Year 11 content on 3/4 exam

[nugz]

Does anyone know of any year 11 content that might not have been covered in the 3/4 content again, that could be covered on the exam?

I think a lot of 3/4 is basically based on the foundations of you having completed 1/2. I think anything VCAA will have on the exam will be 3/4 based, with obvious relations to prerequisite knowledge from 1/2 (e.g. in simplest form, balancing your chemical equation). :-)

I think a lot of it just secondary knowledge; mol concept, gas laws, acid/base, intermolecular forces, things like that

Yeah that's what I thought too.
I've seen percentage abundance show up a few times on company exams too though

Like of isotopes?

yeah calculating RAM using RIM, but I highly doubt that'll be examined (although it could)

Isn't it just (percentage abundance * isotopic RAM)/100.

Um what's isotopic RAM and RIM

It's year 11 stuff
Relative Atomic Mass which is like 63.5 for copper
and Relative Isotopic Mass which is like 63 and 65 for copper.
63.5 is the weighted average, known as the RAM

yeah exactly.
