Statement-I : Law of conservation of mass hold good for nuclear reaction. Because Statement-II : Law states that mass can be neither created nor destroyed in a chemical reaction.

Amongst the following statements, select the set having statements which was porposed 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 reaction involve reorganization of atoms. These are neither created nor destroyed in a chemical reaction. (4) Matter consists of indivisible atoms
