How's everyone finding year 12 so far? :D

Response to: "Explain how Le Chatelier’s Principle can be used to predict how equilibrium position will shift when the concentrations of ions are varied when the Fe3+*+ SCN–*⇌ FeSCN2+*reaction is at equilibrium. [4 marks]" In the event that there is a disturbance in the closed system affecting...

Ancient history is easy once you understand the scope of your topics. I rate it a 5/10 :p

Response to Question 1: Similarities: The rate of the forward and reverse reaction are equal. The change in concentration for each species in the equilibrium reaction is constant. Differences: The rate of the forward and reverse reaction are zero for static equilibrium reactions. Static...

Response to Question 1: Darwin’s Theory of Evolution by Natural Selection states that new selective pressures introduced in an environment will alter a species’ population based on the species’s genetic variation. Those species with favourable characteristics to tolerate the new conditions will...

I wouldn't recommend it, esp focusing on getting the best marks possible for all your subjects. Only 10 units will count towards your ATAR. However, I am not sure how much French mean to you personally but you are also studying Spanish beginners.

Made a chemistry and biology marathon thread in the subjects section for us 2019 hsc students :>

check you post in 2019 chit-chat section. i replied :3

Let me start us off with some questions :D 1. Explain Darwin's Theory of Evolution by Natural Selection supports the continuity of a species [6 marks] 2. Explain how an organism derives its favourable characteristics [3 marks] 3. Describe the advantages of internal fertilisation and external...

Hey hey hey! Welcome to the HSC Biology Marathon if you sitting the HSC Biology Exam in 2019!  A prior HSC Chemistry Marathon has already set out the rules of HSC marathons. So I am just going to copy the rules from the 2016 HSC Chemistry Marathon (old syllabus)...

I will start off with three questions :> Question 1: Describe the similarities and difference between static and dynamic equilibria [5 marks] Question 2: Explain what an 'open system' and 'closed system' mean and provide an example of each. [4 marks] Question 3: Explain how collision theory...

Balancing chemical equations Understanding and applyingEnthalpy, entropy, gibbs energy formulas Understanding and applying Formulas involving number of moles (n) and concentration (e.g. dilution - c1v1 = c2v2), limiting reagent Oxidation and reduction, constructing half equations General...

If you are confident that you are able to perform well in the remaining subject units (after dropping SOR), then yep drop it. There is no pointing holding onto a subject that you do not enjoy. This will just affect you psychologically during your studies.

Update for OP: I had a scan over the textbooks today. Biology in Focus looks like an overall better textbook than the Pearson textbook for biology. Greater relevancy and scope (for understanding). I recommend BIF :)

Pearson seems like the textbook used by most high school teachers right now. Followed by Nelson's Biology in Focus :)

Of course! :D

I'm proud of you!

DM me. I can provide you with high quality, free chemistry tutoring :)

Yes, good luck! <3
