Lecture 10 (9/16/20)

In this lecture we will be continuing our investigation of limiting reactants and performing calculations to determine the limiting and excess reactants. We will also use the limiting reactant to determine the theoretical yield of the reaction. When a chemical reaction is performed in a lab, we use the theoretical yield to calculate what the percent yield of the reaction was. Percent yield tells chemists what percent of the possible amount was actually created. Various factors affect percent yield such as reaction conditions and the skill of the chemist! Let's take a look.
