Explanation:

Which of the following pairs of substances best illustrates the law of multiple proportions?

A. H2 and O2

B. NO and NO2

C. P2O5 and PH3

D. CaCl2 and CaBr2

B. NO and NO2

best shows the law of multiple proportions.

law of simple multiple proportions. Law of multiple proportions, states that when two elements react with oneaother to form more than one compound, the weights of one element that combine with the fixed weight of the other element are in small whole number ratios.

Here Nitrogen, N which is fixed combines with Oxygen in two compounds in ratios 1 to 1 and 1 to 2

1. they vary with a higher number because boiling is way hotter than melting
