identify the ways by which physicists continue to develop their understanding of matter using accelerators as a probe to investigate the structure of matter Thanks in advance guys, I've only read stuff about how they are given kinetic energy and fired at target, is this meant to simulate...

I think you meant sodium Hydrogen carbonate HCO3- + H2O --> CO3 2- + H3O+ HCO3- + H2O --> H2CO3 + OH-

generally when we talk about chemical spills, we are talking about the container trucks, carrying the higher concentrations, because in school labs, they are diluted heaps. So if you have spilt a large amount of high concentration NaOH, you want to keep the heat liberated to a minimum...

Well you need to comment on how the anode would need to be inert, like graphite, platinum or titanium. Otherwise the cell will act like a galvanic cell, and the anode will react in the cell. Then put in equations and comment on the reduction potentials of the different substances - Chlorine...

thanks fellas, basically i just draw an angle to write angle, draw shapes to express trianlge or quadrilateral, and maybe i'll write equi or isos in a rush. --jetfan--

I wasn't sure if we needed to know how to measure smog but I read an article on how they measure ozone levels, they shine an ultraviolet torch thru a tube of the test air. The amount of light that passes thru is recorded, kind of like AAS. I'm not sure if this applies to sulfur/nitrogen tho...

yeah, thats what my process is, it is a model of a chemical equilibrium, should be fine

yeah, cazbah high, you?

*Describe, using equations, examples of chemical reactions which release sulfur dioxide and chemical reactions which release oxides of nitrogen. Just a simple roasting of Sulfur in air should suffice for this i think: S(s) + O2(g) --> SO2(g) - this is used in industrial plants and the...

Yeah, the transuranix elements are your best bet, talk about how they are formed through neutron bombardment etc. Also comment on how they are very unstable, do not exist for long periods of time, also the newer periodic table have named some of the unununium elements, and I think 108 has been...

just a question for people who have done/marked geometry questions, are you allowed to shorten your reasoning, i.e insted of base angles of isoceles(sp?) triangle, can you write base /_'s isos. /_\. If you know what I'm talknig about, feel free to comment

yeah ln is log to the base e, when you derive it you get1/x, you cant integrate it, but if you have an integral of f'(x)/f(x), the answer is ln[f(x)] + c. But if you're in yr11, you'll get to this next year.

well we performed a fairly good one. What you need is a 10mL and 2 mL pipette(i think thats the one, its the one with a tap you use in titration.) What you then do is get two measuring cylinders, fill one to 100mL, leave the other one empty. Then you turn the 10mL upside down, put it in the...

well these guys at our school(Cazbah) burnt a huge piece of the male anatomy into the grass at our bottom school, go check it out, tis quite funny

We did the heating of sodium hydrogen carbonate: 2NaHCO3 --> Na2CO3 + H2O + CO2 Because you are using a delivery tube, the top has a robber stopper, and because you are heating with gaseous products, there is an issue of pressure buildup and the top flying off, that is hy you need to heat...

Well I did both pracs so here it is: After the oil was initially added, you had two layers, the oil and the water, with the emulsifier mixed in, then after shaking for one minute, you still had two layers, possibly a third because some soapy froth may form, after 5 minutes, there is usually two...

Just a little thing too see how old everyone is doing their hsc this year, I'm 16, not turning 17 before hsc, true story

Dramatic features I've done Othello for module A and although we did not study dramatic qualities, my best guess would be more the acting and the type of dialogue. You would look at stage direction, character introductions and it can never hurt to discuss tehcniques; alliteration, repetition...

Im from cazbah(caringbah high) and damn proud of it
