yes it dose.
In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition.This observation was first made by the French chemist Joseph Proust based on several experiments conducted between 1798 and 1804. Based on such observations, Proust made statements like this one, in 1806:

First find out what the law of definite proportions is. Then explain the fact that water and hydrogen peroxide consist of the same elements. Then find out if they have different or the same properties.
Generally yes (the law of definite proportions); as exceptions - nonstoichiometric compounds.
No. For Ohm's Law to apply, the ratio of voltage to current must remain constant for variations in voltage. This simply doesn't happen with a tungsten filament. In fact, MOST materials don't obey Ohm's Law.
Law of definite proportion, sometimes also called the law of constant composition.
yes it is .. also called prousts law
This law hasn't a chemical equation !
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
Law of definite proportion or law of definite composition.
formation of water and hydrogen peroxide , carbon dioxide and carbon monoxide are the big examples of law of definite proportion
Well the difference is, TRIANGLE IS THE ANSWER TO EVERYTHING!
always the same
The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.
The Law of Multiple Proportions states that two or more compounds may be made from the same elements but each compound will obey the Law of Definite Proportions. Combining two elements to create another element can only be done with precise measurements of each element or another element would be created instead of the one intended.
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
"The Law of Definite Composition states that the elements in a given compound are always combined in the same proportion by mass."All of the students in our class had different values for the mass of the hydrate and anhydrous salt, but all calculated the same formula for the hydrate. By everyone calculating the same formula for the hydrate, the law of definite composition was proved.
