Strong Acids and Bases
In writing a strong base and strong acid equation, would you use double arrows or a single arrow if the reaction goes to completion?

Re: Scale
Just remember that the pH of neutral water at 25 degrees C is 7. It's a good reference point for acids and bases!

Re: Equilibrium Constant
The pressure of a gas (partial pressure) is proportional to concentration. If you use the Ideal Gas Law, pv=nrt, you can see that you can manipulate the formula to give you concentration using pressure. Your set up should look like this: pv=nrt pv/rt= n p/rt=n/v Notice that n/v is just concentration...

Midterm 2007 review question [ENDORSED]
What is the maximum number of electrons in an atom that can have these quantum numbers?
n=5,ms=+1/2
The answer is 25 electrons but I do not understand how you get the answer.
Thanks!

Re: Octet Exception
Also, how would they fill their d orbital? Would it steal electrons from the 3s orbital or what? I'm confused.

Re: Electronegativity and Bond Types
It would help to know the values in order to categorize what kind of bond it is.
If the electronegativity value is greater than 2 it is an ionic bond. If the value is less than 1.5 than it is a covalent bond.
Hope this helps!

Re: QUIZ 1 [ENDORSED]
I highly suggest knowing common polyatomic ions and how to name compounds for the quiz. It will help with balancing equations and limiting reactant problems, fundamental topics I'm pretty sure will be on the quiz.
Hope this helps!

Re: Reaction Stochiometry L.3 [ENDORSED]
Hi! For a, I would start by converting the 1.5 mg Li3N into grams of Li3N. After converting to grams, I would use the molar mass of Li3N to convert the grams of Li3N to moles of Li3N. Then I would this amount to convert to moles of H2 by using the "conversion factor" (2mol H2/1mol Li3N) to...
