Newbie, what degree(s) did you do in uni? Sorry if you answered this already, but I can't find it.

Thanks! I made a stupid mistake, I forgot to convert the 20.21Kj back into joules I just left it as kj and I was like wtf. Thanks again for solving :)

A student did an experiment to determine the molar heat of combustion of 1-propanol. The following results were obtained Mass of 1-propanol burnt - 0.60g Mass of water heated = 200g Initial Temp of water = 21.0C The molar heat of combustion of 1-propanol is 2021kJ mol-1. Assuming no heat...

Find motivation to do well.

Re: heat of combustion question. Molar heat of combustion increase with chain length because the longer then chain the more energy you need to put in to break these bonds to combust and therefore will result in a larger molar heat of combustion.

well assuming that its the one nightweaver666 wrote that you said it was, dy/dx of x^2/6 will be 2x/6 which will simplify to x/3 and then dy/dx of -x is just -1

x/3 - 1

As if you could not read this novel by Saturday. It's a good book, why not read it you could easily do it in a day.

Probably just going to study math and phys, and probably English.

There's Sum, divisibilty, inequalities, you can get logs, factorials and ones that include sigma not sure if there are anything else, but you can't really be chucked a question e.g say induction with logs if you haven't actually learned it at school/

Here's the old chessboard problem, dunno if anyone's posted it yet. The man who invented the chessboard goes to the king and delivers it and says, I would like 1 grain of rice for each tile but doubling each time, (8x8 Chessboard) so he starts with 1 grain of rice fro the first, 2 for the...

hahahhahahah yes!

hahahah

I swear some school did this LOL

I'd say Chem & Phys since you're doing one history already, I really like Phys and Chem and I glad a picked them. It really depends what you want to do in university, if you're doing a science thing eg eng/med etc I say its best to pick Chem & Phys. Geology I wouldn't pick if I were you, I...

Bump for Drong, he's great with maths, and the price is great!

School doesn't matter sorry for the late reply I went to sleep really early yesterday because I was tired, Thanks Spiral :D just send me a whole bunch of what you got :D

Hey Spiral, sorry to bother you and everything but do you reckon you could send me Prelimary 2U Pastpapers please since I can't find as many oppose to 3u thanks :)

Take MX1 it's worth it. You'll probably end up dropping another subject over it.

Revise everything I learned this year, I screwed around too much, need to ace my yearlies especially for maths haha need to secure dat 4unit spot. :D not much holiday h/w but I got physics assessment which I should prepare.
