Which option is a correct example of the law of multiple proportions?

Answer and explanation

Correct answer: Methane (CH₄) and ethane (C₂H₆)

Methane and ethane are different compounds made from the same two elements, carbon and hydrogen. For a fixed mass of carbon, the masses of hydrogen that combine with it are in a simple whole-number ratio, as required by the law of multiple proportions. The other options are mixtures, not two compounds of the same elements.
