    Are the HSC modules for Chem similar to each other

    So in Year 11 now, and the Preliminary Modules are somewhat similar to each other. I was wondering if the HSC modules are like this, or more similar to each other or less similar to each other. To those who might not understand, an example is the physics prelim modules; they're not similar...

    Are the HSC modules similar to one another?

    So in Year 11 now, and the modules: Moving About, the World Communicates, Electrical Energy in the Home and the Cosmic Engine are barely similar to each other. Compared to Preliminary Chemistry's modules, they are not similar to each other at all. I was wondering if this is the case in HSC...

    Should I take 4U maths for year 12?

    So it's nearly the end of Year 11, and 2U maths is my best subject (full marks so far in the assessments) and I've finished and understood (to an extent, but perhaps forgotten some things) 3U, but I haven't yet mastered 3U like I have 2U (which I did last year). I'm just beginning 4U at my...

    How do you find the Valency of Transition Metals?

    I know for some such as Iron and Copper it's stated in Roman Numerals, but I also know there are standard ones as well. For example: Silver is +1, Nickel is +2, Zinc is +2. Does anyone know more standard valencies, or where I can find all of them?
