Q. Amongst the following statements, select the set having statements which was proposed by Dalton.
(1) All the atoms of a given element have identical properties including identical mass. Atoms of different elements differ in mass.
(2) When gases combine or reproduced in a chemical reaction they do so in a simple ratio by volume provided all gases are at the same T & P
(3) Chemical reactions involve reorganization of atoms. These are neither created nor destroyed in a chemical reaction.
(4) Matter consists of indivisible atoms

Solution:

Statements (1), (3) and (4) are of Dalton's theory.
Statement (2) - When gases combine or reproduced in a chemical reaction they do so in a simple ratio by volume provided all gases are at the same T & P represents Avogadro law.
