Concept: Law of Multiple Proportions

Problem: Observations of the reaction between nitrogen gas and hydrogen gas show us that 1 volume of nitrogen reacts with 3 volumes of hydrogen to make 2 volumes of gaseous product, as shown below:Determine the formula of the product and justify your answer.

Volume → proportional to moles → stoichiometric coefficient


Reaction: N2 + 3H2  → 2NxHy

reactant        products

N - 2             2x → x = 2

H - 6            2y → y = 3

The balanced equation for the reaction is: N2 + 3H2  → 2NH3
