What law is described by the fact that the ratio of the mass of oxygen in carbon dioxide to the mass of oxygen in carbon monoxide is 2 to 1?

Answer 1

This statement illustrates the law of multiple proportions, which states that if two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

You can also put it this way: When two elements (A and B) combine to form more than one compound, the different masses of B that combine with a fixed mass of A are in a simple ratio.

Answer 2

I believe it is the 2nd law atoms of a given eelment are identical in their physical and chemical properties

Answer 3

This is the law om mass conservation.

Answer 4

This is known as the law of multiple proportions, which states that when elements combine to form compounds, the mass ratios of the elements in the compounds are simple whole number ratios.
