(Originais Teachy 2024) - Question Hard of Chemistry

During the analysis of chemical compounds involved in ammonia synthesis reactions, a chemical engineer observes that when nitrogen reacts with hydrogen to form ammonia, the reaction can be represented by the equation N2(g) + 3H2(g) → 2NH3(g. Suppose that, after a synthesis reaction, a container contains 2.5 moles of N2 and 7.5 moles of H2, and the reaction occurs completely. Based on Dalton's Law of Multiple Proportions and the Law of Conservation of Mass: 1) Calculate the mass of ammonia (NH3) that would be produced from this reaction. 2) Analyze the implications of this law for atomic theory and for predicting the behavior of gases in chemical reactions and explain how the validity of this law can be experimentally tested.
