also, how would you test for ketones and aldehydes? I have come across contradicting sources, so it would be amazing if someone can confirm this!

^^^^^ Just for safety!!!

seems right

nah no way 2021 was harder. At least bare minimum it was on par. So I would guess alignment would have to be equal if not likely higher in 2022 than 2021

just out of curiosity how reliable is raw marks database?

yh I defs need to uncover the secrets!

screw maths hsc lol.... gonna make up for it in the sciences

lmao 4u 16b be like.

I would suggest looking on thsc, specifically in the internal tasks folder (not the trial papers), cos these have data analysis tasks. If I recall correclty the Hurlstone papers had a lot of data analysis!

that is true. But the level of complexity this test, was surely on par, if not even higher than the 2020 and 2021 papers. needless to say 4u was a huge leap. Just hope alignment is better!

you just assume the change of the common ion is negligible (i.e. it equals zero).... using this you can multiply the known concentration of the common ion, times that of the unknown variable equating it with the solubility constant...... then you can find the molar solubility of the substance!

Can I also have the answer to question 27 for the BOS Chemistry trial? Thanks! :)

- Its time for the sciences :cool:

Wait so scaling obs applies on the corresponding raw of your average HSC mark right?

ok cool. Got tired of filling out details tho. Praying they give more pages in the 3u paper lol

Are all the extra writing booklets for the hsc, the same for all subjects, since it asks us to write the examination subject on every one of them? I am trying to figure out if I wrote the question number I answered for English, cos i remember taking an extra booklet. If there was a box for the q...

This is a good idea!

oh yh fax. Then it would be 9! - ((8-1)! * 3!) - ((9-1)! * 2! *3C2) --> feel like I butchered this lol...

I tried using complementary. That is 9! - ((8-1)! *3!). I am not sure if this could be right. Can someone correct me if I am wrong? Thanks

idk but last year a 65 went to 88. And judging by the overall consensus that the test was as difficult if not more than last year, I would guess around 65, maybe 66 to be the cut off. But honestly, we do not have control over this, and this alone will make us stressed thinking about this. ig...
