@Dennis I am aware of that, just needed a quick answer and no one would reply in the science chats
Dec 9, 2016 02:44
@EᴀsᴛᴇʀʟʏIʀᴋ Ah, alright awesome thanks :P
Dec 9, 2016 02:44
@EᴀsᴛᴇʀʟʏIʀᴋ Me too...

@EᴀsᴛᴇʀʟʏIʀᴋ I tried to look up the reason on the internet but could not find it, and so made a hypothesis based on periodic trends, electron configuration and crystal field theory.. lol
Dec 9, 2016 02:41
@EᴀsᴛᴇʀʟʏIʀᴋ For real?

Is it simply because the atomic radius increases, the d-orbitals are closer to the ligands in a complex and thus there is a greater electron repulsion in the octahedral electrostatic field, meaning that the electrons in the d-orbitals will be displaced by a greater amount resulting the crystal field splitting energy to be greater?
Dec 9, 2016 02:38
I am not sure if this is the right place to ask, but people in the h-bar chat didn't reply. Just a question regarding crystal field theory: why does the crystal field splitting energy increase as we go down a group with the same oxidation state?

Since the atomic radius increases down a group, doesn't that mean that the d orbitals are going to be farther away from the center, does that cause a greater electronic repulsion with respect to the ligands in the complex, and is that what causes an increase in the crystal field splitting energy???

Hello, I have a question regarding crystal field theory, why does the crystal field splitting energy increase down a group with the same oxidation state in a complex?

Any idea how to approach this: math.stackexchange.com/questions/2037297/…

Nov 27, 2016 23:38
how can we simplify $\frac{y_1}{y_2}$, where $y_1=\frac{3199}{12689}x+7.43$, and $y_2=\frac{2017}{8000}x+\frac{5943}{800}?
Nov 27, 2016 23:18
@Semiclassical I am calculating that, one sec
Nov 27, 2016 23:17
@Semiclassical When the question says "ratio," I am assuming it wants an actual numerical value rather than a value that consists of variables?
Nov 27, 2016 23:15
@Semiclassical Ah ok, I'll just pick the mother function then
Nov 27, 2016 23:13
@Semiclassical $x^2-y^2=1$, $\frac{x^2}{2}-\frac{y^2}{2}=1$, etc. These are different
Nov 27, 2016 23:12
@Semiclassical Should I look at the ratio of AX:AB in different hyperbolic functions, and see if the ratio is very similar
Nov 27, 2016 23:10
Ah alright, should I just pick specific hyperbolic functions and compare the ratios?
Nov 27, 2016 23:09
@Semiclassical Can you explain how we can us affine transformations to figure out the ratio of AX:AB in the hyperbola problem?
Nov 27, 2016 21:17
and that will look extremely messed up, as in rlly rlly jumbled up variables in each equation
Nov 27, 2016 21:17
If we took a general case, then instead of numbers, it will be variables
Nov 27, 2016 21:16
I'll just go ahead with this proof :P
Nov 27, 2016 21:15
Inductive right?
Nov 27, 2016 21:15
What kind of reasoning was that called? Deductive or inductive?
Nov 27, 2016 21:15
After demonstrating a specific case, I'd go about a general case
Nov 27, 2016 21:14
So I should just write that down in words?
Nov 27, 2016 21:14
the result that no matter what the case is, ZC will always intersect AB at X correct?
Nov 27, 2016 21:13
then it will give you the same result
Nov 27, 2016 21:13
if the proportion is the same
Nov 27, 2016 21:13
But it doesn't matter if you shift it, twist it, stretch it
Nov 27, 2016 21:13
What do you mean?
Nov 27, 2016 21:12
No I just chose points
Nov 27, 2016 21:12
@Semiclassical Is my proof good enough? imgur.com/a/vKKzG
Nov 27, 2016 20:29
@Semiclassical yeah b is just 0 lol
Nov 27, 2016 20:25
and then calculate b :P
Nov 27, 2016 20:25
using the two points
Nov 27, 2016 20:25
just find the slope
Nov 27, 2016 20:25
oh
Nov 27, 2016 20:24
how to find the equation of the line that passes through an intersection and the origin? xD
Nov 27, 2016 19:19
I don't quite get how showing that the hyperbola remains unchanged proves that line ZC passes through X :p @Semiclassical
Nov 27, 2016 19:18
The calculus approach makes more sense to me for some reason
Nov 27, 2016 19:12
one sec
Nov 27, 2016 19:10
I am studying math alone, not in a course
Nov 27, 2016 19:09
Yeah, but how can I do any proof... like I literally have no idea...
Nov 27, 2016 19:09
but if follows the same condition or scenario
Nov 27, 2016 19:09
I just picked random points btw
Nov 27, 2016 19:08
Nov 27, 2016 19:03
I am drawing one though
Nov 27, 2016 19:03
not yet @Semiclassical
Nov 27, 2016 19:02
ah ok
