Re: Naming [ENDORSED]

If it were something like 1-bromooctane I believe you still can write it like that or you can write 1-bromo-octane. Same would apply to 1-bromoethane. I dont think vowels change the naming of the organic molecule

Re: Cyclo-

Also, I believe in lecture it was mentioned that if there is a double or triple bond in the structure, we start naming from the carbon on the double or triple bond then count the substituents

Re: Naming Organic Compounds

This actually doesn't work, if we read the textbook it specifically brings up that thought. On page 8 it says "2,7,8-trimethyldecane is the correct name even though the sum of the numbers (2+7+8=17) is higher than the sum, 16, obtained from the incorrect name 3,4,9-trimethyldecane." So we ...

Re: Slow Reaction

When it comes to the slow step reaction is the reaction that is reversible also the slow step reaction? So if it states that the reaction is reversible k and k(prime) would be included in the slow step reaction as well?

Re: Midterm Winter 2017

Will values like specific heat of different compounds/ elements be given when they're necessary or should I memorize a few basic ones like water, ice and steam? It was said we would be given equations and values that we would need for the test, so the specific heat, the value of R and F etc should ...

Re: Calculating K for reaction using half reactions [ENDORSED]

In the explanation for the question it says that we should expect E to be negative because the K to be very small, and in order of that to happen the the value of E(naught) must be negative

Re: Salt Bridge

The metal acts as the conductor so that the electrons can move, so I wouldn't believe the metal ions would be the one that is being transferred as the electrons are moving from areas of high concentration to areas of low concentration causing the charge of the two substances to increase or decrease....

Re: Equilibrium Constants

Because the equation is that delta G*=-RTlnK and we know K= [P]/[R] So if the K=1 delta G would equal -RTln1 and ln1=0 If K<1 (when R is greater than P) then it would be ln(.5 for example) which is a negative number. The natural log of all numbers less than 1 and greater than 0 is negative. Which wo...

Re: Unit Question [ENDORSED]

The equation for work is work=P*deltaV and the units that come from that is
P*deltaV= kg*m^-1*s^-2(m^3)= kg*m^2*s^-2 which equates to Joules
So if im not mistaken, the units for work should come out in Joules

Re: heat q(sys)+ q(surr) =0

I believe it would still apply, because the heat that is being released into the aqueous system will still be moved into the surrounding of it. So we define our system as the closed system with an aqueous solution that you described and when the heat energy is released it is being released into the ...
