Question

Which postulate of dalton atomic theroy can explain the law of definitevproportions?

Answer 1

1. An atom is the basic buildingblock of matter .
2. atims cannot be subdivided.,created,or destroyed.
3. all the atoms of a given element show identical properties such as size,mass and chemical properties.
4. in chemical reaction , atoms are combined,seperated or rearranged

Answer 2

Answer:

The postulate of Dalton's atomic theory that can explain the law of definite proportions is - the relative number and kinds of atoms are equal in given compounds.

Explanation:

Law of definite proportion states that "the elements are always present in definite proportions by mass."

And we know that the last postulate of Dalton's atomic theory which states that, "In a given compound, the relative number and types of atoms are constant."

This postulate can explain the law of definite proportions.
