One of the statements of Dalton’s atomic theory is given below: “Compounds are formed when atoms of different elements combine in a fixed ratio” Which of the following laws is not related to this statement?
A. Law of conservation of mass
B. Law of definite proportions
C. Law of multiple proportions
D. Avogadro law
The law of conservation of mass states that there is no net change in the mass in a physical or chemical reaction. It also means that the number of atoms of each element on both sides of a balanced chemical equation is the same.
The law of definite proportions states that a given compound contains exactly the same proportion of elements by weight.
The law of multiple proportions states that when two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of the other element, are in the ratio of small whole numbers.
The Avogadro law states that equal volumes of all gases at the same temperature and pressure should contain equal number of molecules.
Concluding from these laws, options (i) and (iv) are not related to the given Dalton’s law.
