S - Limiting Reactants (Lesson)
Limiting Reactants
Introduction
Imagine that you would like to grill hotdogs for dinner. You have 12 hotdogs and 7 buns. How many hot dogs can you make? Assuming that the hot dogs and buns combine in a 1:1 ratio, you can make 7 hot dogs. The number of hot dogs that you are able to make is limited by the buns. Similarly, chemical reactions may be limited by certain reactants involved in the reaction. We call these limiting reactants. In this lesson you will learn to perform calculations to determine the limiting reactants and excess reactants in chemical reactions.
