Use the interactive Annenberg Learner Simulation to Control a Haber-Bosch Ammonia Plant to explore how chemists manufacture ammonia from nitrogen and hydrogen for commercial purposes. How does varying temperature, pressure, or using a catalyst improve the yield, time to reach equilibrium, total output, and cost of the ammonia. Can you find an optimal solution where output is high and cost low?

(Aligns to) AP LAB #17 GUIDED INQUIRY — — Determine water impurities using gravimetric analysis — Phases IIU

Use the method of gravimetric analysis to determine the impurity levels in your five selected sources. Estimate your error and organize your data. If necessary, repeat tests and perform all necessary calculations to determine the level of impurities in your samples. File your formal report. Resources:
