VCE Chemistry 2010 Unit 3 Exam Suggested Solutions

[kenhung123]

this is great, however in Q9 if it is the first fraction why should methanol/ethanol not be present as 97.2 is above their boiling point, i thought they would just rise through the fractionating column and be collected in the receiving flask therefore being present in the first fraction

Yea that is so tricky! The referred mixture as the thing that is still in the flask! not collected! Yep, hard feelings..

you have suggested solutions from examiners?

so many teachers are examiners, maybe two at his school is? i know my teacher is an assessor this year, and also the other chem teacher might too. i'm going to speak to mine on friday about things, maybe they have already got the assessor's suggested answers....

Yeah I believed him, I was just surprised he didn't share! lol.

But even then, examiners can't teach, assessors yes but not examiners .

Don't examiners write the exam?

[Studyinghard]

tbh this exam was probably worse than last year. not because I think I did bad but more so because it didn't test about your level of chemistry but more about how many tricks they tried to fit into the exam. Feels like their main intention wasn't to test our chemistry knowledge but more to pick the ones who make the silly mistakes.

Don't examiners write the exam?

exam writers write the exams, examiners mark the exam ?
errr...

lol I always thought (heard) examiners write the exam (hence they examine us lol) while assessors mark them (hence they assess us).

I thought assessors write the study design/exam and therefore can't teach.

examiners just mark the exam according to a set of marking criteria they are given after the exam, so they can teach.
and examiners don't have to be good teachers or anything.  both of my awful english teachers mark exams, as well as my chemistry one who didn't know the rules for sig figs... *sighs*

Our school has 2 examiners for Accounting.

One is the best, the other is the worst.
