    Which book has better hsc worked solutions?

    Tbh I don't think it would matter that much as all of them would generally have the same worked solutions. But I have success one and that works for me. :)

    Differentiate... Help please...

    You can also do it using the quotient rule (i.e. (u'v-v'u)/v^2) but that would require more simplifying.

    Differentiate... Help please...

    x^(1/2)/x By index laws: 1/x^(1/2) Take it to the top and differentiate: x^(-1/2) -1/2 . x^(-3/2) -1/2x^(3/2) Hope that helps!

    Answer writing

    There isn't really a common structure to follow. The only advice I have though is to learn all the key verbs. It is essential that you address everything that the verb asks. For example if it is an explain question you must state the cause, the effect and make a concluding statement which is...

    Ions identification

    You said anion so I would assume that the unknown anion is phosphate. Phosphate ions precipitate out when the solution is slightly alkaline: HPO4^2- + H20 <--> H3O^+ +PO4^3- So when you add ammonia, the hydronium ion concentration is lowered resulting in the equilibrium shifting to the right...

    Nuclear chemistry question..

    Hey guys! Just wanted to ask about nuclear radiation.. How can you tell whether a radioactive nucleus would emit alpha or beta particles? Is it just based on the heaviness or instability of the nucleus? Thanks in advance! :)
