Re: Amphiprotic

Amphiprotic= a substance that can both accept and donate a proton (has characteristics of both an acid and a base)

amphiprotic vs. amphoteric:
-a substance is amphoteric when its reaction acts as an acid and as a base
-amphiprotic only applies to protic compounds

Re: Resonance

adding to that, resonance means that some lewis structures have multiple bonds in different equivalent locations

(e.g. from lecture NO3^-)

Re: Reading the textbook [ENDORSED]

going to be honest, I only use the textbook to get homework/practice problems. to me, too much reading makes it confusing, so I mainly utilize my lecture notes and do lots of practice.

Re: Drawing Lewis Structures

does anyone have any tips for making sure that you have enough valence electrons drawn when accounting for double bonds?

Re: delocalized electrons

by definition: a delocalized electron is an electron that is not associated with a single atom/covalent bond

however, I'm also not quite sure why the lewis structure doesn't capture this effect???

Re: Video Module Assessment

step 1= convert nm to m 1nm= 10^9m so... 194nm = 1.94 x 10^-7m step 2= use speed of light formula: c=(wavelength)(frequency) 3.10 x 10^8= (1.94 x 10^-7m)(frequency) frequency= 1.546 x 10^15 Now you can plug the frequency into the formula for kinetic energy: E=hv E= (6.626 x 10^-34)(1.546 x 10^15)= 1...

Re: Numbers to memorize [ENDORSED]

All I would say, is that for test 1 don't worry about having constants or unit conversions memorized (as they will be given), but for future reference (e.g. the midterm and final) to know and understand them.

I know for a fact that all constants and equations are given. But as for the molecular vs empirical formula section, just in case I would practice finding them when it is not given!

Re: 5 Homework Problems Due

I agree with what most people have posted... i think its best that you try and practice problems for a variety of sections just as preparation for exams. In Dr. Lavelle's syllabus he even notes that 1 out of 8 homework questions are used in exams, so there's a possibility that you know some answers ...
