Physical Science 20 - March 16

Today in class, we then learned how to do limiting reactant problems. These types of problems occur when we are given a certain amount of each reactant and we have to determine which one limits the amount of product formed.  The one that does is called the limiting reactant.  This involves doing stoichiometry twice, with each separate reactant to determine an amount of a certain product formed.  Whichever reactant yields the lower amount of product will be the limiting reactant.  This was all covered on slides 16-24 in the notes.  After we went over an example,  students were given time to work on Assignment C25 and questions 15 and 16 from C24.  We will go over these questions on Monday.  Reminder that tomorrow is your first unit exam on Nomenclature, Reactions and the Mole.
