    Disadvantaged?

    no study for HSC?

    Pretty much the best thing anyone EVER said! Study too much and you get mental indigestion. 90% comes from the class room, you just have to "unlock" your mind during an exam. Like a GIANT book. Thats why you should NEVER study the day before or your brain goes into freak out mode...

    Amount of Detail??

    hey at least you had a teacher!!!!! I don't know what the HSC has been like thus far for all of you, but my exam papers have all been rather indirect and difficult to discern what on earth the question is asking. I HOPE chemistry is NOT like that, otherwise... i resign! but...

    Amount of Detail??

    haha alright... here goes... viscosity in general terms, from somewhere in the darkest recesses of my mind, is the resistance a liquid has to pouring. glycerol has a very large hydrogen bonding capacity. this is why glycerol is very soluble in water. due to the relatively small...

    do we need to know how to test for BOD????

    it depends on whether you want to enter your exam feeling under prepared or over prepared. i always like the latter option, however it is a personal thing. there are a number of ways to test water quality, so if the question asks you to state two or three then you will be laughing...

    HELP!!! please pedigrees

    Sex linked inheritance is a bit confusing, but you have almost got it. the gene/trait is carried on the X chromosome, NOT THE Y CHROMOSOME and there is no corresponding gene on the Y chromosome. Therefore, since males have only one X chromosome (XY), the require only on allele, while...
