Hi there.
00:03
In this question, we have two elements.
00:06
We have element a, which we are told to use triangles to represent a.
00:13
And we have element b.
00:16
We're told to use circles to represent that.
00:19
Of course, if we're trying to show the compound a, b, we would need to attach these two together.
00:27
We'd be attached to each other.
00:29
So that would be a .b.
00:32
All right, with these things in mind, let's go ahead.
00:35
And answer these questions.
00:38
So the first thing we need to do is to draw an atomic view of homogeneous mixture of a and b.
00:51
So for a homogeneous mixture, i'm going to draw a little box here.
00:57
This is going to be our homogeneous mixture.
01:05
I'm going to draw these in the gas state because that's probably the easiest way to show them uniformly dispersed through each other because that's what a homogeneous mixture is.
01:16
It is uniform.
01:19
So remember in a gas, the particles are in constant random rapid motion, so they would be evenly dispersed through each other.
01:28
So that would be a homogeneous mixture.
01:34
The next thing we want to show is the compound ab in the liquid state.
01:41
So in the liquid state, the molecules are going to be close together.
01:43
They're going to be touching.
01:46
If this is a beaker i'm drawing here, they would be at the bottom of that because gravity acts upon a liquid.
01:56
And remember, since they are the compound, we want to show circles and triangles attached to each other.
02:09
So these particles are attached to each other.
02:13
They are touching.
02:15
Gravity is acted upon them, so they're at the bottom of their container...
