|
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: -The law of multiple proportions states that whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.
Detailed explanation-2: -Dalton’s law of multiple proportions states that if two elements combine to form more than one compound, the ratio of the mass of the second element is a small, whole number of a fixed amount of the first element. For example, nitrogen dioxide and nitrogen tetroxide have nitrogen to oxygen ratios of 1:2 and 1:4.
Detailed explanation-3: -The law of definite proportions, as the name indicates is a law that states about the definite ratio of masses of elements in a compound. Law of multiple proportions as the name indicates is a law that states about the ratio of an element in two compounds formed by the same elements.
