    Industrial Chemistry.

    it was at 2000 degress. K was 2450 i think. oh and they gave u the equation for K The last 7 marker was kinda tricky. ANd the modelling was hard, apparently we were supposed to use the decomposition of nahco3 into h2, n2 and na2co3.

    What did people get for the mercury question?

    0.228 ---> 0.23 u use the graph to get 0.17mg/L then convert to mg/kg (since volume wass 0.025L and mass 0.018 or something)

    Impact of DET laptops

    Impact of DET laptops

    hmm.. im just saying, since most of our grade has used these laptops to take down notes, email essays and keep track of work. I know its improved my study a lot, since I can browse past papers, online notes and read pdfs (i didnt have a laptop b4 then). Sure most ppl bludge around on them, but...

    raw mark

    generator question lost 1 mark, tower question lost 2 marks, accuracy question lost 1 mark, projectile lost 1 mark, maybe 5 marks for sillies, looking at ~90. What would that scale to?

    transmission question

    wut, remember, 1 million watts in an MW and 1000 watts in a kW Energy loss in superconducting wire = 3kW x 100 = 300kW = 300000 W Energy input = 100 MW = 100000000 W Efficiency of C = (1 - (300000/100000000)) x 100% = 99.7% therefore efficiency of C is 99.7% while B is 98.4%, therefore C is...
