Well definite is broad and multiple is more exact that's about what I can think of

The law of definite proportions was developed by Joseph Proust in 1806.

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.

Dalton\'s principle of compounds supports 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.

For example the law of definite proportions.

Joseph Proust

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.

Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.

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.

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.

By the law of definite proportions.

He uncovered the Law of Definite Proportions, which stated that every pure chemical compound consists of elements in a definite proportion.

The Law of Multiple Proportions was developed by John Dalton based on the Law of Definite Proportions, was part of what laid the groundwork for his atomic theory, and for the basis of chemical formulas for compounds.


English chemist John Dalton

The Law of Definite Proportions was discovered by Joseph Louis Proust in the late 18th century. He observed that compounds always contain the same elements in the same proportion by mass.

Non stoichiometric compounds do not match to law of definite proportions.

always the same

The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.

This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.

This is the law of definite proportions: Joseph Proust, 1806.

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.

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.

Experimental data can be used to show that a compound obeys the law of definite proportions by determining the mass ratios of elements in the compound. By analyzing the masses of elements present in different samples of the compound and comparing them, one can show that the elements combine in specific, fixed ratios according to the law of definite proportions.

Both laws have to do with relating to Dalton's Atomic Theory. The only difference is that the Law of Definite Proportions deals with elements combining to form ONE compound in a simple whole number ratio. The Law of Multiple Proportions is comparing the same 2 elements that make up 2 different compounds, the division of these 2 ratios should equal a simple whole number ratio.

According to the law of definite proportions, any two samples of KCl (potassium chloride) will have the same ratio of potassium to chloride ions by mass. This means that the composition of KCl is fixed and consistent regardless of the amount of the substance present.

The law of definite proportions was proposed by the French chemist Joseph Proust in the late 18th century. It states that a compound will always contain the same elements in the same proportion by mass, regardless of the amount of the compound.

If the mass proportions of the original substances do not equal these definite proportions, there will something of one of the original substances be left over. Note that this is special, it could as well have turned out to be possible for substances to combine in any proportion. So we find the law of definite proportions. Now we should be baffled and wonder how on Earth could that be so? And then we could think of substances being made of small particles (atoms) or groups of such particles (molecules) to explain the laws of nature that we found. So the laws of definite proportions and multiple proportions are (partially) proof for the existence of atoms which combine into molecules. The laws are the real thing and atoms and molecules and their chemical formulas are the ideas we make to understand the laws.

Joseph Proust , a French chemist, discovered each pure compound has its own characteristic elemental composition. For instance, the ratio of the elements will never change regardless of the masses. For example, NaCl, will have a ratio of 1 to 1 no matter how big or small its 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.

The scientist who proposed the law of definite proportions was Joseph Proust. He stated that elements always combine in specific and fixed proportions by mass to form compounds.

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.

Joseph Proust was a French chemist (1754-1826) well known for the discovery of the law of definite proportions.

Joseph Louis Proust (1754-1826) was an important French chemist, known for the Law of definite proportions.

He deduced that from the law of definite proportions.

Pure water is always 11.2% H, and 88.8% 0 by mass

The law of definite proportions states that a compound always contains the same elements in the same proportion by mass. This means that the ratio of the masses of the elements in a compound is constant. This law is one of the fundamental principles of stoichiometry in chemistry.

The Law of Definite Proportions.

No. Magnesium oxide, MgO, is a compound, which means it is a pure substance, in which the magnesium and oxygen are present in definite proportions, in this case 1:1. This is in accordance to the law of definite proportions, which states that every pure substance always contains the same elements combined in the same proportions by weight. Also, magnesium ions have a charge of 2+ and oxide ions have a charge of 2-, so that one magnesium ion combined with one oxide ion balances to an overall charge of zero.

According to the law of definite proportions, the ratio of carbon to oxygen in carbon dioxide is fixed at 1:2. This means that for every 1 atom of carbon, there are 2 atoms of oxygen in carbon dioxide. This ratio remains consistent regardless of the source of carbon dioxide, such as automobile exhaust.

The law of definite proportions says that a reaction that has too much of one of the reactants will eventually stop because it will run out of the other reactant(s). This is also referred to as the law of constant composition.

This is an illustration of the law of constant composition, also known as the law of definite proportions, which states that a chemical compound always contains the same elements in the same proportions by mass. This law is a fundamental principle in chemistry and helps in understanding how elements combine to form compounds.

The laws of chemical combination are fundamental principles that govern the relationships between the quantities of reactants and products in a chemical reaction. The three main laws are the law of conservation of mass, the law of definite proportions, and the law of multiple proportions. The law of conservation of mass states that mass is conserved in a chemical reaction, meaning that the total mass of the reactants is equal to the total mass of the products. The law of definite proportions states that a compound always contains the same proportions of elements by mass. The law of multiple proportions states that when two elements combine to form multiple compounds, the mass ratios of the elements in the compounds are always in whole-number ratios.

If the mass proportions of the original substances do not equal these definite proportions, there will something of one of the original substances be left over. Note that this is special, it could as well have turned out to be possible for substances to combine in any proportion. So we find the law of definite proportions. Now we should be baffled and wonder how on Earth could that be so? And then we could think of substances being made of small particles (atoms) or groups of such particles (molecules) to explain the laws of nature that we found. So the laws of definite proportions and multiple proportions are (partially) proof for the existence of atoms which combine into molecules. The laws are the real thing and atoms and molecules and their chemical formulas are the ideas we make to understand the laws.

The statement that a chemical compound always contains the same elements in exactly the same proportions is called the law of definite proportions. This law states that a compound is always composed of the same elements in fixed mass ratios.
