idk if this would suffice but -AAS was developed by Alan Walsh to detect concentration of metallic elements in ppm and ppb range -Function on fact that each metallic element absorbs a specific wavelength of visible light -Test solution is fed into nebuliser and is atomised in flame -Hollow...

i know that feel man... During my english exams, ihad a very, very bad flu, headaches, bodyaches, runny/block nose and to make things worse, i had to cram 3 days before the exam lol I did not get a dr certificate, but i slept a lot, cram 4 hr or until i feel tired, then take a nap rinse and repeat

I doubt you'd have to draw a corossion/time graph (i dont think it even exists O_O, dont take my word though lol) Time is not always independent If you measuring how long it takes to rust to a specific amount, time = dependent If you measuring how much rust forms for a given time, time = control...

help with what , ask me some questions :) FIRE AWAY

Idenpdent variable is what you are changing Dependent is what you are measuring as a result of changing So Independet would be different metal, iron and stainlesssteel

just keep the examples, i doubt you'd be picked out for plagerising, unless you copy someone sitting besides you word for word I reckon its fine, just like in maths, you copy their EDIT: (TTEXBOOK) proof line for line yet that is not plagerising same with science me thinks O_O

bumpity bump, does anyone understand what I'm asking? Do we use Ca2+ equivalent or do we also take into account the Mg2+ when measuring hardness of water in ppm

Since hardness of water is the amount of Ca2+ and Mg2+ in it, when finding the hardness of it in ppm, do you add the amount of both Ca2+ and Mg2+ in ppm or do you only use the Ca2+?

yes, know it, there's no harm in memorising a little extra information

holy shit, 3 aus soldiers being gunned down while at least 13 usa soldiers killed in suicide bomb, rest in peace :(

holy fk you guys all seem so prepared ? MAkes me feel bad now :(

haha, reading over my notes i picked out so many things that were wrong lol

I read that Shallow water has lower dissolved oxygen than deep ocean water Is that wrong? I reckon it should be that Shallow water has more dissolved oxygen then deep ocean water due to wave action etc... but since shallow water is generally warmer it means solubility of oxygen is lower than...

i had a hardcore flu during first 2 weeks of exams, coughing, running nose, body aches, headaches but now its all healed :) I suggest you get at least 8hrs of sleep, drink OJ, no fried food ofc, eat healthy (like soup and stuff - if you cant handle the blandness of it, eat it anyways), drink...

For the past week, I have barely been studying for my exams but it all changed today :speechless: Holy fuark, I suddenly started feeling an urge to study for my last two exams Chem/Phys today and have been doing so since 4pm. I re-read my chem dot points 3 times, highlighting, and absorbing...

prediction is that im pretty sure there is going to be a question on Particle accelerators involving drawing a diagram for Q2Q

harderr :(
