Any clues? E.g. is it on the net or...

Where do you guys get all this stuff from?

Ep is based on work. You should've used that Ep thing. You may still have gotten the right answer, who knows

Limiting sum Use a-d, a and a+d Then use 1/a, 1/(a+d) , 2/(a+d) - 1/a Show LHS =RHS

Re: Cssa Yea I did it. Decent paper Depends on how the trial affects your ranking

Lol, what a last reply to "woga1" (Y)

Tension OB? Isn't it AB. Haven't done circular motion yet so idk

There are an infinite amount of possibilities, yes. Hence 1/infinity. Using limits, this is zero. However, there is a chance of selecting that number. Hence paradox

Shit, -n... Then yea it would be A

^ obvious lie is obvious

Shouldn't it be B

Prove that Einstein's theory on special relativity is wrong

Re: CSSA Chemistry 2011 Yea...I saw people doing it in class that way, but found it quite illogical. Was so tempted to go with the equal equal

Re: CSSA Chemistry 2011 it should be right. I put carbon dioxide

Re: CSSA Chemistry 2011 From what I've gathered... 0.25 mol/L of sulfuric 0.5 mol/L of HCL Sulfuric acid will fully disassociate itself to hydronium + HS04-. But HSO4- does not fully ionise. Hence you couldn't really multiply 0.25 by 2. hence HCL will have more hydronium ions and hence have...

HOLY SHIT spiralflex wtf!

Depends on what you mean. If they've recorded the heat as only 70% of the heat of combustion, then divide it by 0.7 to get all the heat.

Make a rectangle, then find the area bounded by curve and y axis You tried that? arj1 confirmed it works oh wait, it's hermes1 now?

Ignore first part. I misinterpreted the question

No, if It ionises by 10% you add the hydronium ions to form one big concentration. I like that question, it's more realistic Oh wait a minute, you are correct. I was thinking of H3PO4--> H+ +H2PO4-. As you keep going it ionises less,etc[not sure if phosphoric acid ionises like that
