Hello everyone
 
if you have questions before I get here, plese post below......
 
It is 9:11....I am a bit late.  If you are checking in, please post questions.  
Soo can you explain 5.2 for a second
Just a minute
 
if the temperature rises, then energy must be released....so exothermic.  The sign would be negative.
And we just know that from common sense?  yes....
How about C on 5.3
change 10 grams of FeBr2 to moles.  you know from the equation that 249.9 kj of energy are release when one mole of FeBr2 is formed.  so multiply the number of moles in 10 grams by 249.9 kj/mole.
So it is the same way for 5.33 and the rest?
yes.  on d, you would use the kj/mole relationship and change kj to moles, then grams.
Ok those were my biggest questions, is there anything else you think I should remember for the quiz tommorow?
 
I took the questions almost directly from the homework, so if you understand the sheet, you should be fine.   Be sure that you don't just "kind of understand."
Well so far through the worksheet, I feel like it mostly just depends on memorizing that formula, would that be safe to say? because I understand that concept pretty well
 
Be sure that you understand the ∆G equation, and how to solve for ∆S or T if given G and H.  also be sure that you understand that more disorder means more entropy.
Yeah that is what I meant by formula, (delta G)option j gives you a delta on mac.∆
I'm trying to figure out if it also does that for samsung, I'll figure it out eventually.  OK.   If you are OK I am going to sign off.   It looks like a light turnout
 
 
Yeah I am pretty good, I'm definantly gonna study a bit more though, I appreciate the extra help, sorry no one else got online, I think we forgot to post it on the Facebook page
