CHM 2045C Module Six Sample Exam

Part F Volume-Volume Stoichiometry 5 points

In the Haber process, nitrogen N₂ and hydrogen H₂ gases combine to give ammonia gas NH₃ as the only product. If 5.55 L of nitrogen gas completely reacts, calculate the volume of ammonia that is produced. Assume all volumes of gas are measured under constant conditions of 500 ^oC and 300 atm pressure. How many liters of hydrogen are required to complete react the 5.55L of nitrogen?

Part G Mass-Volume Stoichiometry 5 points

Potassium chlorate is used in the lab to make oxygen gas by the following (unbalanced) reaction:

KClO₃ à KCl + O₂

How liters of oxygen may be made from reacting 1.226 grams of Potassium chlorate?
