So let's start with the law of conservation of mass.
00:04
This is best explained by looking at a chemical reaction.
00:07
So in this case, the reaction that forms water.
00:11
We have hydrogen molecules and oxygen molecules combining to form h2o or water.
00:16
The law of conservation of mass states that whatever mass you have is your starting materials, so hydrogen and oxygen, you'll have the same mass in your ending material or water.
00:27
You can't get rid of any mass and you can't create any new mass.
00:31
The amount of mass you have will always be the same, or conserved.
00:36
Next, let's look at the law of definite proportion.
00:40
This law states that a chemical compound will always have the same proportions of each element by weight...
