Well, I've decided to keep chem (not that I had much choice)
But I figure as I'm doing it, I might aswell put in some effort ... And that may mean a lot seeing as I got <20% on the Unit 1 exam
Though I need help. My question here is, which prior knowledge from Unit 1 is needed for Unit 2, and more importantly for Unit 3/4... And which of that knowledge is not needed at all....
I need to know so I can get busy these holidays firstly trying to catch up, then trying to get ahead
I have copied the list of what is needed for Unit 1 (now I need to know what we actually need to know for Units 2/3/4 or what would help)
Unit 1 CHEMISTRY
The Periodic Table
historical development from Mendeleev to Seaborg
trends and patterns of properties within The Periodic Table: atomic number, types of compounds
formed, metallic/non-metallic character, chemical reactivity of elements;
atomic theory
historical development of the model of atomic theory with contributions from Dalton to
Chadwick
limitations of the model of atomic theory
mass number, isotopes, calculation of relative atomic mass, electronic confi guration including
subshells;
the mole concept including empirical and molecular formulas, percentage composition, Avogadros
constant;
interpretation of data from mass spectrometry.
models of bonding to explain observed properties including melting temperature, electrical
conductivity, chemical reactivity, shape, polarity of bonds, intermolecular forces
metals
ionic compounds
molecular substances, network lattices, layer lattices;
limitations of the bonding models;
properties and systematic naming of alkanes and alkenes up to C6;
structural isomers of C4H10;
behaviour of surfaces and the application of surface chemistry in nanotechnology;
addition polymers
relationship between structure, properties and applications,
synthesis, cross-linking
development of customised polymers.

Or if thats too much, then just list what we definately DON'T need :D
Or what is most important to know from that list :D
-
I think you pretty much need to know everything there for 3/4 chem lol
-
Addition polymers: only need to know about the structure and the chemical bonding.
- do not need to know applications, synthesis, cross-linking and development of customised polymers.
Applications of surface chemistry in nanotechnology - don't need.
Historical development of the atom - don't need, but it's an interesting history lesson to read over.
Historical development of the periodic table - don't need.
For covalent molecules, you do not need to know about network lattices and layer lattices.
You will need everything else!

Now I know thats not true, because Im positive we don't need to know all that history stuff about the atomic theory etc....
Can anybody actually tell me which stuff we REALLY need to know/don't know

Thanks
Just to clarify, do we NEED to know about the mass spectrometer
-
you'll go over it again next year so you don't NEED to know it at this point.
basicly, all you really need to know for both unit 2 and year12, are the calculations (mol, etc) and bonding. (covalent, ionic and hydrogen especially)
OH and organic chem. It's good to know that shit even though you'll touch over everything you did this year again next year before learning new shit.
-
in year 11, you want to absolutely pin down:
basic stoichiometry [unit 2]
basic organic chemistry [unit 2]
basic reactions [unit 2]
redox reactions [unit 2]
equation balancing [unit 2]
basic volumetric analysis [unit 2]
basic gravimetric analysis [unit 2]
gas laws [unit 2] (well, just one of the gas law)
otherwise unit 3/4 will be a huge struggle
so... what is unit 1? its basically foundation knowledge so you can understand unit 2 [the actual chemistry]
and this background knowledge and understanding is continuously drawed on throughout unit 3/4
so how much you need to know is really how well you want to achieve.

Just don't let the fact that it's OMGCHEMISTRY overwhelm you. Often, if you find a question very difficult, if you sit down, and then pull it apart into steps, it becomes very simple. A lot of Chemistry questions tend to give you long paragraphs of information, I know this intimidates a lot of people at my school, but if you pull it apart and focus on one step at a time, Chemistry is quite easy.
The stuff that isn't calculations is just memory. Read and review and review and review and review.
...and review

Wouldnt the study design specifiy what you need to know, not know?

not everyone can go on to read the study design without falling asleep or losing the meaning of the document to some degree.
plus, the study design does not tell you what previous knowledge it draws on, or what underlying principles are behind the new contents.

The dot points are quite vague on the topic of what to study. For example, in Unit 3, one of the dot point refers to the Principles and Applications of Atomic Absorption Spectroscopy. It doesn't really give detail of how much "Principles and Applications" you need to know.
-
Yes mass spec is in the unit 3 course but you can just learn it next year
