ok- the first one I believe is Calcium, the second is a little hard , I think the substance you called Mn04- should actually be Potassium Permanganate, if so then the cation in the second solution is Iron 2+, the third is definitely Iron 3+. I may be wrong so please feel free to correct me if I...

That's what we were told.

That is so harsh!! I can undertsand the teacher taking of a mark for not finishing the table, but 2 marks is just stupid!! You had all the right info in there which should guarantee you at least 2 marks. Did you see the Head of Science at your school maybe they could sort it out?

Same, I got 83% and my usual mark is around 93% but I'm coming 2nd out of 15 so that's good.

73% came 6th, average was around 48%

No you are totally correct. This topic is somewhere else too and that is the answer all 3 of us who attempted it got, including CM-Tutor.

Cool, I did get it right. Thanks guys!!

What answer did you get Xayma? So I can check it with mine, I think I'm wrong.

Yeah, I am refering to CM_Tutor, amazing knwledge of the subject.

It's a shame there isn't a Biology Tutor on this site, like there is for Chemitry, who could answer this question online for us.

Hmm, that is really weird.I haven't come across that before. But logically speaking, it should be the same size as a white blood cell.

Thanks, that helps a lot guys!

Our school enters every year, this will be my second year doing it. I think ours is during a school day at Sydney Uni or UNSW. We did okay last year, our total error was way off because our third member got 50 000 and the other two of us got 4 and 50, but its all good, it's a great experience so...

Thanks, I was having a bit of a headache myself trying to see if I could draw the structural formula because I wasn't really sure but that clears it right up for me!!!!!

I am thinking of going into teaching. I am a bit worried about it being non specific though, I am not sure whether or not to take now. I really would like to specialise in Chemistry.
