Chemically, methoxsalen belongs to a class of organic natural molecules known as furanocoumarins.

Plus 5 molecules, I'll just think of it in terms of individual molecules for now, plus 5 molecules of molecular oxygen.

We have 3 separate molecules, 1 here and 2 molecules of oxygen.

Chemical reactions can result in the formation or dissociation of molecules, that is, molecules breaking apart to form two or more smaller molecules, or rearrangement of atoms within or across molecules.

So antenna molecules are other types of chlorophyil, and actually other types of molecules.

Many larger, complex molecules are just a bunch of smaller molecules bonded together

So if I multiply everything by two, I end up with two molecules of ethane plus seven molecules of diatomic oxygen, seven O2's, yielding two molecules of carbon dioxide oh, sorry, I'm multiplying everything by two, so four molecules of carbon dioxide, plus six molecules of water.

Instead, think of water molecules.

And right over here, these are molecules of sweat, or it's really just molecules of water.

So there's a bunch of hydrogen molecules around, and some of these iodine gas molecules around.

Organic chemists make molecules, very complicated molecules, by chopping up a big molecule into small molecules and reverse engineering.

Organic chemists make molecules, very complicated molecules, by chopping up a big molecule into small molecules and reverse engineering.

Diatomic molecules are molecules composed of only two atoms, of either the same or different chemical elements.

Class address, class background, class characters.

I have 2 molecules of water.

Vinegar is an example of a solution where the molecules of acetic acid are blended with molecules of water.

And while I was sneakily reading this article under my desk in my biology class, we were supposed to be paying attention to these other kind of cool molecules, called antibodies.

Right now I'm thinking of individual molecules.

I'd never really thought of molecules before.

yields one of these molecules, SO4 3.

Oil is a stew of hydrocarbon molecules.

Yep, three water molecules.

The pathway requires 18 molecules of ATP for the synthesis of one molecule of glucose, whereas the pathway requires 30 molecules of ATP.

It's just made up of a whole bunch of the molecules of the gas itself, and I'll draw each of the molecules with a little dot it's just going to have a bunch of molecules in it.

The process of ionization changes atoms and molecules.

The same is true of our hypothetical molecules.

The same can be said of our molecules.

Let me draw one of this guys molecules

Class of printers

Name of class

So these are water molecules

Molecules are competing for stuff.

And they really help molecules,

Although the size of most molecules would fit into the above outline, individual molecules are usually not referred to as nanoparticles.

And I ended up with four aluminums plus three oxygen molecules, or six oxygen atoms, yields two molecules of aluminum oxide.

So we made molecules that look kind of like the real molecules which you saw but they're a little bit different.

However, the following properties are typical of such molecules.

All molecules are made up of atoms bonded together.

Astrophysics In astrophysics, photodissociation is one of the major processes through which molecules are broken down (but new molecules are being formed).

Where formula_1 is the internal energy of formation of the reactant molecules that can be calculated from the bond energies of the various chemical bonds of the molecules under consideration and formula_2 is the internal energy of formation of the product molecules.

A chap got out of first class... with a third class ticket.

Top of the class!

So these molecules are called channelrhodopsins.

Now molecules are really, really tiny.

And those red molecules are hemoglobin.
