    this right here is my motivation to learn those conditions and reagents

    In all seriousness, make sure you learn those reagents and conditions. The A2 Summer exam has a massive list of them, any of which can come up. They're easy marks, don't lose them by not learning them!

    May I ask where to get this list of reagents and conditions? What exactly are they for?

    I'm not sure where you can get them from, my chemistry teacher gave me mine. I think you can find it somewhere in the Chemical Ideas textbook though. They are all the conditions for various reactions, things like alcohol to aldehyde to carboxylic acid/ketone. Carboxylic acid to amines, amines to amides, etc.

    Just looked it up, Chapter 14.2, but as I said, that is A2.

    Hey guys, how can you easily distinguish between nucleophilic substitution, electrophilic substitution, radical substitution and elimination reactions?

    Sub - something is removed. and replaced by something else
    Add- something adds itself to a double bond (reactant loses d bond). and idk about the rest my f332 revision is currently pending- look in the revision guide...

    Really bro? A list? lol just do some papers, but there is always a question on octane number, bond angle and shape, heterogeneous catalysts, absorption and emission and mass spec

    Can anyone help me out this is really bugging me and I know it should be easy:

    2N2O(g) ---> 2N2(g) + O2

    Standard enthalpy change of formation for NO2 = +82.0 kJmol^-1

    Calculate enthalpy change under standard conditions for this reaction
