Consider the reaction of solid aluminum iodide and potassium metal to form solid potassium iodide and aluminum metal. The balanced chemical equation is AlI₃(s) + 3 K(s) → 3 KI(s) + Al(s). How many moles of aluminum are produced if 1.45 moles of aluminum iodide are reacted with 3.49 moles of potassium based on the balanced chemical equation?

The Haber-Bosch process is a very important industrial process. In the Haber-Bosch process, hydrogen gas reacts with nitrogen gas to produce ammonia according to the equation 3H₂(g) + N₂ (g)→2NH3(g) The ammonia produced in the Haber-Bosch process has a wide range of uses, from fertilizer to pharmaceuticals. However, the production of ammonia is difficult, resulting in lower yields than those predicted the chemical equation. 1.56 g H₂ is allowed to react with 10.1 g N₂, producing 2.25 g NH3.
