URGENT- Production of Materials chem prac Exam - what was yours/what could it be? (1 Viewer)

Hi everyone!

please help!!

Got a chemistry POM prac exam , we get no clue concerning what it's about, but could be from any of modules 1 - 5 in production of materials.

To current/finished HSC students: what were your exam pracs on this topic?
any details very much appreciated,

or if you actually have the paper/ question that would help sooooo much!!!

p.s. if u have the paper/ or remember about the james ruse past practical - doubly appreciated

THANKS!

If it was going to be from that topic I would say it would be the alkane/alkenes prac exam as that is a very common experiment that is asked in the HSC exam.

Know stuff like, what the result turned out to be, why it turned out that way, the procedure, what materials you used and why you used them

Ours was to measure the heat released by burning liquid alkanols by measuring the heat absorbed a water in a calorimeter suspended above the spirit burner containing the fuel using q = mC (change in T). Then calculate the molar heat of combustion for each fuel using molar heat of combustion = q/n.

Discussion questions usually ask about sources of error in the experimt and how these could be reduced.

Thanks! Anyone else???

Anyone have kind of tricky pracs, like identifying X, Y, Z substances by carrying out a prac and observing properties, like if you were given electrodes A B and C and had to name them after figuring out their electrical potential?

Thanks.
