    For the 3 reasons i put:
    Variable Oxidation state
    Variable Coordination Number
    And Variable Ligand types

    is this right??
    Yep that's whats it put but without the variable bit. I think it'll be correct

    What did people get for the Temperature of the final solution?
    298 - 13.something. Temp change, I got 13, subtracted that from initial (reaction was endothermic) to leave me with an answer in Kelvin...dunno if that's correct though.

    What was the colour of the tollens reagent black? Because its not reacted with an aldehyde so isn't silver?

    Got 905
    348 for something else

    I got +905kJmol-1 for the lattice dissociation of AgCl and I got -7kJmol-1 for the enthalpy of solution one.

    I did..but it was almost a guess as I just looked at how many can possibly fit around with the total Mr of ammonia and chlorine being equal to 6 water or 6 ammonia..didn't use the info in the question like the grams, volume and concentration.


    I got 1:2 but my method makes no sense. XD And yes, I got +905
    I got 1:2 ratio on the last question my Z was Co(NH3)6Cl2

    i did that, but i added the 13 oh well it will only be one mark

    Why did deltaG obey the straight line equation?
    G = y; T = x; S = m; H = c

    Hence, y=mx+c goes to G=H-TS

    tough, tough paper... grade boundaries will be quite low for sure. Did anyone get deltaG = -TdeltaS + 500deltaS for the line?
    and 1.111 something for the ratio - these are my 'unsure' answers

    Wait, did we have to do something with the graph!?
