Someone said state ranks are leaked? Would someone be so kind to send a link here

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 😭
