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.
Does The Law of Definite Proportions state that substances combine in predictable proportions and that excess reactants remain unchanged?
The Law of Definite Proportions states that chemical compounds always contain the same elements in the same proportions by mass. It does not specifically address what happens to excess reactants in a chemical reaction.
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 discovered Law of Definite Proportions?
He combined elements such as iron and copper with oxygen, based off the reaction he found that oxygen's composition was always one of two.
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
What is the name of the chemical law?
For example the law of definite proportions.
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.
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
Which of Dalton's four principles support law of definite proportions?
Dalton\'s principle of compounds supports the law of definite proportions.
What year did Joseph Proust make the law of definite proportions?
In was in 1799 that Joseph Proust discovered the law of definite proportions, or Proust's Law. Proust was a French chemist.
1 Differentiate between The Law of Definite Proportions and The Law of Multiple Proportions?
Well definite is broad and multiple is more exact that's about what I can think of
Who developed the law of Definite Proportions?
Joseph Proust
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 quantity of oxygen in brown lead oxide is always twice as great as the quantity of oxygen in yellow lead oxide this is an example of which law?
The Law of Definite Proportions.
Is the law of definite proportions important?

The law of definite proportions states that a compound always contains the same elemtents in the smae proportions?
true
What did Proust do?
Joseph Louis Proust eleborated the Law of definite proportions.
