My watch is a chronograph so i couldve used it as a stopwatch. Im sure it's fine, the supervisors just stopped and looked at my watch for a like a few seconds, no hassles
Guys overall thoughts on Industrial Chemistry
For the choosing for electrolytic i picked the first one, which had products Cl and O gas. I think that was 'X' and it's wrong apparently because industrial is concentrated brine :(
Apparently it's the second one, Y?
15 was easy!
n = V/Mv
Change 'n' to mass/molar mass
Make 'V' the subject.
your mass is constant (1gram) and your molar volume is constant.
Hence you have v = Mv/mm
The smaller the molecular mass the greater the volume. Calculate all molar masses of the answers, and 'D' was the...
This 4U is so messed up. I remember when i was doing it if you get around 67+ raw mark, it gets heaps boosted. But like to 91 ? Then what's the difference between raw 90 and 95 o_o
AGREED - Hardest questions was the drug or money one. Two different patterns which has actually different, actually screwed me over :(
WAIT, what triangles question?
Already knew i screwed up the LOAN REPAYMENT question :( Lost a mark on MCQ, a mark on that limiting sum to with the DRUG question which i couldn't comprehend, mark on the derivative curve and mark off for finding point 'P'
Hopefully ~93 raw
I no clues about estimations, but I reckon 45
Apparently low 70s and lower aren't any better than there raw marks. That's what i've read, iDK. plz correct me if i'm wrong
You're gone mate. I don't think it's a MAJOR problem, because they are handed in with other stuff, and for ENGLISH like today, there's this sheet that has your number on it.
