Answer 1

law of multiple proportions...
this may help u........

Answer 2

It follows the law of multiple proportions

• This law states that "If two elements form more than one compound between them, the mass ratios of the second element that combine with a fixed mass of the first element will always be the ratios of small whole numbers".
• This law is also referred to as Dalton's law.
• It was proposed in the year 1803.
• The atoms of the given element are identical in properties and mass
• The atoms are indestructible and indivisible
• The chemical reaction formed is a rearrangement of the atoms
• ex) iron - Fe and Oxygen - O. They form various compounds when combined in different ratios, as given in the question
• Hence the law proved here is law of multiple proportions
