I understand that at Ksp we have a saturated solution which is where you have the maximum amount of solute that can dissolve in a given solvent but multiple people are saying different things. Some people are saying there is no precipitate and some people are saying there is a precipitate. I am...

Can anyone please explain this in terms of emf and induction...? PLEASE🙏🙏🙏🙏

My teacher said choose something I'm interested in and that for me if Visual Arts. I finally decided I want to research paint but I have no idea how to approach it. I'm finding it complicated to understand the theory and have no idea how I can even make a quantitative experiment out of it. Any...

Answers say C I think it has to be A. Someone pls come to the rescue with the correct explanation.

I am a bit confused about the mass defect occurring from nuclear fission/fusion reactions. Online sources + textbooks say that the products of a nuclear fusion reaction will have less mass than the reactants, and will release energy in relation to E=mc^2. But in my matrix book, they are saying...

Hi guys, This is probably me just stressing out about random and irrelevant stuff but am I the only one really lost about what I want to do after high school. I 100% know that I want to go to uni but I don’t know what for. Me picking subjects for the hsc based solely on what I like probably...

Context: I am currently doing Science/Law and majoring in chemistry. I should still able to change to Arts/Law and major in music. I have a fervent motivation to do both chemistry and music, however, my passion for music slightly trumps that of chemistry. The reason it is a hard decision is...

Hi everyone, I hope you are all keeping safe and well. :D I am Peter and I graduated last year with a 99.70 ATAR as an all-round achiever, with HSC marks of: 97/100 in Physics (Ranked 1st Internally) 46/50 in Science Extension (Ranked 1st Internally) 99/100 in 2U Maths (accelerated) - NEW...

Got my first bio assignment for year 12, but I'm too overwhelmed with things that i could possibly do e.g. practice papers, extend notes, get straight into memorising. What should I be doing from now up until the exam and how should I structure my day in terms of fitting in the assignment into...

hi omg my subject selections are tomorrow!! i've thought out my subjects for a while and i plan on: ext eng ext math jap continuers chemistry bio But I've been getting cold feet for biology, is it really worth it doing two sciences?? Because everyone I know says that biology is a death trap and...

Have you done or are currently doing Physics/Chem/Bio for hsc? Do you regret it? Did you enjoy it? What was it like? How did you handle the workload? Was it worth it and was it difficult? Tomorrow is the last day before subject selection and I'm still unsure about exactly which science...

I'm going into Year 11 this year at a top selective school and I'm taking the Asian Five (Ext Maths, Adv English, Chemistry, Physics and Economics), plus Geography. My school only lets me choose up to 2 sciences. After speaking to some people who have graduated recently, I've heard that physics...

Anyone got their scaffold of how they wrote their project’s proposal? Or any tips on how to write it?

contemplating whether I should do physics or biology, I want to do bio but like everyone tells me its scales down and heavy content and it's really easy, but Ive just been introduced to physics module 1 and is so confusing with velocity, displacement, finding time, acceleration with 3 weird...

Hi! So for a task in school, we have to design our own experiment but I've spent hours researching and can't find anything. Does anyone have any ideas for experiments I could do???? Please this is urgent. You will complete an investigation, in groups, to explore the equilibrium of carbonated...

If anyone has any of these physics for 2020 with solutions, please dm/pm me, I need to check if I got my answers correct! p.s ik its intellectual property, but if you could just dm/pm me the stuff through, greatly appreciated yoooooookkkkkkkkkkkkkkkkkkkkkkkk

Hi Guys, I've been looking at the Year 12 assessment schedule and at my school the prac is worth 40% of internal marks. This year for chemistry, because our school was shut down, our practical assessment task was just at home and we had 2 weeks to do it, so I'm not too familiar with how it...

Hi, I need some year 10 Science papers for Genetics and Evolution, Chemistry (chemical reactions), ICAS/REACH and possibly physics (motion) to use for home learning. Thanks a lot!
