiometry from calibration curve? Is that even in the syllabus? My school NEVER taught me this

What do you recon is the hardest topic?

Does rank really matter that much, like so what that your rank 1?

Is it really important that we need to know the structure of a nephron (loop of Helene)? It never appears in any HSC exam
