Yeah I have a really bad feeling for chem as well so I'm trying to cover all my bases. I'm hoping for heaps of calculation questions, i'm expecting I'll get asked on the batteries and lots of chemical monitoring and management where I'm weakest.

What I generally do when a question asks for compare is that I draw up a table with all the relevant info in it and then just incase I add in another column along the lines of similarities/differences/comparison just to make sure they can't take marks off me. I think the table is better because...

We had 5 minute speeches for trials, most people's were approximately 800-1000. I find the easiest way to do it is to time yourself reading an article from a newspaper aloud. Then count how many words you spoke and then just add another 100 because under pressure you'll speak faster.

Thanks for rep. Glad the list helped.

C. In a proper titration for this the burette should be rinsed with acid, the fact that it is not means that the acid will be slightly diluted by the water, reducing its concentration. The conical flask should also be rinsed with distilled/deionised water rather than the base solution. As it is...

Syllabus comes first. I just compiled this from the past papers I've been doing.

Industrial I'm using Na-24 which emits radiation and has a 15 hour half life. It is put in pipes/watersystems/etc and they go along the pipe with a geiger counter or whatever and when radiation is detected they find the leak. Its good for this because of its 15 hour half life which means that...

Thanks for rep. Glad it helped.

I would agree, this checklist was really made for me and I have done a solid amount of study for chem so there's stuff I take for granted. These were just for questions I think that may be more than 3 marks.

Hey guys I made a checklist for chem that you guys could use as well: POM -Alkane/Alkene Experiment -Biopolymer -Alpha, Beta, Gamma decay -Radioisotopes (Medicine+Industry) -Dry Cell or Lead Acid cell and Button Cell or etc -Combustion of alkanols exp. -Production of polymers (PVC, Polystyrene...

Sleep it off. Wake up early, study. Works for me.

I love this. I will attempt to remember it.

I know that. I'm talking about testing for cations and anions with precipitates and flame tests. Can you help with that at all?

I did bio. The test was nothing like previous years, it was all focused on skills. The 7 marker was on an increased understanding of biology and its implications for society, I don't know what the chem equivalent is to that.

Biopolymer: Polyhydroxylalkanoates (PHA) -Created from Alcalingenes Eutrophus -Its biodegradable property is suitable for its uses in nappies as it makes them disposable without damaging the environment. Predictions: -Water treatment 6/7 marker -Radioisotopes 4 -Esterification experiment 8...

Hey guys I really struggle to remember these does anyone have any decent ways to remember them?

Thanks for the rep. Don't stress about ancient, you don't have to do ever again in your life anyways.

Thanks for the rep.

I had one reference to the source. Maybe I should have been capped a bit more but I had a good arguement that got me through that.

Hsc fat. Never liked gyms like fitness first. Go to my rugby club gym occassionally but mostly do dips/push ups/crunches/etc at home combine that with running it keeps me in shape.
