How did you go from:
[HN]= 10^-3.26 to
5.495 times 10^-4
Where did you get the 5.495?

If one of the reactants is a solid, (i.e. the other is a gas), then would the partial pressure of the solid be 1?

a. Call the niacin HN Definition of Ka Ka = [H+]*[N-] / [HN] Let the [H+] = X. Because [H+] = [N-] , then [H+]*[N-] can be written: X² Because the dissociation of HN↔ H+ + N- is very small compared to the concentration of HN, we can ignore this and call [HN] = 0.02M Substituting: Ka = X²/0.02 From p...

You could add when you would add "ion" to the end of the name.

"Dien" is a short-hand way of writing the name for the ligand diethylenetriamine (which has the same name under the new IUPAC conventions).
The formula is:
NH2CH2CH2NHCH2CH2NH2.
You can also find this on page 101 in the Course Reader.

At the end of the semester, a chemistry teacher asked her students what was the most important thing that they learned in lab. A student promptly raised his hand and said, "Never lick the spoon." Q: Why does hamburger yield lower energy than steak? A: Because it's in the ground state. Heis...

Not a typo. We know that Pd has 46 electrons by looking at the periodic table, and we know that "s" orbitals can have a maximum of 2 electrons, "p" can have 6, "d" can have 10, and "f" can have 14. So the full electron configuration for Palladium would start w...

(From homework question 1.29)
What is the minimum uncertainty in speed of an electron in a Pb atom which has diameter equal to 350 pm?

My question:
What would you do differently if it asked for "maximum" uncertainty? Or would that not need to be calculated?
Thank you.
