Either B or A.
I dropped from Pure Chem to Combine Chem around October.
At first still quite scared,
after doing the paper, i was shocked. It was quite easy in my
opinion.
To find Speed of Reaction, just calculate the amount of gas
produced/min. Add magnesium into Conical flask, use rubber bung to
pass gas produced into calibrated Gas Syringe. Measure amount of
gas produced at 1min,2min,3mind,... to 5 mins.
Previously in Pure Chem do before designing experiment, so i'm
already prepared for this question. So relatively easy for me.
The only questions i sucked at = Q(A), Mole and the next stupid
Alpha, Beta, Gamma shit...
The rest all quite simple for me.
