    People out there......please read this. It's a sad story about my chemistry practicals.

    I did paper 34 yesterday. For the first titration, I was super fast. I had already completed four titrations and gotten two values close to each other, while others were struggling with their second titration. But fate played a cruel trick on me. I was soooo happy I had finished the first one so...

    Poll: Which science subject do you find the hardest in as/a levels?

    I find physics interesting and not that difficult, and I love the practicals. I find biology uninteresting and regret taking it. You just have to learn so many things by heart! I used to find chemistry as hard as hell but turns out its easy later. (All this only in my AS levels, after may/june...

    Chem p22

    I did not say anything about equilibrium. Mentioning the word equilibrium would have cost anyone the whole question itself. But i said that number of effective collisions would increase, and hence the rate of reaction, and probably the yield too, for that matter, but its not totally wrong as you...

    Chem p22

    No, the marking scheme usually says 'allow ecf for wrong answer in the previous question' so you will gain marks if your answer is correct, even when it depends on the wrong answer you formerly calculated, or wrote, for that matter. And I think methanol was given as gas in the question itself...

    Chem p22

    Nope, the answer is: a temperature of 600k is a compromise temperature because an increase in temperature would not be favourable for an exothermic reaction, but a low temperature would provide insufficient energy to reactant molecules for effective collisions. (Mix it up, shorten it up, but the...

    Yep, it should be. Many mistaked the enthalpy change of combustion for the enthalpy change of formation and the answer came positive.

    Made lots of mistakes so my paper is full of crosses and sorries but got the answers correct finally except the ph of solution formed when chlorides of si and al are dissolved.

    I think you certainly can discuss this since 24 hours has already passed, LOL!
