When to disregard -x in equilibrium formula?
Under what circumstances can we disregard the subtracted "x" from the reactants in the equilibrium formula?

Fall 2014 Final Exam Q3C
Hi everyone, On page 245 of the chem course reader, question Q3C asks about the ground-state valence electron configuration of Cl2+. I understand how to find the valence electron configuration, the magnetic properties, and bond order, but how exactly do I know whether Cl+2 is more or less stable tha...

Amphiprotic substances
Are there any other key amphiprotic substances other than water that we should know? Also, are all amphiprotic substances amphoteric? I'm a bit confused on the relationship between amphoteric and amphiprotic.

Re: Formula for coordination complex?
From what I understand, in the coordination complex you name the ligands first (alphabetized), and then you name the metal atom or ion.

Re: Covalent and Ionic Character
Yes that's true because fluorine's electronegativity is greater than chlorine's.

Homework chapter 3 #99
Can someone please help me with this problem? It reads: "In 1999, Karl Christe synthesized and characterized a salt that contained the N5+ cation, in which the five N atoms are connected in a long chain. This cation is the first all-nitrogen species to be isolated in more than 100 years. Draw t...

Re: Octet Exception
For period 2 elements to obey the octet rule, they need to complete their valence shell with eight electrons. Li and Be follow the octet rule when they ionize, but they are exceptions to the octet rule when they form covalent compounds. This is because they don't have enough valence electrons to for...

Re: 1.21 Homework Question
The photoelectric effect supports electromagnetic radiation as being particlelike because of the nature of how electrons are removed. Electrons are removed from the metal as photons, which are particles like you said, collide with them. A collision between the two particles is required in order to e...

Re: Minor Rounding Detail Question
I believe in lecture it was said that the value for the speed of light will be given in the problem whenever it is on quizzes/tests, so I wouldn't worry about memorizing one or the other. Still, I agree that on homework, etc. rounding up to 3.00*10^8 is probably fine.
