Dinitrogen and dioxygen are N2 and O2, which are gases at STP. The reaction proceeds to form N2O. The ratios of the reactant and products are 45.4:22.7:45.4, which is equal to 2:1:2.
The ratio has small whole numbers and is simple. Hence the experiment follows the Gay-Lussac’s law of gaseous volumes, which states that when gases combine or produced in a chemical reaction they do so in a simple ratio by volume, provided all gases are at the same temperature and pressure.
