    Chemistry Question HSC 2007

    Sometimes they give you solubility table, sometimes they don't. It's best to remember it. I think it's a syllabus dot-point anyway. It's really not too hard to remember. 20.a) Anode is the electrode where oxidation takes place. Oxidation means loss of electrons. Thus, anode is Pb(s). To write...

    combustion of fosil fuels

    H2O. Complete combustion will give CO2 and H2O. Incomplete combustion gives C + CO, and no CO2, but still would give H2O.

    builders for detergents

    Builders have to be added because anionic detergents do not lather well in hard water, which would form scum.

    Basic acid/base questions

    It's just that H+ ions can never exist on their own. They have too little electronegativity, so they almost instantaneously sticks to a H2O particle to form a coordinate covalent bond, forming H3O+.

    Music 2 or IPT - which one scales better...

    Music 2 is way harder than IPT. But if you've got confidence in Music 2, keep music 2, since it does scale a lot better than IPT.
