re: HSC Chemistry Marathon Archive alright, next one Analytical data have shown that the pH of rain in developing countries is higher than the measurements obtained from industrialized areas such as Central Europe. Suggest the causes of this difference and explain its impact on the marine...

re: HSC Chemistry Marathon Archive yeah, the thing i didn't get was how the hell was i meant to address the justification bit on how esters are produced am i supposed to talk about efficiency or some crap lol

re: HSC Chemistry Marathon Archive oh fuck when i look at my response, mine looks like a piece of shit :(

re: HSC Chemistry Marathon Archive shiet, dis Q looks tricky but i'll try to answer it nonetheless - these are from my notes btw (so it might be a bit convoluted lol) --- Argument We conduct the procedure of preparing an ester because it allows us to identify if there any manifestation of...

oh derp, i did not see that thankies ^__^

re: HSC Chemistry Marathon Archive all g brah tbh, it's those minute things in short answers that can ring alarm bells in markers and thus you'd get marked down for using incorrect terminology (as you would know - chem marking is anal af)

re: HSC Chemistry Marathon Archive Solid response, except I'm not 100% sure about this bit. I thought that it has to be moderate temperature when monitored to ensure that (like you said in your answer) an appropriate compromise is maintained between maximum rate (achieved at higher...

i think that was implicitly highlighted in my guide lol :p

Too many variables tbh - depends on your overall marks. But generally, you want to do well in English because a mark in the 50-70 will probably drag you down. You might scrap a low 90 ATAR, but it's somewhat unlikely with English marks like you mentioned lol. If you were in the mid b5 however...

re: HSC Chemistry Marathon Archive gg no re

wait till you guys start permutations and combinations :haha: that shit was hard for me back then lol

w0t, sif u didn't realise. m8, lrn2read (i kid, i kid :p) o i c haha - dw, you'll be fine lol. i'm currently afflicted w/ a cold atm which sucks :( so i haven't been productive lately as i would've liked

hello pornsky (huehue)

if you feel it's necessary to reiterate your thesis when answering said exam question, then yes, you can do it

is there anything we can help you with?

re: HSC Chemistry Marathon Archive nope, all you have to know is that there's thermal and catalytic cracking - they don't even ask why it works lol - it's pretty bad aha

re: HSC Chemistry Marathon Archive pls yes, that's right. if you have a container of apples where the volume has decreased, then the pressure would increase as the apples would struggle to find room to move around more if the area was constricted. so in this case, we want to decrease the...

re: HSC Chemistry Marathon Archive oh, does it? so it comes back to the inverse relationship of volume and pressure yes? but is thunderstorm's answer correct? (cos it does sound right)

you need to clear your system of such dirty filth lol
