Question

(i) 144 g of pure water is decomposed by passing electricity .16g of Hydrogen and 128 g of Oxygen are

obtained. Which Chemical Law is illustrated by this statement ?

(ii) Which Postulate of Dalton's Atomic Theory can explain the Law of Definite Proportion ?

(iii) Give one relevant reason why scientists choose 1/16 of the mass of an atom of naturally occurring

oxygen as the Atomic Mass Unit​

Answer 1

Answer:

Law of constant proprtion. so when 16 gm of hydrogen reacted with the 128 gm of oxygen It will lead to the formation of 144 gm of H2O . Therefore it verifies the law successfully . Law of Conservation of mass is confirmed h
