I think it's because of the way they define the enthalpy of neutralisation in the HSC. It is stated as the amount of heat energy released from a neutralisation reaction when 1 mole of water is produced at 25 C and 100 kpa. So the definition they use is deltaH neut = -q / n(H2O) Based on that...

The bond exists between the two carbons. The hydrogen are then bonded to the top carbon. They are not connected to the CH carbon Therefore it is incorrect to draw the 2nd one because it implies there is a bond either with the carbon or the 3H

it's B there is an easy way to do these questions by the way if you didn't know. 1) move all bonds not C=C to vertical positions 2) open double bond up 3) repeat the exact same structure 3 times to show the continuation

I would probably make the same decision, because in my school a lot of the practice we did anyways was from exam questions rather than using the textbook that much. Since the teachers put together documents and stuff of HSC questions or assigned exams for homework. Because of that it would still...

I would wait and see what you get in the HSC mark for it. If you end up getting close to the 95 then I wouldn't probably risk it because they don't take your best mark out of the 2 years. If you repeat whatever you get the 2nd time will be your mark, so it won't be worth it for gaining maybe 2...

Have a look here: https://boredofstudies.org/threads/q-regarding-non-equilibrium-systems.396702/ It is not really linked explicitly to entropy and enthalpy. It is about activation energy

You need to know their structure, how they clean things (analysis in terms of intermolecular forces, micelles, hydrophobic, hydrophillic etc.), advantages and disadvantages of each (such as why would you use a detergent over a soap which is because of hard-water or environmental impacts of soap...

Equilibrium is referring to a reversible reaction (one with double arrow) Non-equilibrium is referring to a irreversible reaction (only has forward arrow). This is essentially your complete reaction or standard reaction you learnt about throughout Year 11

You have to be honest with your group members. It might seem awkward but you need to call out the person if their work is not up to par because in the end if you don't it will lead to a bad mark for everyone, that's part of working in groups at uni. However, there's no need to be super harsh or...

It is good to aim high and that is the main thing your parents are trying to say. You should keep in mind sometimes parents say things to try scare you into working harder, it's not meant to be like a put you into a state of doom. You are thinking in a way that is at both ends of the extreme...

For equations just pick any fuel for combustion like octane (C8H18) for example. Photosynthesis is an equation you have to memorise. Whether a reaction is irreversible or reversible depends mostly on the activation energy (the minimum collisional energy required for a collision to break bonds...

The mark you get in the HSC exam is yours. That will be your external mark, there's no link to ranks with this. You can be ranked 20 and get the top mark if you get it in the actual exam. However, this won't be the same as your internal mark, which is where the ranks will be factored into it...

Firstly, to answer the specific question, the answer is wrong it should be 14. Although the above method mentioned is correct. It would take too much time to do that in an exam and you would have to memorise something like that for different types of molecules like alcohols, haloalkanes...

There's no way to know what the average wam is. There isn't any like published data saying this is the average wam in each degree. Only real way I guess you could find out is by asking some senior lecturer or someone in the uni school, what is the average.

I made a post about this before for things you need to know from Year 11 going into Year 12: https://boredofstudies.org/threads/chemistry-new-syllabus-advice-sample-answers-by-an-experienced-hsc-tutor.388479/#post-7314798 The one thing I didn't include in it is for Module 4, you need to know...

I didn't mean it in that sense. I was just saying generally I used either multiple quotes or a combination of quotes and a different form of evidence in analysing the texts. When you analyse a text there a variety of things you might use to support your argument. The obvious one is quotes for...

I don't remember exactly because I did HSC around 5 years ago. The way I answered questions was a little different, I would take multiple techniques on small quotes to show a theme or concept, so I had multiple evidence or quotes for each thing.

One per mark is the standard that most teachers say. It doesn't mean you have to only do 1 per mark, this is the recommendation based on you have to space out your exam time accordingly. If you have more time and can think of more things you might as well write them in. I remember in my english...

I enjoy my course, but once you are at uni it is not like high school, where your primary focus is studying. At uni you may be balancing many different activities while studying such as internships, job, social life and exercise, so it's natural that sometimes you will feel overworked and need...

To be honest I didn't really have many slumps during HSC because I was highly motivated at the time from the several factors I mentioned in that post. However, at uni I have experienced slumps sometimes. You have to force yourself to start studying and after that usually the urge to...
