What are the five laws of chemical combination?
Law of conservation of mass: Mass is conserved in a chemical reaction. Law of definite proportions: Chemical compounds always contain the same elements in the same proportion by mass. Law of multiple proportions: When two elements form more than one compound, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers. Law of combining volumes: Gases react in simple numerical ratios of volumes. Avogadro's law: Equal volumes of gases at the same temperature and pressure contain the same number of molecules.

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?

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.
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.
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.
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
