Well, there's been no response so I'm gonna assume that the answer I gave was the one being asked for. So, next question:
Trisomy 21 is more commonly known as Down Syndrome. What are the common names of trisomies 13 and 18?

Correct. I was originally going to ask about Angelman and Prader-Willi syndromes, but somehow I doubt most people even realise that there are actually maternal and paternal genes, let alone that inactivating or losing the wrong one is so incredibly detrimental (that said, I doubt most people have even heard of Angelman and Prader-Willi).
For those wondering, Angelman and Prader-Willi syndromes are both caused by mutation in chromosome 15. The difference is that Angelman is caused by the loss (or non-expression) of maternal (female line) genes, whereas Pader-Willi is caused by the loss/non-expression of paternal (male line) genes. Interesting, no?
Anyway, Goto's question next.

Knowing Darkie she'll probably know it off the top of her head, hehe. 
We did briefly look at its formula in chem, but that doesn't mean I know it off by heart

You and your chemistry questions!

Erm...what? Never heard of anything like that. I'm going to assume that just means a list of elements that make up the human body. So, without knowing numbers and ignoring pollutants (ie heavy metals), I'll say...hydrogen, oxygen, carbon, nitrogen, phosphorus, calcium, magnesium, sodium, potassium, sulphur and iron. Oh! And chlorine too.
So that would be H?O?C?N?P?Ca?Mg?Na?K?S?Fe?Cl?, where ? is the number for the empirical formula. There would be a LOT of hydrogen, oxygen and carbon, then nitrogen as the next most abundant. Probably calcium and phosphorus would then be the only other ones worth mentioning, as the others wouldn't be all that abundant.

I will let you have it as you named the main constituents and I didn't really use the right wording. I should of asked for an empirical formula the answer is H15750 N310 O6500 C2250 Ca63 P48 K15 S15 Na10 Cl6 Mg3 Fe1
This then can be applied to a human body by its relative mass in comparison compared to the Mr/RMM of this formulae.

This differs from the composition by mass which would be inaccurate due to the differences between gender and just in general.

I see an accidental double-post. But honestly, where do you get these funky questions from? I've seriously never heard of anything like that, and it's certainly not something I would think a lot of people would know. Hell, even I had to take a guess at what the elements are! Then again, that may be because I always got the impression this is a 'no lookie up!' trivia. (no offense)
Okay, so, a question...
Taking a break from biology, this is more of a chem question. Ignoring the recently created 'superacids', what is the strongest acid known?
By 'strongest', I mean in terms of corrosiveness. Thus the answer is NOT sulphuric acid. Either a chemical formula or the name (or both) will do.

HF or Hydrofluoric acid.
Decalcifying and corrodes most elements except for chromium I think... just off top of my head.. melts glass as well so is used industrially to etch glass
Just had a lecture on acids and bases so kinda in my head
and if we were going by super acids SbF5 + SO3/HSO3F

Correct. As the 'etching glass' part tells us all, it's corrosive enough that it can't be stored in glass like most acids. It has to be stored in a special plastic.
Bring on the next question!
