Jeez... looks like I'm a lucky boy when it comes to school networks... I_F

What mass of ZnSO4 do you need to make 200ml of 1M solution? ////same with CuSO4 Calculate the mass of 1 mole of both solutions. A 1M solution is 1 mole of solute dissolved in one litre of solvent, off the top of my head, so then you divide the mass by 5 to get 200 mL. Also, with...

No, you have not stuffed your chances. This is only one assessment task. Compare your mark to others in the class. They may have done equally badly. If not, then you need to put in extra work for the rest of your assessment tasks to bring up your class rank. How much of your final mark was this...

Yes, because history has taught us how we have evolved to what we are today. I'm impressed. Four millennia of nearly unstopped conflict, war, famine, and fight for survival. And trust me, without maths, I think life would be a lot worse. A lot of people don't realise how important maths...

Care to justify that? :) I_F

And say "you need to know about out past, to understand and appreciate the present and the future" Sadly, looking back on human history, the only thing we learn from history is that we don't learn from history. Maths.. is just numbers and squiggles that give people headaches. I'm not...

nVidia has been ahead for a while in the mid-range market thanks to the 6600GT, but it took over the top end with the June release of the 7800GTX. Currently, it has the best performing GPUs across the the board, and we're waiting to see what ATi's next-gen card can do. I_F

Our school's network security is non-existant once you're registered for use. IM clients, P2P, I don't think any sites are blocked, and we can download what we like. The wireless has WEP encryption and MAC address filtering, so you can't get in without being authenticated, but once you are, run...

If a number is divisble by 4, and then that factor is divisible by 2, then that number is divisible by 8. E.g. 4 goes into 32 eight times. 8 is divisible by 2, so 32 is divisible by 8. 4 goes into 20 five times, but 5 is not divisible by 2, so 20 iss not divisible by 8. I_F

I was doing some integration today, and I kept leaving it out! So friggin' annoying! Automatic one mark off! :p I_F

drewgcn, that logic works for me. Kudos! :) I_F

The only other equations that you might need are glucose from CO2 and H2O (which I think is 6CO2 (g) + 6H2O (l) -> C6H12O6 (s) + 6O2 (g), not sure here), and the burning of ethanol (C2H5OH (l) + 3O2 (g) -> 2CO2 (g) + 3H2O (l)), which produces CO2 and H2O which can then make more glucose, to make...

We've only gotten one task back so far. We've got two pending, and three more to go. I_F

Whenever a question asks "by considering the sign of f'x and f''x...", you must find the first and second derivatives of the function. You cannot substitute in points as that is not what the question is asking. The first derivative tells you the sign of the gradient and any stationary points...

If you despise it, there's no reason keeping it. Good on you. :) I_F

You won't need an equation. The only one you might need is the one you already have - ethanol from glucose. From my understanding, this is all you need on that point: 6. Dehydration: The alcohol will then pass through a dehydration system where the remaining water will be removed. You...

You won't need an equation for it. It's basically like evaporating an aqueous copper sulfate solution to get copper sulfate crystals - no chemical change involved. Just mention it as a part of the process. :) I_F

I'm planning to: * Enjoy my P-Plate freedom (w00t got them on Wednesday) * Finish off the 2U Maths course * Write out a paragraph for each dot point in the first Core Modules of Physics and Chemistry * Relax and spread the work out over six weeks I_F

From assumption = (8-2k) + 6k+8 Shouldn't this step be (8N-2k) + 6k + 8, since N isn't necessarily 1? Since 4 is a factor of 8, it is divisble by multiple of 8s. If M = 1, 3, 5, 7, 9, etc. then 4M is not divisible by 8. I'm not sure whether you're right here or not - if you work it...
