Basic Stoichiometry Post-Lab Homework Exercises 1. Load the "Reactants, Products, and Leftovers" simulation and work through each of the levels of the Game! At
home, you can find the simulation by going to http://phet. colorado. edu/or googling "phet." You may have to download or
update the version of Java on your computer.
Complete each exercise on your own. Remember to use proper units and labels.
2. For the reaction N, +_ 0, → __NO, determine the correct lowest mole ratio.
3.
For the reaction_SO, +_0, →_SO, determine the correct lowest mole ratio.
4.
For the reaction P, +6C1, +4PC1z, determine how many moles of chlorine Cl, would be needed to react with
3 moles of phosphorus PA to entirely use up all the phosphorus.
4)
5. If 5 moles of Pa reacted with 22 moles Cl, according to the above reaction, determine:
a) How many moles PCI; are produced
b) How many moles of P are left in excess after the reaction (if any)
b)
c) How many moles of Cl, are left in excess after the reaction (if any)
