• ### How do you solve this titration problem?

What is the hydrogen ion concentration (M) of a solution prepared by mixing 50.00mL of 0.10M HCN with 50.00mL of 0.050M NaCN? Assume that the volumes are additive. Ka = 4.9 x 10-10 for HCN.

• ### How do you solve for x with the given equation?

(6.4)^1/2 = x (2-x)^-1 I drew a blank on this problem and I need a little help. I resorted to my calculator and graphed the equation. I found the zero of the equation, and found it out to be ~ 1.43. I was able to bring the equation down to: x + x(6.4^(1/2)) - 2(6.4^(1/2)) I cannot remember how to factor the square root problems. It's... show more

• ### Spam filter does not seem to be working on Verizon e-mail account...?

I am constantly sorting out literally 100s of junk emails a week. It's the same ones too, even though I marked those emails as spam. A few of the spam junk mail I signed-up for them not to send me crap, but they're still appearing after weeks/months. I'm wondering if Verizon is inadequate in the spam filtering business.

A few of the spam junk mail I signed-up for them not to send me crap, but they're still appearing after weeks/months. I'm wondering if Verizon is inadequate in the spam filtering business. Anyone else have this problem (or with any other provider)? I know to select all and delete the junk at once, but it is truly ridiculous that I have to sort through so many just to find the emails I need.

• ### What is the song from the latest Brüno commercial?

In the commercial, there were only das in it. I tried to figure out what the notes are and here is what I got - A E A E D C C C E C E C D C A A A. Each note is the same beat, except for the D which is half of the regular beat. A is lower than the CDE keys in this song. If you think you know this song, it would be greatly appreciated if you could... show more

If you think you know this song, it would be greatly appreciated if you could answer this! It is a techno song with a male voice with chants in it. It is not Perfect Exceeder, Numa Numa, the song from Scooter, or the classical song. I cannot find the commercial on the internet sadly.
