State the main postulates of Dalton's theory. Which postulate explains the
Law of conservation of mass/Law of constant proportion? What were the
main drawbacks of Dalton's theory?
Answers
Answer:
According to the 6th postulate of Dalton's atomic theory, atoms of each element are similar and have same weight and atoms of one element combine with atoms of another element to form compounds. Hence the sixth postulate explains the law of constant proportions. ... This is law of constant proportion.
Drawbacks of Dalton's Atomic Theory
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.
Explanation:
The postulate of Dalton's atomic theory that is the result of the law of conservation of mass is-the relative number and kinds of atoms are constant in a given compound. Atoms cannot be created nor destroyed in a chemical reaction.
