Question

Which statement describes the law of multiple proportions? For a collision occurring between two particles in an isolated system, the total momentum of the two particles before the collision is equal to the total momentum of the two particles after the collision. Energy cannot be created or destroyed, but may be changed from one form to another. When two elements react to form multiple compounds, the different masses of one element that combine with a O Mass in an isolated system is neither created nor destroyed by chemical reactions. O All samples of a given chemical compound will be composed of the same elements in the same proportion fixed mass of the other element can be expressed as a ratio of whole numbers.

Explanation / Answer

Option E is the correct answer

Law of multiple proportions

Statement of the law

When two elements form more than one compound then the ratio of mass of one element which combines with a fixed mass of other are simply whole numbers.

Ex -

N + 0.5O2 = NO

Mass of N : Mass of O = 14/14 : 16/14 = 1 : 1.143

N + O2 = NO2

Mass of N : Mass of O = 14/14 : 32/14 = 1 : 2.286

Law of multiple proportions

1.143/1.143 : 2.286/1.143 = 1 : 2 (whole number ratio)
