What was Antoine Lavoisier important discovery?
He discovered that the phlogiston theory was incorrect, and recognized and named oxygen and hydrogen. He accepted that sulfur is an element, had contributions to metric system, established a list of chemical elements, discovered that diamond is a form of carbon, discovered that water is formed from oxygen and hydrogen, etc.He proposed independently (he had any knowledge of Lomonosov works) the law of mass conservation.Joseph Proust is credited with the discovery of the Law of definite proportions.
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.
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
How are experimental data used to show that compound obeys the law of definite proportions?
The Law of Multiple Proportions states that two or more compounds may be made from the same elements but each compound will obey the Law of Definite Proportions. Combining two elements to create another element can only be done with precise measurements of each element or another element would be created instead of the one intended.
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.
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
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.
Which of Dalton's four principles support law of definite proportions?
Dalton\'s principle of compounds supports the law of definite proportions.
What is the name of the chemical law?
For example the law of definite proportions.
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.

true
What did Proust do?
Joseph Louis Proust eleborated the Law of definite proportions.
