what is sulphurous acid???? cos i've never heard of anything like that in my life, if it's in the exam i'll have no idea what to do, isn't it just sulphuric acid?

i think it was just a typo two amino acids are dipeptide and three are tripeptide, (lol something i actually know haha) and im far from a chem freak lol, i struggle to understand simple stuff as you could see by my stupid question only 3 more days an it'll all be done ahhhhhhhhhhhhh the...

hmmmmmmmm no i have not been living under a rock i'd rather study than obsess over my marks, after all whats the point in worrying about your mark cos your only gonna get it if you put in the study, people seem to be far more preoccupied with the marks and stuff rather than the exams i...

lol yeah i dont worry about the marks that much but i kept seeing people talk about "raw marks" and so i started to wonder maybe it was important or something, i figure you go in do what you can and thats it, its done, for good.

ok thanks, all this marking stuff is sooooooooooo confusing

awwwwwwwwwwww thats so crappy, it wouldn't take my mark down though would it? if i got lower than an assessment?

ohhhhhhhhhh ok so like if you get a 70 in the exam (which is what im hoping for,thats a good mark for me), but i get like 97% for assessments does mean it would bring my hsc mark and therefore my uai up? cos that'd be so cool,

what the hell is a raw mark????

oh ok then thats simple i know that stuff, i hate it when they word q's funny and make them hard to understand. thanks though

i've done it before for the ethanol as a fuel stuff and it was fine, saves writing blah blah does this but 2nd blah blah does that, its not breaking any rules or anything and you would know if it wasn't allowed so i'd do it.

lol yeah, sorry people

yes but if their like me and completely have no idea whats going, theres no way i would have been able to understand stuff if id used my own ifo, its just too hard.

in google type hsc online chemistry go in the first link and it should have all the chem stuff, it has this years so im guessing it'd have last years as well

ok thanks sorry i was gonna write forensic on it but i figured id be more likely to get an answer in the main forum.

lol thank god for that then i was wondering why i had no idea of how to do that, thanks for your help

identify data, choose equipment, plan, and perform a first-hand investigation using flame tests and/or spectroscope analysis as appropriate to identify and gather first-hand information to describe the emission spectrum of a range of elements including Na and Hg does anyone have an outline...

ok and do you know what the answer to this is, cos i have absolutely no idea, im so screwed for the option part of this exam. identify the functional group in glycerol? AND compare the reactions of both glycerol and 1-propanol when they react with cold dilute KMnO4? thanks for the help

how do you determine amino acids and peptides from proteins????

okies thank you

does anyone know if we will be asked to draw diagrams of stuff like glucose, fructose, sucrose and maltose (forensic chemistry) and others like cellulose and starch????
