Unit 4, Lesson 26

Reactants hardly ever combine in the ratios that we see them in in chemical reactions. It's almost like the textbook writers made up problems for students to solve! Haha, fancy that. No, back to serious business, ususually there's more of one reactant than is required to burn up the other. Because of this, chemical reactions can be short-lived. The amounts of products depends on how much reactant is present. You can only have as much product as your limiting reactant will allow. The amount of product that a limiting reactant comes up with is called the % yield.
