Question

How does the Dalton's atomic theory explain the mass law?

Answer 1

Explanation:

•Dalton based his theory on two laws:

the law of conservation of mass and the law of constant composition. The law of conservation of mass says that matter is not created or destroyed in a closed system. The law of constant composition says that a pure compound will always have the same proportion of the same elements.

•Since Law of conservation of mass states that atoms cannot be created or destroyed, Dalton's theory suggests that the net mass of the participating species in a chemical reaction is conserved. This postulate, therefore, accounts for the law of conservation of mass.

Answer 2

Answer:

The law of constant composition says that a pure compound will always have the same proportion of the same elements.
