what is law of Definite proportions​

Answer 1

Explanation:

$\huge{\pink{\underline{\underline{Answer\implies}}}}$

The law of definite proportion, sometimes called Proust's law, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.

⇴In chemistry, the law of definite proportion, sometimes called Proust's law, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.

⇴Law of definite proportions: It states that a given chemical substance (compound) always contains the same elements combined in a fixed proportion by weight.

⇴It is also called the law of constant composition.

⇴The law of combining volumes was given by Gay Lussac in 1808. It is applicable only to a gaseous reaction.

⇴ According to this law, gases combine or are produced in a chemical reaction they do so in a simple ratio by volume provided all gases are at same temperature and pressure.

⇴ So, the law of definite proportions when expressed in terms of volumes becomes 'Gay-Lussac's Law'.  

⇴Avogadro's law states that 'equal volumes of all gases, at the same temperature and pressure, have the same number of molecules'.

⇴According to Berzelius hypothesis, equal volumes of all gases contain an equal number of atoms under similar conditions of temperature and pressure.
