<p>@mathpop: I believe mass spectroscopy for isotopes and photoelectron?</p>
<p>^Photoelectron for the binding energies?</p>
<p>what constants should we have memorized by tomo? specific heat of water? Faraday’s Constant? any other ones</p>
<p>Not to be a pessimist, but when they reworked Bio, it was 5% 5s lol. It’s not looking too good :p.</p>
<p>formal charge or octet rule?
which takes precedence</p>
<p>@PersianPwr the 1st container has 10 moles of agno3. The 2nd container has 5 moles mgcl2. The 3rd container has 5 mole mgno3 but its molarity is lower (1/2) because its a larger container, and the mol to Liter ratio is smaller. PM me if you still don’t get it.</p>
<p>No formal charge? Teacher said there wasn’t but its not too bad. Octet rule, yes, I think.</p>
<p>I agree with @NIGHTLOCK on the freaking last frq lol. does anyone know a good source where we can learn that concept? like how bonds affect the color of a solution and everything???</p>
<p>And memorizing molecular geometry crap.</p>
<p>Octet Rule</p>
<p>@KbbGrizzly did you read the explanation?? It makes sense then.</p>
<p>what about UV spectroscopy and IR spectrocopy?</p>
<p>on the bright side the last frq was only 4 points and it was easy to get 1-2 of them</p>
<p>i got 25% on mc…
totally screwed</p>
<p>maybe you weren’t trying as hard since it didn’t matter</p>
<p>I doubt it. Wavelengths and freq are fair game though, but I haven’t seen any questions about them.</p>
<p>do we have to memorize the order of the em spectrum? </p>
<p>wait @meaa7130 I missed a lot cause I was doing my practice exam on my barrons. What page is the explanation on??</p>
<p>Teacher’s buying us breakfast tomorrow!@! Can’t let him down #xtraburden.</p>
<p>@meaa7130: NO WAY, lol.</p>
