Find the H+ conc. Minus it from the molarity of the solution. then divide it by 0.1 because that's the original number of moles to find the ratio.
re: HSC Chemistry Marathon Archive
yeah, But I'm just doing past papers so that everything is fresh in my mind before the exam. From tomorrow arvo, CHEM 24/7. lols i love chemistry.
my min is 64 and max is 74 so i really do hope that the cutoff is not too high this year.
Everyone in our school found it hard and we usually have around 15/30 e4's
There was actually not much poly at ALL. Freaking poly was so easy and they only gave around 5-6 marks of polynomials. Overall i think it was very biased towards complex/conics/mechanics in comparison to last year.
OH AND harder 3u.
