What else can I help you with?
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.
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.
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.
What do you call a material with definite properties and definite chemical composition?
A material with definite properties and definite chemical composition is called a pure substance.
What is the difference between law of conservation of mass and law of definite composition?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, but can only change form. The law of definite composition states that a compound is always composed of the same elements in the same proportions by mass regardless of the source of the compound.
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 !
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 a compound will always have the same proportion of elements by mass regardless of the source or how it was prepared. In the experiment, if the class obtained consistent results in terms of the mass of elements present in the compound, it would support this law. This consistency would demonstrate that the compound was formed with a fixed ratio of elements, reinforcing the idea that compounds have a definite composition.
Is the law of definite composition applicable to compounds only?
This law is not valid for all chemical compounds (ex. nonstoichiometric compounds).
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.
