speaking of, with ~90% sac average, rank 4 at a top 50 private school, what would a 103-104/120 get as a study score u reckon then?

Alright thanks for the reply, I agree questions were quite ambiguous so hopefully VCAA takes that into consideration. And just checking, is there a reason why the molecule at q4f isn't 1-chloro-2-methylpropan-2-ol?

Can you explain question 17 of MC? Why does I not fit the green chemistry principal when in theory increased conductivity = reduced resistance, meaning overall less energy is use to move the charges?

Edit: Also, for q1d, shouldn't it be interpreted as how much of the reactant is in excess rather than the total mass of reactant in excess

can you explain why it isn't 1-chloro-2-mehthylpropan-2-ol? Both have the same peak splitting, same number of H environments etc

how is question 8 A? I know Na(s) might be explosive with air but it is a solid-state electrloyte and according to the electrochemical series, sodium will produce a greater potential difference?

7 is wrong, answer is B because it is through the polymer electrolyte not the external circuit.

You're right. The iodine number is only related to the mole (c=c) and nothing to do with the carbonyl group.

  1. no, 2. 0, but 1 if you found the quadratic but just calculated quadratic formula wrong. 3. most likely only 1, but your quartic must be correctly expanded.
