How is the law of multiple proportions different from the law of definite proportions?

The Law of definite proportions states that no matter how you make a chemical compound, it's got the same ratio of elements. An example: Whether you make water by combining hydrogen and oxygen or by decomposing hydrogen peroxide, the resulting water will still be 1 part by mass of hydrogen to eight parts by mass of oxygen. This seems obvious to us, but was pretty revolutionary back in Dalton's day. Back in the old days, chemical compounds frequently appeared to have different properties when made by different methods. We now know that this isn't because the compounds actually have different properties, but because when you use different methods to make chemical compounds and have low tech equipment, the different methods used cause different contaminants to be in the compound formed, making it appear as if it's a different compound with related, but different properties.
The law of multiple proportions refers to different chemical compounds that can be formed when two elements react with each other. For example, hydrogen and oxygen can react to form water (H2O) and hydrogen peroxide (H2O2). In the first compound, one gram of hydrogen combines with 8 grams of oxygen. In the second, one gram of hydrogen reacts with 16 grams of oxygen. If we look at the ratio of these to each other, 8/16 =2, which is a whole number. The law of multiple proportions says that whenever oxygen and hydrogen (or any two elements react to form more than one compound), the ratios of the elements to each other will be some whole number multiple of the ratios of the elements in the other compounds

∙ 7y agoLaw of definite proportions: the ratio between chemical elements in a chemical compound is always the same.
Law of multiple proportions: the ratio between two elements in a chemical compound (when these elements form more than one compound) is expressed in small whole numbers.

∙ 14y agoBoth 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.
For example: Carbon and oxygen can combine to form carbon monoxide and carbon dioxide. If you calculated each compounds ration of oxygen to carbon you would get the following ratios: compound A would equal a combining ratio of 1.34:1 (O:C). Compound B would equal a combining ratio of 2.67:1 (O:C).
If you divided the bigger ratio by the smaller ratio you would have that oxygen combines with a ratio of 2.67/1.34 which would equal 1.99:1, which is close enough to 2:1.

∙ 13y agoLaw of definite proportion says, a compound has same elements in the same proportion by mass.
Law of multiple proportion says, sometimes, two elements can combine in more than one ways to form different compounds.

What laws provided evidence for the existence of atoms?
The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.
Laws of chemical conbination?
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.
The law of multiple proportions can be partly explained by the idea that?
The law of multiple proportions can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
Who wrote the law of definite proportions and Law of multiple proportions?
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
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.
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
'Law of multiple Proportion was discovered by whom?
The Law of Multiple Proportions was proposed by John Dalton.
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?
Law of definite proportion, sometimes also called the law of constant composition.
Who developed the multiple proportions law?
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
What laws provided evidence for the existence of atoms?
The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.
When was the law of definite proportions developed?
The law of definite proportions was developed by Joseph Proust in 1806.
The difference between law of definite proportions and law of multiply 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.
