Law of Multiple Proportions When two

Dalton noted that compound II contained twice as much oxygen per gram of carbon as compound I, a fact that could be easily explained in terms of atoms. Compound I might be CO, and compound II might be CO2. This principle, which was found to apply to compounds of other elements as well, became known as the law of multiple proportions When two elements form a series of compounds, the ratios of the masses of the second element that combine with 1 gram of the first element can always be reduced to small whole numbers. 

Law of Multiple Proportions When two elements, A and B, form more than one compound, the ratio of the masses of element B that combine with a given mass of element A in each of the compounds can be expressed by small whole numbers. 

Law of multiple proportions when two elements form a series of compounds, the ratios of the masses of the second element that combine with one gram of the first element can always be reduced to small whole numbers. (2.2)... 

Law of Multiple Proportions When two elements combine to form two or more compounds, the masses of one combining with a fixed mass of the other are in ratios of small whole numbers (as illustrated for two compounds composed only of carbon and hydrogen below). 

Atoms of constituent elements in a particular compound are always combined in the same proportions by mass (law of definite proportions). When two elements can combine to form more than one type of compound, the masses of one element that combine with a fixed mass of the other element are in a ratio of small whole numbers (law of multiple proportions). 

The Law of Multiple Proportioxs.— When two elements unite with each other to form more than one compound, the resulting compounds contain simple multiple proportions of one element as compared with a constant quantity of the other. 

The law of multiple proportions. When the same elements can form two different compounds, the ratio of masses of one of the elements in the two compounds is a small whole number relative to a given mass of the other element. 

As a result of his work on relative weights, Dalton formulated the Law of Multiple Proportions, which states that when elements combine to form more than one compound, then the ratio of the masses of elements in the compounds are small whole number ratios of each other. For example, the elements carbon and oxygen form the two compounds carbon monoxide (CO) and carbon dioxide (CO ). The ratio of...

By then the French chemist, Joseph Louis Proust, had discovered that whenever elements form compounds these are always of a very definite composition —- the Law of Definite Composition. Water molecules, for example, always contain the same number of hydrogen and oxygen atoms. And Dalton had found that when two elements combine in different ways they do this in simple proportions — the Law of Multiple Proportions. One atom of carbon and one atom of oxygen make carbon monoxide one atom of carbon and two atoms of oxygen make carbon dioxide. 

Chemical formulas such as CO and C02 reflect an important law called the law of multiple proportions. This law applies when two elements (such as carbon and oxygen) combine to form two or more different compounds. In these cases, the masses of the element (such as 02 in CO and C02) that combine with a fixed amount of the second element are in ratios of small whole numbers. For example, two moles of carbon can combine with one mole of oxygen to form carbon monoxide, or with two moles of oxygen to form carbon dioxide. The ratio of the two different amounts of oxygen that combine with the fixed amount of carbon is 1 2. 

The Law of Multiple Proportions states that when two or more different compounds are formed from the same elements, the ratio of masses of each element in the compounds for a given mass of any other element is a small whole number. 

The Law of Simple Multiple Proportions. When two elements combine to form more than one compound, the weights of one element which combine with the same weight of the other are in the ratios of small integers. 

Dalton described a phenomenon that occurs when two elements form more than one compound. His observation is now called the law of multiple proportions i f elements A and B react to form two compounds, the different masses of B that combine with a fixed mass of A can be expressed as a ratio of small whole numbers. Consider two compounds that form from carbon and oxygen for now, let s call them carbon oxides I and II. They have very different properties. For example, measured at the same temperature and pressure, the density of carbon oxide I is 1.25 g/L, whereas that of II is 1.98 g/L. Moreover, I is poisonous and flammable, but II is not. Analysis shows that their compositions by mass are... 

The Law of Multiple Proportions states that when two elements combine to form two or more different compounds, the weights of one compound that can combine with a given weight of the second compound form small whole number ratios. For example, consider one experiment in which...
