I also just solved for mL o yuh yuh like 7.8 or smthn was the number and the magnitude was really small

i think if we all got 81L we surely did it right

yeah yeah smthn like dat I was just scared bc Ive never gotten such a high vol in a question but ig 125ml or however much ethanol is alot

also what HSC exam was similar difficulty to this one bc I feel like this one was easier than all of them, so I can reference scaling

also did anyone get like 50 or 70 or something Litres for the amount of CO2 produced for the ethanol question? (basically just x10^1 for magnitude)

yo did yall get A for 17

yeh i think lucid's working out for Q10 is wrong, bc u cant just say 2! for organising the teachers bc they are aligned in an isosceles triangle formation, and thus where you place the first teacher matters. What I did instead was chose a student (5C1) to place down as the student who was on...

wat u mean it was def 81 considering that

p = 2024 and q = 81

what do yall think a 64 out of 70 will scale/align to for this exam?

I got 10 as B, because I realised that since no more than 2 students can sit together, the general pattern must be the following, and then i worked from there (can someone verify dis)

for 16a), instead of using mok's method which seems like the right one, I assumed that the centres of the triangles was the origin, and just worked with c = (e^(i2π/3))b and a = (e^(-i2π/3))b. How many marks do u guys think i would lose given ii) is 2 marks and iii) is 3 marks? (from Mok's...

Just to confirm is this what u got

Course | Rank | School's Band 6s in 2022 Chemistry | 1/29 | 0 B6 Physics | 1/22 | 2 B6 (but apparently there were 3 on 89) MX1 | 2/15 | 11 B6 MX2 | 3/5 | 3 B6 English Standard | 7/115 | 0 B6 (school rank was around 100 last year)

(I just typed this up real quick so idk if i made a mistake or not I will relook through it now, hopefully this makes sense) So, when the magnitude of (p + q) is a minimum is when q is antiparallel to p (which just means that p is parallel to q but they point in opposing directions), as you...
