Question

Which law is also known as Law of constant composition?a)Law of multiple proportionsb)Avogadro&#8217;s lawc)Law of conservation of massd)Law of definite proportionsCorrect answer is option 'D'. Can you explain this answer?

Answer

law of constant proportion simply means if there is a compound example H20 (water) the ratio of hydrogen n oxygen will be fixed 2:1 for all the compounds of water(H2O) in the world .. or simply law of definite proportion

Answer

Correct option is D
law of constant composition or definite proportion
states that the composition of elements in a given compound always exist in a definite proportion by their mass independent of the source from which it is obtained.

Answer

Law of constant composition means that reactions are react in definite proportion ... thus , this law is also known as law of definite proportion

Answer

Law of definite proportion

Answer

The law of definite proportions, also known as the law of constant composition states that all pure samples of the same chemical compound contain the same elements combined in the same proportions by mass.
What this law emphasizes is that, if pure samples of the same chemical substance, wherever they may be found, are analyzed, it will be found that they all consist of the same elements, as well as having these elements combine in the same proportions by mass.
For examples, pure sample of copper(II) oxide is composed of copper and oxygen, in the proportion of 1:1 by mole, or 64 g of copper to 16 g of oxygen or 1 g of copper to 0.25 g of oxygen.

Answer

Law of Definite Proportions:
The law of definite proportions, also known as the law of constant composition, states that a chemical compound always contains the same elements in the same proportions by mass. This means that, regardless of the source or how the compound was prepared, a compound will always have the same composition of elements.

Explanation:
- This law was first proposed by Joseph Proust in the late 18th century based on his experiments with chemical compounds.
- The law of definite proportions helps in identifying and characterizing different compounds based on their unique elemental composition.
- For example, water (H2O) will always consist of two hydrogen atoms and one oxygen atom in a fixed ratio of 2:1 by mass.
- This law is crucial in understanding the fundamental principles of stoichiometry and chemical reactions.
- It also serves as the basis for modern analytical techniques used in chemistry to determine the composition of unknown substances.

Significance:
- The law of definite proportions provides a foundation for understanding the nature of chemical compounds and their behavior.
- It allows scientists to predict the composition of compounds and helps in the synthesis of new materials with specific properties.
- This law is essential in various fields of chemistry, including analytical chemistry, inorganic chemistry, and materials science.
- It highlights the consistent and predictable nature of chemical compounds, which is vital for advancements in the field of chemistry.
In conclusion, the law of definite proportions, or the law of constant composition, is a fundamental principle in chemistry that states that a compound always contains the same elements in the same proportions by mass. Understanding this law is crucial for various aspects of chemical analysis, synthesis, and research.
