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

yep it was

 

[Jane Mao]

yep it was

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

How much of graphs are you supposed to write in pencil?

I wrote my entire graphs, including numbers, title and the thing on teh side in pencil. Is this okay?

 

[Masaken]

in my chem class no one does physics and most of us do chem+bio

bio is shockingly small in my cohort (most of my grade do chem + phys or bio), around <50 (tbf they all dropped in year 11 cos the prelim course sucked) while phys is a little under 100 I think. chem is a little under 150 I forgot the exact number though

in my school people were crying to get into bio BUT I WAS CRYING COZ I WAS DOING BIO

yo did yall get A for 17

 

[blob063540]

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)

 

[blob063540]

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

I don't even remember but I used pV=nRT, I think I got 80 something L but I forgot completely and could be remembering entirely wrong

 

[natsnapshoot]

I don't even remember but I used pV=nRT, I think I got 80 something L but I forgot completely and could be remembering entirely wrong

Yeah i also used pV=nRT and got 81.something but I was second guessing myself tbh

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

 

[hb0623]

Yeah i also used pV=nRT and got 81.something but I was second guessing myself tbh

yeah same I got 81.7 but was very skeptical because it seemed way too high

 

[blob063540]

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

Alignment is probably gonna be very similar to last year

 

[Interdice]

I was goign to use that, but isn't that formula only in the year 11 course? In teh gas laws part? because there is no mention of it in the HSC

I only used it because it was the only way I could see to get volume from the information provided so I was quite unsure- definitely thought it was only a year 11 thing

 

[Masaken]

i got 81.7L, thought it was about right because i remember it was like 3.16 moles and 3 moles of gas is heaps of volume. 1 mole of gas is 24.79L at slc for example

ok good I got 81 makes sense we allg allg winning fr

What did everyone get for the Mg2+ ion concentration question?

 

[hb0623]

What did everyone get for the Mg2+ ion concentration question?

Something to the power of -10 or -11 that one I'm also pretty unsure of

 

[Goldattacker40000]

Yeah I got something to the -11 but it looked really small in comparison to the other given values so don't know if i did it right
