Any reason you don't do year 10-12?

CM_tutor probably has a better explanation, but generally boiling point is proportional to molecular mass. This is because a greater molecular mass means greater dispersion forces since there is a greater likelihood for a temporary dipole to form. Alkanes have greater molecular mass compared to...

Personally I found those trash but I guess depends on the person.

Ekman although they may be a bit challenging

They aren't explicity in the syllabus, just know that they are constants used for different equations (i.e. force between two wires).

B and C are acids so produce H+. This H+ reacts with chromate to produce more dichromate. A is a neutral salt so wont produce any H+ or OH-. However D is a basic salt so will produce OH- which reacts with H+ to form water. Since there is an increase in conc of H20 equilbrium shifts to the left...

Let u=\tan^{-1}\left(\frac{1+x^2\tan{(2\ln{x})}}{x^2}\right) From derivative calc: \frac{du}{dx}=\frac{4x^3\sec^2(2\ln x)-2x}{x^4\tan^2(2\ln x)+2x^2\tan(2\ln x)+x^4+1} \frac{du}{dx}=\frac{4x^3-2x\cos^2(2\ln x)}{x^4\sin^2(2\ln x)+2x^2\sin(2\ln x)\cos(2\ln x)+(x^4+1)\cos^2(2\ln x)}...

Well another guy asked it a few weeks ago. If you really want we can copy paste the answer here

I dont remember but it involved 12 steps instead of n steps.

My personal problem with Pascal's wager is that there is a 2x2 square for every religion. Every religion rejects every other religion and many of these religions have 'perks' of joining (going to heaven, enlightenment etc.). So really you are only in one 2x2 square out of millions.

This has been posted before and has also been in a BOS trial.

I read somewhere that you said you were a scientist could you elaborate on what work you did?

You sub in -1 can you write out what you got for the integration on the rhs?

True its medicine offers in general

I guess once 2020 annual report comes out is the only way to truly confirm.

Ive also heard it was 3 people. Ranking is based only on atar (not ucat nor interview) so doesn't have as much meaning as people think.

I think thats an AC induction motor try reading up on it.

Lets say the salt is NaCH3COO note the salt has to be a weak acid or weak base. Now Na+ is a spectator ion whereas CH_3COO- goes through hydrolysis as shown below: CH3COO- +H2O ⇌ CH3COOH +OH- Since OH- is created the resultant solution will be slightly basic.
