when i enter username and password I can't log in to SAM same page keeps appearing? Anyone help.:confused:

chemof art part 4 2nd dotpoint right column -perform a first hand investigation to observe the colour changes to a named transition element as it changes in oxidation state dot point 4 is about oxidising of KMno4 Are they different pracs. I did this topic on my own

does anyone know the experiment on -observing colur changes of a named transition element How was this prac done? Any help would be great!!!

has anyone got the independant trial 2003 answers????:confused: :confused: :confused: it would be a good help if someone did.:D :D :D especially for the option topics, in particular chemistry of art. thanx.:cool: :eek: :cool:

if youve got the success one book its in there.

sorry that 2+ is a typo it is suposed to be 3+

dis wat i got on it... the max oxidation state equals the total number of 4s and 3d electrons in the atom. The higer oxidation states tend to be when a transition metal is bonderd to a more electronegative atom such as oxygen or with the additional loss of 3d electrons forming simple...

he cause i did chem of art by myself and the rest of my class did that shity shipwrecks, i didnt get a chance to do any pracs but i found stuff on the KMnO4 prac and the flame test are simple.... so anyway heres the dot point - perform a first hand investigation to observe the colour changes...

ah i have a feeling it could be the prac on observing the known transition element as it changes oxidation state

D has to be correct, the clock was 10hours on the spacecraft. How many question are there about the people on the spacecraft being younger than the people on earth after they returned.

i agree it was there last year so it prob wont be there again... but it was in my trial so im cool with it.

theres a good comparison in the maquarie revision book.

the test was pretty good, i was happy cause all the stuff that i didnt want to be in it wasnt. hopefully i got bout 75% that'll do fo 1 night study.

smart arse i used 1/2 x base x height using base as acosx / 1 + sinx and height as bcosx / 1 - sinx

did ne one else prove q4 (b) [111] to be ab/2 instead of ab?
