    Chemistry Urgent Help

    1) find concentration using c = n/v and n = m/MM. After use c1v1 = c2v2, as a dilution is occurring This represents concentration of Na2CO3. As each Na2CO3 contains 2Na+, this means the final answer will be c(Na+) = 2 x c(Na2CO3) 2) deltaH = bonds broken - bonds formed bonds broken is...

    how many hours of study

    No didn't really enjoy english in the sense of how HSC structures it, but in general I could appreciate the interest in terms of analysing a text and people gaining different perspectives based on their own intepretation. I liked the outside of the exams, analysis part but yeah exams for english...

    Chemistry help

    a) c = n/v. v = 0.5 L, you need to find moles from the m=50.0g use n = m/MM should get n = 0.202... moles c = 0.40048... c = 0.400 mol/L (3sf) b) Dilution questions always use c1v1=c2v2 c1 = 0.400 mol/L, v1 = unknown find c2 first, c = n/v, where v = 1 L use n = m/MM to find moles using the...

    Chemistry Help

    deltaH =-ve as the reaction is exothermic and releases heat to the surroundings. Entropy is a measure of the disorder in a system. Here the reactants have more entropy because there are more particles than the products (2:1). This means entropy is decreasing, so deltaS = -ve deltaG = deltaH -...

    Yeah but a lot of schools ask the students for their ATARs after because they publish them in like the school annual report or some type of newsletter/website post. Obviously though with that it's not like compulsory but most people if they did well would probably let them know.

    Normally ATAR for most schools. Usually some kind of ceremony for high achievers like the following year after atars released at most schools

    Advice for going into Year 12

    People over exaggerate things most of time whenever they are describing their experience. It's to just reiterate you need to work hard, rather than literally meaning you won't even have time to sleep or have some amount of free time. It is true your free time won't be as much as before, but then...

    how many hours of study

    Relaxing time was mostly while eating, that's why I would eat and do stuff for like 1 hr. I can't remember exactly since it was 5 years ago but I probably just watched youtube along with it when at home. I had a very high tolerance for being able to study without breaks for long periods of time...

    Hoping for a 91-94 atar :/

    It may not be as high as 94+ ATAR but there is still the possibility to get 90+. This however, means you need to do pretty well in the externals. Since you have 10 units and biology will count it's important you improve this mark as it is significantly lower than the others and so will drag you...

    hi year 11 chem help pls, exam tomorrow.

    Two formulas are used in these questions: q = mcΔT ΔHc = -q/n(fuel) Always first should assign the values in the question to variables: m(C2H5OH) = 1.275 g ==> n(C2H5OH) = m/MM = 1.275 / 46.068 = 0.02767.. moles m = 100 g = 0.1 kg ΔT= 14.4 C c = 4.18 J/g/C ΔHc = -1364 kJ/mol (this should be...

    Should you handwrite or type notes for year 12 or both?

    Doing a combination of both is best. In HSC, personally I made notes digitally first because the first time you write something down it's probably going to have a lot of excess information and maybe exclusion of certain important details required in responses. That way after I made a first...

    Chemistry New Syllabus Advice / Sample Answers by an Experienced HSC Tutor

    Saponification as a process was required knowledge in the old syllabus as there was a specific syllabus dot point about knowing the method. The structure, action and uses is what the dot point states in the new syllabus. It's still a good idea though to have some knowledge about the process. You...

    Good atar minimal study

    Even if someone had the intelligence to study 2 weeks prior and do that, it's not possible because of how the HSC is structured. If you haven't studied properly prior to HSC then that means your internal marks will probably be low and so it will be impossible to even get close to that ATAR...

    Advanced Mechanics

    If you derive it then yeah you would probably get the marks, but like lets say for example it's a 4 mark question and you just quote an equation without deriving it and your working is like 2 lines, you probably won't get the full marks. It's similar to how in maths the working is important to show

    Advanced Mechanics

    The problem with using these other equations is that you run the risk of if you get it wrong you might not get many marks, because there is not much working associated with them as they are already derived relationships. All the questions in HSC Physics can be solved using only the formulas...

    improving in year 12?

    It's possible to do well in Year 12, without doing as well you want before. The main aspect in getting a good ATAR is consistency. The rest in terms of how people study is personal preference and will work for them but may not work everyone. The most important thing is actually putting in the...

    How do I best prepare for year 11?

    Some subjects you can learn ahead easily by yourself or with help of a tutor. These ones are 3u maths and the sciences, for these it might be a good idea to go ahead and try learn some of the first few topics (maths) or first module (sciences) by using textbooks your school has assigned. By...

    Scholarship Documents

    It varies with each uni. Generally speaking there aren't any scholarships that are solely academic (aside from the ones that are like for a 99.90+ ATAR). Most of the ones stated as academic you still need to answer a range of questions from my experience at applying at UNSW. These questions...
