Re: Functional Groups Naming (Priority?)

Hello
Yes, when naming we give priority to the functional groups. Dr. Lavelle said that we will not be doing more than 1 functional group so you don't have to worry about that!

Re: Naming

We can't name it 5-ethnyl-3-methyl-heptance because when numbering the carbons in the longest hydrocarbon chain, the carbons have the same numbers going from right to left and left to right. In this case we look at the names of the substituent and whichever comes first alphabetically, that is the on...

HW 14.55

A 1.0M NiSO4(aq) solution was electrolyzed by using inert electrodes. Write (a) the cathode reaction; (b) the anode reaction. (c) With no over potential or passivity at the electrodes, what is the minimum potential that must be supplied to the cell for the onset of electrolysis? Can someone help me ...

Re: Standard Potential and Spontaneous Reactions

Yes, if the standard E cell is positive then the reaction is spontaneous and if it is negative it is non-spontaneous

9.81

Which is the thermodynamically more stable iron oxide in air, Fe3O4(s) or Fe2O3(s)? Justify your selection.
In the solution, they wrote the chemical equation 4Fe3O4(s)+O2(g)-> 6Fe2O3(s). How would I know based on this problem that I would have to do this?

Re: Quiz 2 Summer Workbook problem [ENDORSED]

Well what I did was that the initial concentration of BrCl is given which would be 2.80x10^-5 M. I ignored the 8.12% at first because it can get confusing so I just then I created the ICE box. 2BrCl Br2 Cl2 I (M) 2.80x10^-5 0 0 C (M) -2X +X +X E (M) (2.80x10^-5)-2X X X After I saw that they technica...

Re: Bond Order

I think it is the larger the BO, the shorter the bond length meaning the bond is strong. So, if the BO is small the bond length is big and therefore the bond is weak.

Converting between Kp and Kc

In lecture, Professor Lavelle told us to use PV=nRT to convert between Kp and Kc. In the book the formula: Kp=(Kc)(T/12.03K)^(∆nr) is used. Which way is better to use?

Re: G5 approach to question

To the person who said they did not understand the way that the solution manual approached the question, they did it based on the formula Molarity(c)= mol(n)/ volume(V), not the other one. I did it this way and what I did was first find the molarity of Na2CO3, which I did by converting 2.111 g to mo...
