    HOW WAS CHEM 42?

    Section B was terrific. Section A the polymer question was horrible. The rest had lots of silly mistakes. Sigh. :(

    Predict the threshold of Chemistry P42?

    Section B was easy. Section A was easy but tricky. Probably 60s.

    chem mcq...

    KC = [products]/[reactants.] KP = p(products) ^ moles / p(reactants) ^ moles.

    Explain the mechanism of ligand exchange!!

    Hmm. You need to be a bit more specific.

    Chem paper 4, applications.

    Okay, I know this is a bit late, but does anyone have any idea WHERE I can read up on applications before the exam tomorrow? The support booklet goes way too much into depth, and what I need right now is like, bullet points and just the jist of everything. Does anyone know of any resource that...

    Transitional Metals Colours

    You should know the complementary colour wheel. The colour observed is complementary to the colour absorbed. http://wiki.astro-wish.com/index.php?title=Chemistry Click on that click and go to "transition metals" to get the complementary colour wheel.

    Chemistry paper 4

    If the paper is going to be 2 hours - does that mean that its going to be lengthier? Or is CIE just being nice and giving us some more time? lol

    Chem P4 nanotechnology

    It IS there. Its come in past papers too. You need to know complementary colours and their approx. wavelengths.

    How was Biology Paper 5?

    Yeah - there was an overlap of information from the planning and the next page. xD. Whoa. Okay. That confused me. That's a bit far stretched, so i'm not sure whether you'd get that right. The estimate question had to do with the graph, yeah. I got that wrong though.

    Hmm, it could be. I'm not sure. What calculations are you talking about? :s

    How was Biology Paper 5?

    Independant was the concentration of sucrose solution, and the dependent variable was the rate of the movement of the droplet. Microscope at high conc of sucrose was a plasmolysed cell, and a low conc of sucrose was a turgid cell. There are answers on the previous pages of this thread too.
