If the Silver Surfer and Iron Man team up, they’d be alloys.
Why was the mole of oxygen molecules excited when he walked out of the singles bar?
He got Avogadro's number!

Lone Pairs in expanded Octet?
I'm a little confused on how I am supposed to know how many lone pairs and atom will have when drawing expanded octet Lewis Structures. For example on question 3.63, Xe has 2 bound pairs and 3 lone pairs, but on 3.65, Xe can have 4 bound pairs and 2 lone pairs, I am just kind of confused on how to t...

Re: 2.13 Homework Question [ENDORSED]
I think this question is just kind of deceiving because of how simple the answer is, the x,y,z labels on the p are specifically for the purpose of being able to refer to which axes the lobe lies on, therefore the orientation is simply the direction of which axis (x-axis, y-axis, or z-axis) each lobe...

Re: Quiz 1 Prep Fall 2015
5.43g Al x (1 mole Al/26.982g Al) x (2 mole AlCl3/2 mole Al) x (133.341g AlCl3/1 mole AlCl3)= 26.8g AlCl3 7.8g HCl x (1 mole HCl/36.461g HCl) x (2 mole AlCl3/6 mole HCl) x (133.341g AlCl3/1 mole AlCl3)= 9.51g AlCl3 Since the final mass values are different depending on which reagent we base our calc...

Q. 1.11 Lower energy levels for spectral each spectral series? [ENDORSED]
The question for 1.11 is " In the spectrum of atomic hydrogen, several lines are generally classified together as belonging to a series... What is common to the lines within a series that makes grouping them together logical?" I understand the answer to the problem that is in the solutions...

Re: Problem 10 on Limiting Reactant [ENDORSED]
As the previous poster said, double check that your equation is balanced because I got that the balanced equation is C6H9Cl3 + 3 AgNO3 --> 3AgCl + C6H9(NO3)3 Then what I did next was the following: 0.750g C6H9Cl3 x 1mole/187.5g= 0.004 moles x (1mol C6H9Cl3/ 3 mole AgCl) x (143.32g AgCl/ 1 mole AgCl)...
