Hi there.
00:03
In this question, we are asked to classify each of these based upon the reaction type.
00:09
So as we're looking at our first one there, we see that it contains carbon and hydrogen.
00:17
It also contains an oxygen, but that is just kind of extra.
00:22
The important thing that we're interested in is that it contains carbon and hydrogen.
00:25
It's reacting with oxygen, and it's producing carbon dioxide gas and water vapor.
00:33
This is the general formula for a combustion reaction.
00:40
So what we have here is combustion.
00:45
In a combustion reaction, something containing carbon and hydrogen burns, or in other words, it reacts in oxygen, and it produces carbon dioxide and water.
00:56
All right, let's look at our next one.
00:58
Our next one has the general form where we have an element plus another element producing a compound.
01:08
When we have this general formula of two things combining to make a single product, so it could be two or more things combining, but the point is we get a single product.
01:19
What we have here, i might have already given it away because i said combining, this is a combination reaction.
01:28
And that is the only one of those terms that is going to apply here.
01:38
Let's look at our third one.
01:40
In our third one, we see that we have two, aqueous ionic compounds.
01:46
We have ab and we have x, y.
01:49
And the ions are exchanging partners.
01:53
A is combining with y and x is combining with b.
01:59
So what this is, is a double replacement...
