    Hey guys, use this thread to discuss any questions you may have and I'll try my best to answer them, I'll post question sets for us all to do, and others can post theres too. Here's a set of questions, give 'em a shot and I'll correct you if wrong.


    1) What would the atomic structure of an element with 16 electrons be, (e.g. 2,8,2)

    2) What do we call the compounds that contain only carbon and hydrogen atoms?

    3)
    The most viscous hydrocarbons are likely to leave the fractionating column at the top, bottom or middle of the column?

    4) What is the general formula for an alkene and an alkane?

    5) What is the structure of the earth, from the center to the surface?

    6) What is the most abundant gas in todays atmosphere, and what was the most abundant gas 4 billion years ago

    7) Which chemical is needed to harden vegetable oils?

    1) Sulfur
    2) Hydrocarbons
    3) Bottom
    4) Alkane = 2n + 2, Alkene = 2n
    5) Solid inner core made of molten nickel, outer core, mantle and crust (varies from 5-70 km thick)
    6) Now = nitrogen (78%), 4 billion years ago = hydrogen / helium ??? (sorry my memory's toast i've had a couple of beers)
    7) Nickel catalyst???????


    But the real question: WHO HAS JANUARY 2014 H CHEMISTRY?
    1) Correct - although I meant to lay it out in the form of 2,8,6
    2) Yes
    3) Yes
    4) Alkane = CnH2n+2 Alkene = CnH2n
    ^ You did it correct but in the exam I'm certain you'd need to put them instead of just 2n+2
    5) Correct!
    6) Nitrogen = correct, 4 billion years ago = CO2, before plants were able to respire the atmosphere was full of CO2
    7) Hydrogen + a nickel catalyst @ 60 degrees

    Only done notes so far but not memorised them yet.

    1. 2,8,6
    2. Hydrocarbons
    3. Bottom
    4. Alkane - CnH2n+2 Alkene - CnH2n
    5. Inner core, outer core, mantle and crust
    6. Nitrogen is the most abundant gas now and was it Carbon Dioxide 4 billion years ago because of a lot of volcanic activity
    7. Hydrogen gas

    How are you feeling for this exam?

    3) Why is crude oil separated into fractions?
    4) Name the products, when ethane, c2h6 burns completely.
    5) Explain why burning some fuels produces sulfur dioxide
    6) Explain what happens in a fractional distillation column used to separate crude oil

    I found it quite easy. I dropped about 6-7 easy marks though so I am annoyed with myself.
