Yeah ok thanks I sent an email to my teachers, hopefully they'll reply soon . Hows Silberburg and those Physics books going, good I presume? btw can you PM me the mediafire link for calculus again, I'm back home now, thanks
Hi Sy, I was just wondering, for Chemistry, in the molar heat of solution, is it absolutely essential to write soln in subscript for the molar heat of solution or can i just get away with delta H? Thanks
Yes, I recommend papers from Hong Kong and Chinese Mathematics Competitions, they are similar to Westpac but are harder. Other than that you can join a forum called "Art of Problem Solving", it's another forum I use. It has got posters posting the most interesting of questions but of course it's way beyond the HSC. It's more suited to the critical thinking type of questions.
Yeah that's good- I didn't go tutoring either. You're heaps good on the understanding side of things which is hectic.
About the solution -> I'm not sure of the technical stuff (like whether self ionisation is exo or endothermic) but the general gist is right I think. When you guys have done equilbria in Industrial Chem (option), revisit this question because you can understand/explain it much better
Yeah saw that. Though for a proper answer, don't you need knowledge of equilibrium constant? An explanation by Le Chat's falls short I think (though I could be wrong- I haven't actually thought about the question today, I just know the answer haha from seeing it before)
Um the self ionisation of water causes the proportions of hydronium and hydroxide ions to vary, thus causing the pH level of the water to change? Occasionally the pH decreases to 6 before reverting to neutralish?
