For question 20, why is it D (which was a value) considering that was a static equilibrium? like doesn’t N2 + 2O2 -> 2NO2 So NO2 isn’t going to decompose?

The uploaded paper doesn’t have the questions so I can’t check working out. I think ppl are saying 18-A, 19-A and 20-D tho

How did you guys prove NH4Cl was a B-L acid? I’m trying to write up dot point solutions

Okay so so far these answers should be correct for 1-16

Lol I had a typo for question 1. Please don’t pour organic stuff down the sink :D Hmm you guys are probably right about 9 since it gets neutralised really fast.

Rather than wait for some genius person who got everything right, how bout we just compile everyone’s answers. Here’s what I had for everything 1. D 2. C 3. B 4. D 5. D 6. C 7. A 8. B 9. C 10. A 11. C 12. B 13. A 14. D 15. B 16. B 17. A the full paper isn’t uploaded yet so I can’t check this but...

Yay thanks. Also carrots I'm gonna miss seeing u you're like everywhere :) Was chem your last exam?

Can someone confirm what they got for Compound C? It was hexan-3-one right??!

I got hexan-3-one cause it matches with the H NMR data

Ooh okay thanks carrots. Okay that alignment makes me feel super confident now :)

Genuinely confused bc if you look at this photo I’m assuming these raw marks are marks out of 70 transformed to being out of 100 but none of them are actual whole numbers. Like for 2020, 72.9/100 = 51.03/70. So are these the marks people actually got in exams? Also no way it’s that low to get...

Ohh this makes so much sense. I get what I was doing wrong now lol I knew smth was off.

Follow up question, why does it not work for when I'm going from y acceleration to y velocity? Like if I do this then i end up with an extra 10.

Sorry if this is dumb I literally haven’t been taught anything for mechanics. But regarding projectile motion can you use a definite integral when going form acceleration to velocity etc? Instead of letting t=0 and subbing in. like this…

Okay so long and repetitive way it is I guess 😂 Good to know my brother was wrong about something for once

Okay so ik I’m embarrassingly late in doing content but Im so lost on mechanics rn cause our teacher left and now we have this old lady who can’t teach for her life. So…how exactly do you lay out projectile motion question. I have 3 options right now. 1. What we learnt in extension 1, which was...

Hiii, thanks for responding why is this more feedback than that I've gotten from my teache rin the past year combined I'm a bit lost as to how to answer the "to what extent" part of the question (I feel like I just skipped it cause I don't know how to answer it) could you please give an...

it seems like the whole world has done their trials already, yet I haven't even started. Hi, could someone please give me some specific feedback on this. I struggle a lot with English and its really hard to write better essays when the only feedback i get from my teacher is "Deeper analysis...

Wow these are some speedy replies :) Thank you both so much! Just to clarify, by lower entry guarantee I mean that I’ve been told (by family friends and a random substitute teacher) that “universities will accept me no matter what bc I’m an international student and they want my money”. I see...

Hi, just wanted to see where I’m heading with my current results. My goal is 92 which guarantees an entry into a bachelor of commerce at Unimelb, but I’m not sure if I’m gonna get there with my current marks. I go to a kinda bad school, our rank is usually around 200 but last year was 170 and...
