In this question we are trying to determine our reaction type.
00:08
We have five basic reaction types that you have learned.
00:12
One is synthesis or combination.
00:19
It just depends upon your textbook as to which of the terms it uses.
00:23
The two terms mean the same thing.
00:26
The reverse of synthesis is decomposition.
00:31
That's our second reaction type.
00:35
Next we have single replacement, double replacement, and combustion.
00:58
For these five reaction types we have a basic pattern that each one follows.
01:08
Synthesis or combination is just what the name implies.
01:13
We are taking two or more simpler substances and combining them to synthesize a single product.
01:22
Decomposition is the reverse of that.
01:24
We start with a single reactant and we break it apart into two or more simpler substances.
01:31
For a single replacement we have an element reacting with a compound.
01:37
The element replaces one of the elements in the compound.
01:42
It would have this general formula.
01:44
Double replacement has two ionic compounds that are aqueous.
01:51
What they do is they exchange ions.
01:53
We have a double replacement going on here...
