Dalton’s Atomic Theory and Conservation of Mass:
– Dalton’s Atomic Theory Postulate:
– Law of Definite Proportions: States that compounds are formed by combining elements in definite and fixed proportions by mass.

– Connection to Conservation of Mass:
– Conservation of Mass Principle: Asserts that in a chemical reaction, the total mass of the substances remains constant; mass is neither created nor destroyed.

– Correlation:
– The Law of Definite Proportions in Dalton’s theory directly stems from the Conservation of Mass principle.

– Explanation:
– Conservation of Mass implies that in any chemical reaction, the total mass of the substances before the reaction is equal to the total mass of the substances after the reaction.
– This aligns with Dalton’s idea that compounds always contain elements in fixed proportions by mass, indicating that during a reaction, the relative masses of the elements stay consistent, adhering to the principle of mass conservation.
