2010 Chem midyear - what did you think?

[chansthename]

Way too easy. My silly mistakes will make me get an high A now... they should've made it a hard exam.

I walked out disheartened about the fact that mistakes are going to hurt real bad

[scatteam_2]

r u kidding?
i made so many mistakes its not even funny
i had no idea how to do biodiesel question
f**ked up big time

[kyzoo]

Mmm 3(mass of chlorine in insectiside sample), 5(total volume of gas produced), 15 (insulin), and 18(oxalic acid) were the only really tricky multiple choices ones

freaking got 5 wrong cause I'm a retard and 4 cause I couldn't be stuffed thinking too hard.

but yea lol MC was quite straight forward.

ey Kyzoo what you do for the concordant titres?

[azn_dj]

Im really surprised that in the multi choice, they called it an amino
ESPECIALLY since they kicked a stink last year about it being an AMINE.
Make up your F****ING minds, VCAA!

ey Kyzoo what you do for the concordant titres?

Mm I was taught that concordant titres are meant to be 0.1mL within each other, so that each titre taken into account is no more than a drop (0.05mL) away from the true titre required.

[Blakhitman]

So you used 21.97, 21.99 and 22.03.

hmm ok well at least I got 3.82% xD

[Akirus]

I used 3 not because of +/-0.05mL, but because I recall that you're meant to use 3 concordant titres.

[Blakhitman]

lol I was going to, but then I saw that they weren't "concordant (according to my definition)" so I didn't.

same with me. I though 3 concordant titres so took the three closest to each other titires for my average.

[rasangi]

i think A+ will be 90% +
A will be .. 80-90%
B+ 75-80
B 70-80

C+ ( average) about 65%

A+ is never above 90% no matter how easy the exam is, for science subjects anyway.
