Amongst the following which is not a postulate of Daltons atomic theor...
1) Elements are composed of extremely small particles called atoms that are indivisible and indestructible
2)All atoms of a given element are identical; they have the same size, mass, and chemical properties
3) Atoms of 1 element are different from the atoms of all other elements
4)Compounds are composed of atoms of more than 1 element. The relative number of atoms of each element in a given compound is always the same.
5)Chemical reactions only involve the rearrangement of atoms. Atoms are not created or destroyed during chemical reactions.

Amongst the following which is not a postulate of Daltons atomic theor...
The answer is option 'B': Under identical conditions of pressure and temperature gases combine and give gaseous products in simple volume ratio.
Explanation:
Dalton's atomic theory was proposed by John Dalton in the early 19th century. It was a revolutionary theory that provided a basic framework for understanding the nature of matter. Dalton's theory consisted of several postulates, which were based on experimental evidence and observations.
Postulates of Dalton's atomic theory:
1. Matter is formed of indivisible atoms: According to Dalton's theory, matter is composed of tiny, indivisible particles called atoms. These atoms are the fundamental building blocks of all matter and cannot be created, destroyed, or divided into smaller particles during chemical reactions.
2. Atoms of the same element are identical: Dalton proposed that all atoms of a particular element are identical in their properties, including atomic mass. This means that atoms of the same element have the same number of protons, neutrons, and electrons.
3. Atoms of different elements are different: Dalton stated that atoms of different elements have different properties, including atomic mass. This means that atoms of different elements have a different number of protons, neutrons, and electrons.
4. Atoms combine in simple whole-number ratios: Dalton observed that elements combine to form compounds in specific ratios. He proposed that atoms combine in simple, fixed ratios to form compounds. For example, water (H2O) consists of two hydrogen atoms and one oxygen atom, always in a 2:1 ratio.
5. During chemical reactions, atoms are rearranged: According to Dalton's theory, chemical reactions involve the rearrangement of atoms. The atoms present in the reactants rearrange to form new compounds, but no atoms are created or destroyed in the process. The total number of atoms before and after the reaction remains the same.
Why option B is not a postulate of Dalton's atomic theory:
Option B states that under identical conditions of pressure and temperature, gases combine and give gaseous products in a simple volume ratio. However, this statement is not a postulate of Dalton's atomic theory. Dalton's theory primarily deals with the behavior and properties of atoms, not the volume ratios of gases during chemical reactions.
The statement in option B is actually a postulate of Avogadro's law, which states that equal volumes of gases, under identical conditions of pressure and temperature, contain the same number of molecules. This law was proposed by Amedeo Avogadro in the early 19th century and is unrelated to Dalton's atomic theory.
To summarize, option B is not a postulate of Dalton's atomic theory because it pertains to the volume ratios of gases, which is a separate concept explained by Avogadro's law.
