yeh apparently they are borderline as well =P

lol well i'm sure our parents will be happy when they see the final results. Besides it's probably them trying to motivate us to do better (I hope lol) which fails.

lol I came home from school where I received an maths 4u result, got 94. This is how my conversation with my mum went; Me: guess what mum Mum: what? what??? Me: I got my 4 unit result back *smile* I got 94 from 100 Mum: 94 !!!! where did the other 6 go?? lol it burns

Natural rubber (poly-cis-isoprene) comes form latex of the rubber three, this latex consists of a polymer formed from the monomer called isoprene {IUPAC name for isoprene is 2-metyl-1,3-butadiene}. The precipitation of the rubber parrticles from the latex produces an elastic and sticky...

the molar ratios are; NO : O2 : NO2 = 2 : 1 : 2 moles initially = 0.25 : 0.12 : 0 moles moles used/formed = 0.20 : 0.10 : 0.20 moles at equilibrium = 0.05 : 0.02 : 0.20 moles therefore since the volume of the vessel is 1L, the concentrations are; [NO]=0.05 M, [O2]=0.02...

The balloon devices used to measure ozone do so in a very similar way to the satellites. The balloon achieves this high height as they fill it with helium which is the lightest gas (hydrogen is lighter but it diatomic while helium is a noble gas). These devices measure the amount of ozone in the...

lol I don't have any questions now so what do you want me to ask, and to answer your question. The dry cell also had a very large affect on society as it was one of the first portable batteries to be produced which allowed it to make torches, radios, toys and clocks to be portable. However, the...

AAS is extremely sensitive and can detect concentrations of elements at the parts per millions and even parts per billion concentrations. This process works by spraying a sample mixture into the flame which vaporises the atoms while a specific beam of light is used to determine the concentration...

A buffer solution has comparable amounts of a weak acid and its conjugate base, this will form an equilibrium at a certain pH and will thus resist be able to maintain an approximately constant pH, even by the addition of significant amounts of strong acids or strong bases. actually the buffer in...

lol yeh but then again you could just go through the more detailed and important things. Some stuff from the core modules which I reckon need to be looked at closely are production of ethanol and its uses, an example of a biopolymer (PS I got an assignment with a lot of information on a...

not sure if you have heard of these sites but they have an abundance of chem papers but not sure if the option forensics is there, they are peer doc .net and hscguide .net. by the way people, the examiners are looking for new questions because they don't want to repeat questions over and over...

on the information sheet given in the exam the volume of gas at room temperature (25*C) and also at 0*C are given, and also the heat capacity of water, ie 4.18. Although it is important you know how to use them. Something in acidic environment that I would recommend you learn is approximately...

yes although citric acid does not ionise completely; ie 100%, whilst sulfuric acid completely ionises (just for your information, in the core sulfuric acid is known to ionise 100%, however only the first ionisation goes to completion and the second ionisation [HSO_{4}^{+}]), this is a...

the equation for the Haber process is N_{(g)}+3H_{(g)}-->NH_{3_{(g)}}. When the system is moved to container of lower volume the pressure will increase, according to Le Chatelier's principle the equilibrium will try to oppose the change in pressure, therefore the equilibrium will move to the...
