Do we need to know additional polymers beyond those provided as examples in the syllabus? Also, we will to know the initiation - activation - propagation - termination process, and is there anything else we should know for the formation of addition and condensation polymers?
How should we prepare notes for Questions on 8.3 in syllabus? Are we meant to have in depth knowledge of ONE chemical process, or just know that if given a chemical process, we need to consider those factors?
Hi,
For the dotpoint:
Investigate the relationship of Kepler’s Laws of Planetary Motion to the forces acting on, and the total energy of, planets in circular and non-circular orbits.
What are we meant to do (or use) for the underlined part (This is almost the exact same as in next DP). Does...
Hi,
Does anyone know of specific overlap (or similarities) in the topics taught for the current syllabus for Chemistry and past? Or questions from past HSC's that will apply to the new syllabus?
Thanks
Hi,
For Conduct a practical investigation to collect primary data in order to validate the relationships derived above
from the syllabus, what experiments is everyone doing? Is anyone doing one that is not finding the horizontal range of a projectile using a ramp?
Thanks
Hi,
In terms of collision theory, why does a decrease in pressure (increase in volume) favour the side with less molecules.
Eg. for an increase in pressure:
The system will respond by reducing the pressure, which is done by reducing the total amount of particles in the system, thus shifting...
Hi,
I have been unable to successfully solve this question:
A biased coin was flipped such that: P(T)/P(H)=q, where P(T) is the probability of flipping tails, P(H) is the probability of flipping heads, and q is a positive integer. Find the probability of flippings n heads before m tails as m...
Hi,
For Q7(a)(iii), how did students know that they needed to sub the left hand side of the inequality into the inequality proved in the part prior, what thought process lead them to that?
Thanks

Hi, I have been unable to do these questions (any help would be great):
1. Simplify sin(x)+sin(2x)+...+sin(nx)
2. Let z^13=w and w^11=z. Prove that Im(z)=sin{(m*pi)/n} if both z and w are complex numbers, where m and n are positive integers with no common factors.
Thanks
Hi,
A fair coin is tossed n times. What is the probability of heads on the
first toss given that r heads were obtained in the n tosses?
Does anyone know how to do this - solution is r/n
