Russian Roulettes

Russian roulette is a life and death game that involves traditionally two players, a revolver, and one bullet. The bullet is placed in a chamber of the gun's cylinder, the cylinder is spun, and one player aims the revolver at their head and pulls the trigger. if the gun does not go off the second player repeats the actions of the first. Depending on the players, the cylinder of the gun may or may not be spun again. Play continues until one player blows their brains out and ends the contest. It can involve up to 8 players, depending on the gun, and no one looses except the person who shot themselves with the one bullet. It is known as Russian roulette because of legends surrounding Russian soldiers between 1895 to 1930 when the standard issue firearm was the Nagant M1985 which had 7 chambers. Allegedly, Russian soldiers had suicidal tendancies and invented the game as a show of bravery, though in the autobiographies The Duel (1905) by Aleksandr Kuprin From Double Eagle to Red Flag (1921) by Pyotr Krasnov the game is never mentioned.

Everytime you play the Russian Roulette you stand a chance of 1/6 percent of getting shot, that's if each round the cylinder a.k.a the roulette ( because it's spun like one ) is spun with one bullet-occupied chamber.

i like em girls that's hard to get

today was quite fruitful, ponteng skool to lepak at home. O_O.. lepak with all muh books ..=.=!! really studied chemistry kau kau..having a very demanding teacher helps i guess, cz if it hadnt been for tht A**, i'd be sleeping th whole day n not even givin a damn bout chemistry.. results, out of 10 chaps that we've learn i manage to cover 6. woots~! eh, it aint easy to masuk so man y info n understanding em .. haha.. but its all worth it. guess im gonna skip de whole week then, one sub for each day..i'll so damn ready for that ezam.. woots~! haha.. this post goes out to alicia, who keeps bugging me to update. XD

thought of the day [rap to this]: 'F***' the world and what they think you should or ought to be. I'm just real to myself than
what u try to be. And when i take another step i dont always do so good. I do great,
I'm even tighter than your shoelace. do hate? this aint the capital of screw face..
Hah if you don't like me than screw you. I aint living in this place just to please you.
i'mma do me life, you can do you. we got more love just being us than you do.
uh~you're just a guy with nothing to fight for,faking this faking that you're nothing but a fake
like a can of milk from China, man you're just a waste.
so stop acting like you're great, or like you're desperate
so here's your boy AJ telling you to , chill out and let your life do you good

~peace out~

hey, not sure if this will help

1.
water is self-ionisation, therefore,
H2O(l) {in equilibirum} H+ (aq) + OH-(aq)

therefore, from the equilibrium law,
Kc = [H+][OH-] / [H2O]

since the degree of ionisation of water is very small right, the concentration, [ ], of water is negligible, therefore,
Kc[H2O]=[H+][OH-]=Kw

you already know that the conductivity measurements of [H+] and [OH-] at 25 Celcius is both
1.0x10^-7 mol/dm3, so therefore,

Kw=[H+][OH-] -----------> (i)
=(1.0x1o^-7) (1.0x10^-7)
=1.0x10^-14 mol^2/dm^6

pKw=-log Kw
=- log (1.0x10^-14 mol^2/ dm^6)
=14

therefore form (i) put -log base 10 to it
pKw=pH + pOH
=14

since the concentration of H+ ions in pure water at 298 K is 1.0x10^-7 mol/dm^-3, therefore

pH = -log (1.0x10^-7)
=7.0
(proven)

about the degree of dissociation, you must know Ostwald's dilutino law pretty well.. its not much anyway

take example: HA(aq) + H3O(l) { in equilibrium } H3O+ (aq) + A- (aq)

a strong acid will have a higher tendency to dissociate easier to form H3O+ ions as compared to a weaker acid, therefore the higher degree of dissociation , the stronger the acid..
but you must make sure that when you want to compare their degree of acid, the concentration of the acids that you are comparing are the SAME!!
why?..you need to read up on Ostwald's dilution law.. something about the degree of dissoiation being dependant on the concenrationof the acids.

the reason why the dissociation is not 100% or its a partial dissociation, is because it is more difficult to move a H+ ion from a negative ion: example

HSO4 - {in equilibrium} H+ + SO4 2-

the Ka is about 1.0x10^-2 mol /dm^3


basically just know that pKa=-log Ka....'p' is a way of expressing ( -log base 10 )
