|
when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers
|
|
|
that every chemical compound contains fixed and constant proportions (by mass) of the elements that make up that compound.
|
|
|
that matter is neither created nor destroyed, only changed during chemical reactions
|
|
|
None of the above

Detailed explanation-1: -In chemistry, the law of multiple proportions states that if two elements form more than one compound, then the ratios of the masses of the second element which combine with a fixed mass of the first element will always be ratios of small whole numbers.
Detailed explanation-2: -His law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.
Detailed explanation-3: -The law of multiple proportions states that, when two elements combine to form more than one compound, the mass of one element, which combines with a fixed mass of the other element, will always bear a simple ratio to the other.
Detailed explanation-4: -John Dalton (1803) stated, “’When two elements combine with each other to form two or more compounds, the ratios of the masses of one element that combines with the fixed mass of the other are simple whole numbers’.
Detailed explanation-5: -Summary. The law of definite proportions states that a given chemical compound always contains the same elements in the exact same proportions by mass.
