Hi there.
00:03
In this question, we are trying to determine which of these is a homogeneous mixture.
00:14
So let's define homogeneous mixture first of all.
00:17
A homogeneous mixture describes a mixture that is uniform throughout.
00:28
In other words, when you look at it, it just looks like one substance.
00:34
Homogeneous mixtures are also known as solutions.
00:41
So solutions are, of course, where solutes are dissolved, in solvents.
00:54
So again, this is talking about uniform things like salt water.
01:00
The salt is thoroughly dissolved in the water.
01:02
So that's a homogeneous mixture.
01:05
The other type of mixture is a heterogeneous mixture.
01:11
And it has visibly different parts.
01:16
Think about vegetable soup.
01:18
Vegetable soup would be a heterogeneous mixture because it has visibly different parts.
01:29
All right.
01:30
So in this question, we are trying to determine the homogeneous mixture.
01:36
So i am just going to talk about these.
01:40
I'm going to number them one through five as we talk about them.
01:43
All right.
01:44
So the first one, sugar water.
01:46
We don't have any more information than that.
01:48
But typically, unless you add too much of it, sugar is going to dissolve completely in water.
01:55
All right.
01:56
So that would give us a solution, which is a homogeneous mixture.
02:09
So it sounds like this first one is our answer.
02:12
But let's check the others and make sure...
