There is no way that Chemistry is the second highest scaler after Maths Extension 2. I_F

Why should it be HSO4? If the reaction doesn't balance, odds on it probably doesn't happen. I_F

Not going to happen. Well, not anytime soon, judging by the (lack of) progress of the Doha Round. By the way, we aren't doing too bad with manufacturing - exports of manufactures currently comprises about 20% of total exports, and that percentage has risen over the past decade or so. This is...

I'll warn you now: Speaker for the Dead, Xenocide, and Children of the Mind all get very, very philosophical. The latter two are especially so and also quite long. If you're not fond of that type of novel, check out the "Bean Quartet" - an offshoot from Ender's Game that follows Bean. The first...

The sodium hydroxide dissolves in water to form Na+ and OH- ions. When solid sodium is reacted with water, you get sodium hydroxide and hydrogen gas. I_F

I'm pretty sure H2SO4 reacts with NaOH to give Na2SO4 (sodium sulfate) and water at a ratio of one mole of sulfuric acid to two moles sodium hydroxide. I don't think they react to give a hydrogen sulfate. I would guess that in your prac you had insufficient NaOH to react with the H2SO4. Hence...

Our captain is academically lazy. He's just dropped from 2U Maths to General, and never really works that hard at school. He was just the most popular with the students and the teachers. I_F

Why then are all the countries at the bottom of the world before the globalisation era still at the bottom of the world now, whilst all the developed countries have stayed on top and even stretched their lead on the rest of the world? Globalisation has benefited advanced economices and newly...

Picture books are excellent texts to use. Make sure you talk about the visuals and how they interact with the story - you will only be marked down if your analysis is too basic and childish. I_F

Find dy/dx, and then find the values for which dy/dx is positive. I'll get you started: dy/dx = 3x2+ 24x + 45 Now find where the parabola is [i]above the x-axis[i]. That is the domain over which y is increasing. I_F

Globalisation has also resulted in a lot of bad stuff, such as the creation of a financial market system that can destablise a country in mere hours thanks to momentum trading, global organisations which can be kicked around by the world's most powerful economies, and countries which are so...

I don't mind graphs, because in the exam it's almost always gift marks. "Here is a function. Draw the log of the function, 1 over the square root of the function, and the absolute value of the function".:D But complex numbers and conics... they're much more painful. :( I_F

Extremely hard to tell from that information. Trial exam marks and overall ranks would be needed to get an estimate that's even in the ballpark. From that I could probably predict anything from about 70 to 90. I_F

Conics looks much more evil than integration, and integration is much less annoying than complex numbers. Integration is really just playing around with algebra or trig to get things into a integrable shape. Once you've done a few, it gets much, much easier. I_F

No. No Preliminary marks carry over to HSC. I_F

Your rank affects your UAI much more so than the marks you get in assessment tasks. Because schools set tasks of varying difficultly, the only fair way of judging things is through relative ranks. You can get high marks in assessment tasks, but if everyone does too and your rank is low, you'll...

The marks for school assessments don't matter as much as the ranks you achieve. Some schools set really hard assessment tasks, and others relatively easy ones. It's the ranks that are used to decide your moderated assessment mark. Keep your rank high, get all band sixes in the HSC exams, and you...

Our school doesn't have prefects, and if we did, they'd probably be more likely to play cricket or stick their hands up cows than organise afternoon tea get togethers... I_F

This is where I think it falls down. Magnetism is a relative effect - the electrons must be moving relative to their immediate surrounds to generate the electric current. If the train is moving at a very fast constant velocity and the electrons are stationary inside the train with an observer...

If the derivative of ex is ex, then it follows that its integral is also ex. This, along with the chain rule is all you probably need to know to integrate exponential functions: ∫e2x+1dx If we finish with e2x+x, we must have started with e2x+1, since the derivative of ex is ex...
