well the pH was 3 yeah.... so that means that the [H+]= 10^-3.....(Common rule [H+]=10^-pH) if the acid was a strong acid for example .1 M HCL. the ionisation will be HCL--> H+ + Cl- and useing your mole ratios... the concentration of [H+]= .1 do ([hydrogen ions] in the weak...

write the equation C2H6O+ 3O2 -->3H2O+ 2CO2 in on tone of co2, there is 22727.27273 moles. divide by 2 to get the moles of ethanol (mole ration from balanced equation) and moles ethanol = 11363.63636. times this by the delta H given in the equation... 11363.63636 X 1367 =15.53x10^6...

only 4.. urs?

nah recess for me :D got double maths next yay!

lol hey sup.... ur on at school aswell

2008 the question is as follows: a reatcion between a particular hydrocarbon and bromine produces the following. CH3CHBrCHBrCH3 which of the following hydrocarbons was reacted with bromnie to produce this product? (a) 1-propene (b) Butane (c) 2-butene (d) propane i think that both B...

is an subsitution and addition both reactions... cause and independent paper DON'T say so...

still aiming for 99.20 though

screwed up english lol

EPIC lol

sup niggar!

(1+cos(x) +isin(x))^{n} = (2^{n}cos\frac{x}{2}(cos\frac{nx}{2}+isin\frac{nx} {2})). you need to put it between [tex] and [:/tex]... remove the :

Spend like two hours looking at this site: SparkNotes: Frankenstein and read the plot overview and then read the symbols and stuff... go to this site for BR: BRmovie.com: Blade Runner Analysis. just spend a few hours reading these sites and you should get what is going on... compare a few...

i have a study guide. you should get one. seriously. like what don't u know about the texts?

buy a study guide

maybe trying making three different commutators and put them together.... you will need six brushes... GL

lol i was joking about the bunsen

do you need to use a bunsen?? cause i can lend you mine...

don't we need to find the excess moles of H2SO4 first?

evaporate the water from the solution... so ur left with sugar and KCl... then heat up the powder to 200 degrees so that teh sugar melts and the KCL will remain solid.... don't think you will ever need to do this and i don't even think that the solution i gave is correct lol
