Advantages Easy, Medium or Hard?
Disadvantages Some are IMPOSSIBLE!
I have made up some science and maths brain teasers and put them into four catagories. If you know the answer to one of them then put it in my PRIVATE guestbook along with the subject, difficulty and question number. When someone gets the correct answer I will put the answer on here and I'll give the person a little mention, plus, I'll put another puzzle into one of the other sections. there will only be a maximum of ten puzzles at any given time.BIOLOGY
1. (EASY) Can you work out the names/chemical symbols for all five of these? The first one is done for you. You may need the periodic table for this one!
Zn = Zinc
Au = (a)
(b) = Iron
(c) = Oxygen
H = (d)
(e) = Helium
3. (HARD) Number 1 and number 2 were the easy ones. Lets see if you can crack the next two! For NaOCl you have to find out it's real chemical name (c) and it's common name (d). CLUE: It has already been used in 1 or 2.
H2O (water) = 2 atoms of H (hydrogen) + O (oxygen)
(a) = C (carbon) + (b) atoms of O (oxygen)
NaOCl (c (d)) = Na (e) + O (oxygen) + Cl (f)
Well done, you have finished the CHEMISTRY section. A new puzzle will be added every time an old one is completed. It may be added to any section (biology, chemistry, physics or maths.)PHYSICS
1. (MEDIUM) In this puzzle you'll see there are six different questions. Each question comprises of only a number. The challenge is to find the square root of that number. The first one is done for you.
(a) 144 (square root = 12)
