So far in english it has been largely impromptu writing caused by panicking and partial blank outs when writing essays in exams. Also dont have much experience in adapting essays so during a test when a different style of question comes up it causes that cycle of forgetting a significant amount...

My current dilemma is whether to focus on improving my english rank more than my other subjects or should I focus on my other...
Read the question properly.
So the person who titrated the base with the known acid only used 25mL, not all (250mL) of the base, hence that is why I used 0.025 rather than 0.25.
Chemistry > Biology or Physics in terms of the syllabus and overall personal experience :3
Biology > Physics if you like to remember really long intricate concepts and dislike calculations (albeit there is a very small amount of them still i.e. punnet squares....but yea just squares...)...
Integrate y=x^3 dx where the boundaries are x=p and x=0
then you get x^4/4 (no plus c as it is definite integral )
sub p in to get p^4/4 which is area under curve.
area = l x b
l = x
B = y
hence to get y sub p into x^3
Therfore your final asnwer for rectangle area will be p^4...
The judgement of monoprotic was determined by the community. I just assumed it was carbonic acid, although this may initially cause the change in ratios, the fact that people say it is monoprotic ensures that it only ionises once, and essentially does not affect the ratio of acid to base.

Why is everyone saying the POH is 3.5? the pH is 3.5...
Because when you are calculating the titration question:
C(a) x V(a) = C(b) x V(b)
And you calculate that C(a) = (0.0083*0.0095)/0.250
^that is the concentration of the acid, not the base....and when you -log(base 10) (H+ conc.) that is...
Generally compare with the answers of success one and dot point etc, but in some cases the answers presented in these books are not that great really, so if that's the case either head to the BOS marking criteria and mark it yourself (however this is somewhat bias and can be both...
3 would be guaranteed provided the others are mid-high 80s. I think 0 is still possible if everything is like 88-89. But to be safe at least 2 b6 and the rest high 80s (87+)
For both 90 and 95, 0 band 6's will still get you there as long as all/most of your subjects are high 80s and have decent scaling.
EDIT: In your case, I agree with photo for 95+ 3 would be suffice as long as your other units are in the high 80s.
