Ammonia is an important chemical used in numerous industrial and household applications. Although ammonia is produced by natural processes, natural sources are not sufficient to meet industrial demand. Students will be conducting 3 (or 4) investigations in which they use mathematics and computational thinking to identify patterns to answer the driving question, “For a given chemical reaction, if we know the quantity of reactants, how can we predict the maximum possible yield of products and then later determine the efficiency of the reaction?”

Time Requirement
Total, 240 minutes. Teacher prep, 60 minutes. Pre-lab as homework, 20 minutes. Performing 3 investigations, 160 minutes.

Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.

Learning Objectives

  • Recognize patterns in mole ratios.
  • Employ stoichiometry to predict the amount of product a chemical reaction will produce.
  • Calculate percent yield and relate manipulation of a chemical reaction to its effect on yields.
  • Prerequisite Knowledge and Skills
    Students should be familiar with Avogadro’s number and be able to write and balance chemical equations; calculate molecular masses; and calculate moles in a compound when given mass, volume, or molecules.
