What mark do you need in chemistry to get a decent atar of 90+?
Your
ATAR is dependent on
all of your subjects. If you got 100 in chemistry but only 50 in everything else then it was all for nothing (except maybe a glorious state rank).
What mark do you need in chemistry to get a 90+ ATAR? Think about all of your subjects all at once, not just chemistry.
Does anyone have an easy method of memorising solvay process?
This is probably one of the most rigorous things to memorise. The reason is that there's heaps of processes that go on in the Solvay process.
I would recommend the following three:
- A flow chart
- A list of chemical equations
- The steps, in your notes
You should read over your notes ample times so that the steps are actually presentable, however it may be too hard to process. Hence, utilise the flow chart and compare your notes to the chart. The flow chart gives a much more visual instead of mental approach to the things at hand.
As for the chemical equations, you may choose to put the equations ON the flow chart as well, but you may choose to just write it out under a subheading
E.g. Brine purification: ...
Decomposition of sodium carbonate into sodium hydrogen carbonate: ...
(I'm fairly sure there are 6 subheadings if you take this approach)
