What else can I help you with?
Is the law of definite composition the same as the law of definite proportion?
yes it is .. also called prousts law
Does a mixture obey the law of definite composition?
Yes, a mixture does not obey the law of definite composition. Mixtures can have varying proportions of different substances, whereas compounds, which obey the law of definite composition, have a fixed ratio of elements.
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?
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
What is the chemical equation of the law of definite composition?
This law hasn't a chemical equation !
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.
Is it true that a chemical has a definite composition?
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
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.
How is the Law of definite composition and proportion relate to the empirical formula?
The Law of Definite Composition states that a compound will always have the same proportion of elements by mass. This relates to the empirical formula because the empirical formula gives the simplest whole number ratio of the elements in a compound, which reflects the fixed composition of elements as per the Law of Definite Composition.
Is the law of definite proportions says that the composition of a compound always the same?
always the same
What you mean by nonstoichiometry?
The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.
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.
Is the law of definite composition applicable to compounds only?
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
