    What you getting on section A, if you get 19-20/20 on section A that should 100% be an A, but an A is normally much lower than 65 anyway so you should be fine

    Like 15~ sometimes I make silly mistakes if there is calculation questions on the multiple choice. Then I could mess up a little bit on section B and not get an A for that paper.:eek: You just been doing past papers to revise for section B?

    hiiii Because the carbon had 3 attached groups I think, so it has 2 hydrogens and a carbon which makes it 3. So it is 360/3= 120 as the angle

    Ow haha I love Free Radical Substitution!

    I think of it as a married couples Cl2.

    The break up and feel free and horny so they want to bang. But they're naughty and only go for taken men/women :perv:

    So Cl. has an affair with CH4 :sad: and CH4 break up :sad:

    So

    Cl. + CH4 --> CH3. + HCl

    So now Cl. has a bae, but CH3 is baeless and horny

    So CH3. breaks up Cl2

    CH3. + Cl2 --> CH3Cl + Cl.

    So now CH3. has a bae, but Cl. is baeless and horny

    BUT THEN :ahee:

    All the singles bang :sexface:

    and live happily ever after

    this is great

    Well I don't know about the current Edexcel spec, I'm not sure if they changed it from when I last did it (2010-2012) but all the hybridisation stuff is stuff I covered in first year of uni and we didn't need to know it for A-level. I'm not sure why you guys would even need to be introduced to it at such an early stage

    I think it just says in the spec we need to know why the sigma and pi bonding occur, something like that

    So the temperature of the Haber process is 298K?

    Why? Because of the standard states and conditions stuff needed for the steps to occur?

    And what catalyst is used?

    Pretty sure it's an Iron catalyst used, but I think the temperature might be alot higher!

    298k is room temperature (25 degrees celcius) and when you think about it, the reaction will require heat energy to get things going

    Yeah lol but you'd just say its because of the orbitals overlapping?
