A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, a liquid is one of the four fundamental states of matter (the others being solid, gas and plasma). A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Water is, by far, the most common liquid on Earth. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena.

A liquid is a state of matter in which a substance changes its shape easily and takes the form of its container, and in which the substance retains a constant volume independent of pressure. As a result of this, a liquid does not maintain a definite shape, and its volume is variable. The characteristic properties of a liquid are surface tension, viscosity, and capillarity. The liquid state has a definite volume, but it also has a definite surface. The volume is uniform throughout the whole of the liquid. Solids have a fixed shape and a definite volume, but they do not have a definite surface. The volume of a solid does not vary, but the volume of a liquid may vary.

for this problem. We're going to talk about eso to hydration as it fits into the Lewis acid based theory. Check and see if my speeds up. So I am going Teoh right out the equation, and then I'm going to write the structural formulas eso to I'm gonna leave states out this for the moment. And since it's hydration going with water, I guess I can put him on here. And my product for this And this is, um, reversible reaction will be h two and so three. Okay. And this is gonna be a quick Okay, so this is my reaction. So let's look at our structural formulas s I'm going to write as and this is the important pair of electrons right there. Water is h. And over here, I've got my s in the middle. Make sure I've got room to get this on here, and I'm gonna have I think I'm gonna have pair on unshared pair of electrons and Oh, and oh, and an O This one is gonna have to with the hydrogen. This gonna have to with a hydrogen. And this one can have 123456 There we go. So that looks good. So now we've got these. And let's switch colors here to gold. So what's gonna happen? We can think of a pair the A train here. Let's take this age. We can think of her h as moving over to this spot. So that's our aged. Basically moved over to this spot right here, and it and, um, brought that over here so we don't have a double bond there anymore. This accepted an electron pair. This is electron pair, except er. Now let's see what else happened here. Um, the other hydrogen stirred stayed right here and hooked onto this. This hydrogen sort of went right over there. And was this one this oxygen was this one right here and then my other oxygen went over. Just stayed here. So now I can look at my a pair from my water. Oxygen went over here, so that worked out very well. And we've got an electron pair donor right here. So this is my base, and this is my asset. Let me go check my problem and make sure I talked about everything. I think that's it. And that's under Louis. So I'll make sure to rate Lewis acid and Lewis base
