Which law compares the different compounds \(NO\) and \(NO_2\) made from nitrogen and oxygen?

Answer and explanation

Correct answer: Law of multiple proportions

The law of multiple proportions is used when two elements combine in more than one way to produce different compounds. With a fixed mass of one element, the masses of the other element in the compounds are related by a simple whole-number ratio. It therefore focuses on comparison between compounds with the same constituent elements.

Nitrogen monoxide, \(NO\), and nitrogen dioxide, \(NO_2\), contain nitrogen and oxygen but have different formulas. For the same amount of nitrogen, the oxygen combined in these compounds is in the ratio \(1:2\). This simple ratio shows multiple proportions. Hence option C, the law of multiple proportions, is the correct answer; conservation of mass addresses chemical reactions more generally.
