Question

The combining ratios of hydrogen and oxygen in water and hydrogen peroxide are 1 : 8 and 1 : 16. Which law is illustrated in this example?

Options

• Law of definite proportions

• Law of conservation of mass

• Gay Lussac's law of combining volumes of gases

• Law of multiple proportions

Answer 1

Law of multiple proportions

Explanation:

The hydrogen and oxygen combining ratios in water and hydrogen peroxide are 1 : 8 and 1 : 16, respectively.

It's an illustration of the law of many proportions. If two elements mix to make numerous compounds, then the weight of one of these elements, which combines with a fixed weight of the other, is in a ratio of simple whole numbers, according to this law.
