What theory states that a given compound will always contain exactly the same proportion of elements by weight?
Law of definite proportion or law of definite composition.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
Law of definite proportion, sometimes also called the law of constant composition.
Explain how your class's results in this experiment support the law of definite composition?
"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.
Examples of the law of definite composition?
formation of water and hydrogen peroxide , carbon dioxide and carbon monoxide are the big examples of law of definite proportion
State the law of definite proportions?
The law of definite proportions states that all chemical compounds have constant proportions of their components.
How is the Law of definite composition and proportion relate to the empirical formula?
empirical formula is the simple whole number ratio of the components.
Why is the law of definite proportion important.?
In chemistry, the law of definite proportions, 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 by mass. For example, oxygen makes up about 8/9 of the mass of any sample of pure water, while hydrogen makes up the remaining 1/9 of the mass. Along with the law of multiple proportions, the law of definite proportions forms the basis of stoichiometry.
Who stated the law of constant composition?
Joseph Louis Proust (1754-1826), In 1799 Proust stated that "Compounds always contain the same elements in a constant proportion by mass." This statement is now called law of definite composition or the law of constant proportion.
Is the law of definite proportions says that the composition of a compound always the same?
always the same
Who developed the law of definite composition?
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:
