Hi guys, let's do problem 10.
00:02
In this problem we need to explain how the dalton's theory explain the law of conservation of mass and the law of constant composition.
00:14
Let's start with the law of conservation of mass and the law is that matter can either be created or destroyed.
00:29
Created or destroyed.
00:35
Therefore, the mass is conserved in a chemical reaction.
00:54
Now the dalton's atomicant theory is that the theory says that matter is made up of indestructible atoms we cannot hamper these items matter is made up of and the atoms of one element cannot be destroyed or they cannot be changed into another into atoms of another element therefore, this dalton's sartemic theory, it explains the law of conservation of mass in this way that the atoms of one element cannot be changed into atoms of another element.
02:43
They can the attachment between the atoms, it can be changed by in the chemical reaction.
02:50
However, the atoms of one element they cannot be changed into atoms of another element.
02:57
Therefore, in a chemical reaction, the atoms of one element cannot be changed into atoms of another element.
03:39
Only the attachment between the atoms changes.
03:55
We can look up to a very simple example.
04:01
We can consider the reaction between...
