Oh right! Thanks for letting me know- I'll fix them also!

You use bi and tri when the compound already has a di/tri type naming in it. For example, ethylenediamine already has di because it is referring to its two amine compounds; in this case, you would use bis if you had two of these. It would be called bisethylenediamine.

Someone else had this issue and posted it here as well. If you do the molecular orbital diagram Br2 2+ is paramagnetic- it has unpaired electrons in the 3pi*x and 3pi*y. However, Br2 is diamagnetic as shown in this: http://chemwiki.ucdavis.edu/@api/deki/files/10233/solution_to_problem_5.jpg?size=bes...

I made a quick set of flashcards to study VSEPR geometries. It has the name and degrees on one side and the description with a picture on the other side. For example it says 2 bonds and 0 lone pairs, AX2. Here is the link if you want to study it: http://quizlet.com/62137138/flashcards"onclick="windo...

Which final are you talking about? I drew a molecular orbital diagram for (Br2)2+ and agree with you; it is paramagnetic with unpaired electrons in its 3pi*x orbital and 3pi*y. If the question was asking about just Br2 then it would be diamagnetic because the two electrons we took away to form 2+ wo...

The Henderson-Hasselbalch equation is used for problems involving pH. ICE tables are used when you change concentrations or have different initial and ending equilibriums. The problems usually involve weak acids/bases and salts. Another key term to look for is "buffers" because it will pro...

Autoprotolysis is taken into account in two different ways for strong acids and weak acids. For strong acids and strong bases, you only have to take autoprotolysis in to account when the concentration of the strong acid or base is less than 10^-6 mol/L. The process is similar for weak acids. You hav...

If you want a graphical representation of what Anuk is saying, here you go. These graphs are pretty general for graphing concentration against time for any reaction. Note that for products, the initial concentration starts at 0 where as for reactants, the initial concentration is higher. They both p...

I agree with Helen. Double bonds do not indicate expanded octets; they are often used in order to obey the octet rule. All lewis structures should obey the octet rule except for a few special cases. These include: 1. Species with an odd number of electrons, otherwise known as free radicals. An examp...

Do you have 11 protons?
Cause you sodium fine
