    Do you like it? Does it have the little mini quizzes in it like the physics one does?
    I'm just trying to work out whether it would be worth my while nipping down to the library to borrow a copy or if I should just focus on my revision cards/past papers at this point.
    I'm not sure whether it would make a significant difference, after all both textbooks are authorised and presumably have to contain all the content of the course.

    As for small tests, they have the quick questions at the bottom of the page but they are really simple and have no comparison to the exam questions. They do help re-iterate knowledge though!

    And you know how in the Physics book they had a 'Test your Knowledge' page at the end of each topic, well the Chemistry book doesn't have that because there is a lot more topics. It just has the small ones at the bottom of each page.

    It's still good though, it's worked for me since S3!

    Thank you!

    I don't think I'll go out of my way to pick up a copy then- sounds roughly like the one I already have! Although I do like the end of topic quiz idea- it's good when you are revising in a group.

    Is it not called the mass number?
    Yes it is. But the question was what is the same elements with different mass numbers called or something like that.

    I've almost finished revising the whole course! Only got to go over Ionic Formulae, Bonding Properties and Fuels/Hydrocarbons and then I'm done and can move on to Past Papers!

    I just go straight to past papers and when I trip up on something I learn it. Although I have a chemistry tutor It doesn't mean I don't need to work hard though

    I have had a total of 7 chemistry teachers for the course of my standard grade + a whole bunch of suppply teachers. The joys of going to a Sottish state school..... :unimpressed:

    I borrowed the standard grade textbook of one of my friends who sat her standard grades last year and it was pretty good. Past papers are also an amazing method of revisision. There's some recurring things and some patterns in the layout too.

    Being as geeky as I am I actually enjoy doing past papers

    I also really love chemistry I think its really interesting and just genuinely enjoy it.

    You feel like a boss when you know everything in the course and you are just whistling through every past paper :ahee:..

    I also love doing past papers I'm not yet bashing through them, but I'm close
    So I'll hopefully get a 1 :cool:
    Do you choose Chemistry for next year?

    Ive got a blue chemcord book, the small one.

    A big red hodder and gibson one.

    Loads of others which were passed down,

    I prefer the small one due to the precise notes it gives.

    How y'all doing in revision? Not been on this in a few days !

    I did I didn't have a choice tbh as I want to do Veterinary Medicine at Uni.
    But I like chemistry so it's not a problem for me.

    Music revision for me today and I'm starting hardcore chem. revision tomorrow

    Likewise, you get pastpapers which depress you to the max but chemistry one I enjoy, it was the same with physics.

    Jeez im such a weird child!:rolleyes:

    Try to master all the calculations and graphs/predictions etc, they can give you a good 8 marks in the exams!

    Can someone walk me through a calculation and give me a bit help.

    It's these ones that are the only ones i'm having slight trouble with.


    (c)The average volume of sulphuric acid used in the titration is
    20 cm3
    .
    Calculate the number of moles of sulphuric acid used. (this is into a 10cm3 solution of potassium hydroxide by the way).



    AND


    (d) H2SO4 + 2KOH > K2SO4 + 2H20

    Using your answer from part (c)(, calculate the number of moles of
    potassium hydroxide in the 10 cm3
    sample of potassium hydroxide solution.

    Heyy I've got the exam as well, 6 days and counting :/ how is everyone getting on with revising? I am doing General past papers and getting 3's each time and mostly 2's in the credit but I would like a 2 anyway and your practical grade earns you a 1 if you have a 1,1

    Anyway a guy came to our school to talk about revision techniques, I have highlighted nearly all of my success guide etc and its sinking in, I got 4,4 in prelim so you can see I'm improving aha. And he also said if you spray your hand with an aftershave/perfume and smell it every now and then when revising then spray the same aftershave/perfume on the day of the exam some memories will come flooding back before smell/taste holds the strongest memories.

    So uh...yeah, thats that, I can't do that though, I have a cold lol

    I looked up the past paper, 2011?

    (c) Well, if you look at the wee diagram of the titration set up, you'll see that the H2SO4 conc. is 0.1M.

    you know that n = c * v(litres)


    Therefore:
    n = 0.1 * (20/1000)
    n = 0.002 moles



    (d) Use link-proportion

    If 1 mol H2SO4 reacts with 2 mol KOH
    Therefore, 0.002 mol reacts with 0.004 mol KOH

    So the answer is 0.004 mol KOH
