When 3.0 L of hydrogen gas (H₂) reacts with 1.0 L of nitrogen gas (N₂), 2.0 L of gaseous product is formed. All volumes of gases are measured at the same temperature and pressure. What is the formula of the product?

By the ideal gas law, the volume ratio of reactants to products is the same as the mole ratio. Therefore, we need to find the mole ratio of the reactants and products in order to determine the formula of the product. From the balanced chemical equation for the reaction of hydrogen and nitrogen to form ammonia (NH3), we know that the mole ratio of hydrogen to nitrogen to ammonia is 3:1:2. So, if 3.0 L of hydrogen gas (H₂) reacts with 1.0 L of nitrogen gas (N₂), we would expect to produce: 2.0 L of ammonia gas (NH3) However, the answer choices do not include NH3. We can use the same approach as above to determine the mole ratio of the reactants and products for some of the other possible products: - For N₃H: The mole ratio of hydrogen to nitrogen to NH is 3:2:0, so this is not the correct formula. - For NH₄: The mole ratio of hydrogen to nitrogen to NH is 0:0:1, so this is not the correct formula. - For N₂H₃: The mole ratio of hydrogen to nitrogen to NH is 3:1:1, so this is not the correct formula. - For NH₃: The mole ratio of hydrogen to nitrogen to NH is 3:1:1, which matches the expected mole ratio. Therefore, this is the correct formula of the product that is formed.
