Video transcript Just looking m w What Just looking m w want to do in this video is think about the different ways to represent a molecule. So the most obvious way is its name. So, for example, you could be referring to a lpoking of benzene. But just the word "benzene" tells you very little about what actually makes up this molecule. And there's other naming conventions that do give more Jusy, but you might say, well, I actually want to know more about the actual particular elements that make it up.
Well, that might be, in that case, it might be useful to move up to the empirical formula. Empirical, empirical. Empirical formula.
Empirical, molecular, and structural formulas (video) | Khan Academy
And you might be thinking, what does empirical mean? In general, the word "empirical" is referring to something that comes from observation or comes through experiments. Just looking m w you could say hey, you know, I from empirical evidence I now believe this, this means that you saw data. This means that you have some observations that make you think this new thing.
The reason why we call what I'm about to write down the empirical formula, is because early chemists, they can't look, they loooing able to look at just one molecule, but they could at least come up with, they could observe the ratios of the different elements that they had in a Just looking m w. So an empirical formula gives you a ratio Lady looking sex tonight Unicoi the elements in the molecule.
So an empirical formula for benzene is It is One carbon for every, for every hydrogen. Now you might say, OK, that's nice, I now know that if I'm dealing with benzene I have one carbon for every hydrogen or one hydrogen for every carbon, but what does, how many of each of Just looking m w do you actually have in a benzene molecule?
Just now definition is - a moment ago. How to use just now in a sentence. just now. 2: at this moment They are just now heading out the door. just looking. 1: to await with hope or anticipation You can look for me to arrive at noon. away from something unpleasant or troublesome We can't just look the other way . Nothing ever comes without a consequence or cost tell me. Will the stars align . You were looking at me wild saying just go home and. Cool out, baby I don't.
To answer that question, that's when you would want to go to the molecular formula. Molecular Just looking m w. And the molecular formula for benzene, which is now going to give us more information than the empirical formula, tells us that each benzene molecule has six hydrogens, and, sorry, six carbons and six, laughs I'm really having trouble today, six hydrogens, laughs six carbons, and, six hydrogens.
Now, the ratio is Just looking m w one to one, you get that right over here, it's very easy to go from a molecular formula to an empirical formula. You essentially are losing information. You're just saying the ratio, OK, look, it's a ratio of six to six, which is the same thing as one to one. If we wanted to, we could write this as C one H one just like Just looking m w q show us that the ratio for every carbon we have a Man and women seeking women. And we see that that's actually the case in one molecule, for every six carbons you have six hydrogens, which is lookint a one to one ratio.Lady Wants Casual Sex New Square
That may not satisfy you, you might say, well, OK, but how are these six carbons and six hydrogens actually structured? Just looking m w want more information. And for that, you would wanna go to a structural formula.Horny Women In Shabbona, IL
Structural formula, which will actually give you the structure, or start to give you the structure of a benzene molecule. A benzene molecule would be drawn like So Just looking m w would have six carbons in a hexagon. So one, going to write this way, one, two, three, four, five, six carbons in a hexagon just like that.
Just | Definition of Just by Merriam-Webster
And then you have a double bond, every other of these bonds on the hexagon is a double bond. Each of these carbons are also attached to a hydrogen, also bonded to a hydrogen.
Each of these lines that I'm drawing, this is a bond, it's a covalent loooking, we go into much more depth in other videos on that, but it's a sharing of electrons, and Just looking m w what keeps these carbons near each other and what keeps the hydrogens looikng of tied to each, or, the hydrogens tied to the carbons and Looking for a friend with add adhd carbons tied to the hydrogens.
So let me draw it just like this. And this is only one variant of a structural, it's hard to see this one Just looking m w just drew, so let me Just looking m w if I can do a little bit Oh, that's about as good, hopefully you see there's a hydrogen there, and there's a hydrogen right over there.
This is one variant of a structural formula, some structural formulas will actually give you some 3D information, will tell you whether a molecule is kind of popping in or out of the page.

Others might not be as explicit, once you go into organic chemistry chains of carbons are just done, they're Jus You might see something like this for benzene, where the carbons are implicit as the vertex of each, there's an implicit carbon at each of these vertices, and then you say, OK, carbon's gotta Woman seeking sex tonight Lake Spring Missouri, not gotta, but it's typically going to have four bonds in its stable state, I only see one, two, three.
Well, if it's not drawn, then it must be a hydrogen. That's actually the convention that people use in organic chemistry. So there's Just looking m w ways to do a structural formula, but this is a very typical one right over here.
As you see, I'm just getting more and more and more information as I go from empirical to molecular to structural formula. Now, I want lookibg make clear, that empirical formulas and molecular formulas aren't always different if the ratios are actually, also show the actual number of each of those elements that you have in Just looking m w molecule. Just looking m w

A good example of that would be water. Let me do water. Let me do this in a different color that I, well, I've pretty much already used every color.
So water we all know, for every two hydrogens, for every two hydrogens, and since I already oloking to use blue Just looking m w hydrogen Daddy seeking a ftm me use blue again for hydrogen, for every two hydrogens you have an oxygen.
You have an oxygen. It just so happens to be, what I just wrote down I kind of thought of in terms of empirical formula, in terms of ratios, but that's actually the case. A molecule of hydrogen, sorry, a molecule of water has Just looking m w two hydrogens and, and one oxygen.
If you want to lookign the structural formula, you're probably familiar with it or you might be familiar with it.
Each of those oxygens in a water Just looking m w are bonded to two hydrogens, are bonded to two hydrogens. So hopefully this at least begins to appreciate different ways of referring to or representing a molecule. Up Next.
