  1. oh that is good, hopefully i helped, actually it helped me lol. if anyone else has chem questions, feel free!

     

    oh yeah, i have no idea about why they bond covalently and stuff. guh!

     

    but i just did really well on a test about photochemical smog, water treatment and silicates :) besides that i was either failing or only just scraping a pass, it made a nice change

  2. There is a little bit in the column of my text book:

     

    significant figures

    This is to remind you to give your answers to all calculations to a degree of accuracy which is consistent with your apparatus and data given. If you have to determine how much solution to run out from a burette the answer can only be to the accuracy of the burette. Your calculator may read 22.7134 mL, after doing the calculations, but your answer has to be to 22.7 (3 sig figs).

     

    Just some random stuff i can remember about them:

    -Increase in amount of numbers, eg 4 sig figs /3 sig figs increases the level of accuracy, so 10.9 (3 s.f.) is more accurate than 11 (2 s.f.)

     

    -From personal experiece; DONT ROUND TOO EARLY, i have lost marks from doing that, and you can only give ure answer witht the same amount of sig figs that the data given/collected has.

     

    -In numbers less than zero the zeroes after the decimal point are not significant, if in doubt convert to scientific form (0.00217 = 2.17 X 10^-3)

     

     

    I hope that has helped, Good luck for your test!

  3. hehe, wouldnt wear them in the water though...

     

    i went to wholers to buy a present for a friend the other day, and they had lollipops there (bit random yeah) and they had stickers on them saying 'lick my lollipop' it reminded me of lollipop and i took a picture of it, but my motorolla wont connect to the computer lately so i cant upload them :(

  4. lol, wearing three watches would annoy me it one was slightly out from the other, i would have to have them exactly the same.

     

    ...i just noticed he looks quite buff in that pic.

     

    yeah, all u need is simple maths to read a binay watch it would save the hassle of reading numbers, there are some pretty cool ones at thinkgeek.com but i doubt this one would be there

  5. Once upon a time, in a land called Seattle Washington, there lived a grumpy old troll under a bridge. He spent most of his time crushing Volkswagen Bugs, and frightening the neighborhood children. Once I told him about the wonders of the Mika Fan Club, he decided to join!
