What else can I help you with?
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?
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.
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.
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.
State the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
The scientific statement that says that compounds always have exactly the same composition by mass is?
The law of definite proportions states that compounds always contain the same elements in the same proportion by mass. This means that the ratio of elements in a compound is consistent and does not change.
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.
Is the law of definite proportions says that the composition of a compound always the same?
always the same
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.
What law is described by the fact that carbon dioxide consists of 27.3 carbon and 72.7 oxygen by mass?
The Law of Definite Proportions Henry Foss All Day!
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 developed the law of definite composition?
The law of definite composition was developed by French chemist Joseph Proust in the late 18th century. He formulated this law based on his experiments with chemical compounds, which stated that a given compound always contains the same elements in fixed proportions by mass.
