Joseph Proust, based on experiments conducted at the end of the 18th Century claimed that elements combined in constant proportions. Dalton's atomic theory, (1903) built on this earlier work and put it into a theoretic framework.

Does compound follow the law of constant composition?

What in an expression of Dalton's law constant?
Dalton's law of constant proportion states that any sample of a chemical compound will have its constituent elements appearing in the same proportion by mass. Thus 8/9 of the mass of any sample of water will be oxygen and the remaining 1/9 will be hydrogen.
Atoms of different elements combine in whole number what?
That is the law of constant composition.
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
Why is the law of constant composition important to chemistry?
It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.
Who stated the law of constant composition?
Joseph Proust, a French chemist, is credited with stating the law of constant composition, which states that a given chemical compound is always composed of the same elements in the same proportions by mass.
Who was the scientist that helped prepare the way for daltons work by developing the law of constant composition?
The scientist who helped prepare the way for Dalton's work by developing the law of constant composition was Joseph Proust. Proust formulated this law, also known as the law of definite proportions, which states that a given compound always has the same elements in the same proportion by mass.
Who put forward the law of constant proportion?
This was an idea of John Dalton.
If Law of constant composition true for all types of compounds?
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
What is an expression of Dalton's law constant?
Answer: Apex ↓Ptotal = P1 + P2 + P3 + ...
Who proposed a given compound always has the same relative numbers and kinds of atoms?
The law of constant composition, proposed by Joseph Proust, states that a compound always has the same relative numbers and kinds of atoms regardless of its source or method of preparation. This law forms the basis of modern stoichiometry in chemistry.

Atoms of different elements combine in whole number what?
That is the law of constant composition.
Who wrote the law of definite proportions and Law of multiple proportions?
The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.English chemist John Dalton

What was John Dalton contributes in atomic theory?
It explained law of conservation of mass and law of constant proportion and laid foundation to atomic physics n chemistry...
