Question

Which law is illustrated by compounds H$_2$O and H$_2$O$_2$ formed from two different elements, H and O?

• A. Law of Constant proportion
• B. Law of Conservation of mass
• C. Law of Multiple proportion
• D. Avogadro's law

Hint:

Remember, the law of multiple proportions involves elements combining in different ratios to form different compounds.

Answer 1

The Correct Option is C

The law of multiple proportions states that when two elements combine in more than one proportion to form different compounds, the masses of one element that combine with a fixed mass of the other element are in simple whole number ratios. H$_2$O and H$_2$O$_2$ are examples of compounds formed by the combination of hydrogen and oxygen in different proportions, hence they illustrate this law.
