Which set of compounds illustrates the Law of Multiple Proportions?
A)NH₃, PH₃, AsH₃
B)CH₃, CF₃, CCl₃
C)NH₃, N₂H₄
D)all of these

Question

Quizplus · Accepted Answer

The Law of Multiple Proportions states that when two elements can form multiple compounds, the ratios of the masses of one element that combine with a fixed mass of the other element can be expressed in small whole numbers. In option C, the compounds NH3 and N2H4 both contain nitrogen and hydrogen, and the ratio of nitrogen to hydrogen in N2H4 is exactly twice that in NH3, satisfying the law of multiple proportions. The other options do not show this relationship.
