Explain law of multiple proportions with example:

Explanation

According to the laws of multiple proportions, if two elements can combine to form more than one compound, the masses of one element that combine with a fixed mass of other element, are in the same ratio. For example hydrogen combine with oxygen to form two compounds, namely, water `(H_2 O)` and hydrogen peroxide `(H_2 O_2)`.
`underset(2g)("Hydrogen")+underset(16g)("Oxygen") to underset(18g)("water")`
`underset(2g)("Hydrogen")+underset(32g)("Oxygen") to underset(34g)("Hydrogen peroxide")`
Here, the masses of oxygen (i.e., 16g and 32g), which combines with a fixed mass of hydrogen (2g) bear a simple ratio i.e. `16: 32` or `1:2`.
