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.
Are the elements that make up a compound joined in a fixed proportion?
This is an old rule (Law of definite proportions) not valid for 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. 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.
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.
What chemical union for two or more elements in definite proportion's?
This is a chemical reaction.
Is the law of definite composition the same as the law of definite proportion?
yes it is .. also called prousts law
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 an example of the law of definite proportion?
All stoichiometric compounds.
What law did Joseph Proust uncover?
He uncovered the Law of Definite Proportions, which stated that every pure chemical compound consists of elements in a definite proportion.
Does adding coefficients to a chemical equation disobey the law of definite proportion?
No, adding coefficients to a chemical equation does not disobey the law of definite proportion. The coefficients simply represent the relative number of moles of each substance involved in the reaction and do not alter the proportion of elements present in the compounds.
'Law of multiple Proportion was discovered by whom?
The law of multiple proportions was proposed by John Dalton in the early 19th century. It states that when elements combine to form compounds, the ratio of masses of one element that combines with a fixed mass of the other element can be expressed in small whole numbers.
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.
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.
Define law of definite proportion?
Law of Conservation of Mass is a relation stating that in a chemical reaction, the mass of the products equals the massof the reacants.
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.
Are the elements that make up a compound joined in a fixed proportion?
This is an old rule (Law of definite proportions) not valid for nonstoichiometric compounds.
What is the identification of a law that states elements in a compound follow a fixed mass ratio to form a compound?
This is Dalton's law of definite proportions. It sounds esoteric, but it just means that the same substance always has the same formula.
