Which postulate of Dalton's atomic theory can explain the law of definite proportions?

(d) (i), (ii) and (iv)

The postulate of Dalton's atomic theory which is a result of the law of conservation of mass is “Atoms are indivisible particles, which can neither be created nor destroyed in...

The postulate of Dalton's atomic theory which can explain the law of definite proportion is “The relative number and kind of atoms in a given compound remains constant”

The law of constant proportions states “a pure chemical compound always consists of the same elements that are combined together in a fixed proportion by mass.”  For example, H2O obtained from...

Axiom 5 : ‘Whole is always greater than its part.’  This is a ‘universal truth’ because part is included in the whole and therefore can never be greater than the whole...

When two lines are cut by a third line, such that the sum of interior angles is less than 180° on one side then the first two lines intersect on...

It may be argued that Euclid’s fifth postulate recognises the existence of parallel lines. If the sum of interior angles is 180° on both sides of the transversal then the...

We never speak of quantization of orbits of planets around the Sun because the angular momentum associated with planetary motion is largely relative to the value of Planck’s constant (h). The...

The correct answer is (2) Mycoplasmas are smallest, prokaryotes lacking cell wall and are pleomorphic in nature. These are pathogenic to both plants and animals.
