Re: Naming [ENDORSED]
I believe that its not necessary in between names, but it is for in between numbers and names. Lavelle mentioned that the dashes in between names were meant to avoid confusion and promote better understanding of the different parts when teaching the material.

Re: First vs. Second Order
Can someone explain the difference between first, second, and zero order? I'm having trouble understanding exactly what the difference is- how does the concentration and reaction rate differ in each? What's the relationship between the two?

Re: Cation Vs. Anion [ENDORSED]
While a cation is an ion with a positive charge, an anion has a negative charge. Examples of cations include Sodium (Na+) and Lead (Pb2+). Examples of anions include Nitride (N3-) and Hydride (H-). Try thinking if it this way: cations have more protons than electrons, while anions have more election...

Re: Speed of light [ENDORSED]
I believe that the most important thing to remember is that c, the speed of light, is a constant value. Whenever c is used in a formula, always know that its value is 3.00x10^8 m/s. But, yes, 3.00x10^8 m/s is the speed of light in a vacuum.

Re: % Yield
So, using the information provided, you can definitely come up with a chemical equation for the rxn. This will allow you to better understand what is occurring within the reaction. The formula for % yield is:
Percent Yield= (Actual Yield/Theoretical Yield)x100%
Percent Yield= (Actual Yield/Theoretical Yield)x100%

Dear Joslyn, From the picture you uploaded, I believe the mistake was made due to the fact that you mistaken the percentages given for the grams of each element. For example, Xylitol is 39.43% Carbon. Since the total molar mass of Xylitol is 152.15 g/mol, then you would multiply the given percentage...
