What are the new settings for nitrogen and hydrogen?

Question

Quizplus · Accepted Answer

The balanced chemical equation shows that for every 28 lbs of nitrogen, 6 lbs of hydrogen are needed to produce 34 lbs of the product. Given that the product's weight is 204 lbs, we scale the reactants accordingly. Since 34 lbs of product require 28 lbs of nitrogen, for 204 lbs of product (204/34 = 6 times more), we need 28 lbs * 6 = 168 lbs of nitrogen. Similarly, for hydrogen, 6 lbs * 6 = 36 lbs. However, the question seems to ask for the settings based on a misunderstanding of the chemical equation's stoichiometry. The correct stoichiometry calculation leads to 168 lbs of nitrogen and 36 lbs of hydrogen, but the options provided suggest a different interpretation or calculation method not directly related to the stoichiometry given in the question. Therefore, based on the options provided and assuming a possible mistake in interpreting the question's intent or a typo, option A is chosen as it is the only option that somewhat aligns with the expected increase in reactants, albeit not matching the stoichiometric calculation directly.
