When do you need to worry about it? 
 
Answer: 
 
 
Limiting Reactant (also called Limiting Reagent): 
In excess reactant: 
 
 
Why do we need to know which reactant is Limiting? Answer: 
 
 
Example #1: 
 
<center> 2 H2&nbsp;&nbsp;+&nbsp;&nbsp;1 O2&nbsp;&nbsp;->&nbsp;2 H2O1</center> 
 
Using equation above, if I react 3 moles of O2 with 5 moles of H2 which will be the limiting reactant? 
 
 
 
 
 
Example #2: 
 
<center> ___ Ca1Br2 + ____ Na3P1 ==> ____ Ca3P2 + ____ Na1Br1</center> 
 
Using the balanced equation above, if I react 6 moles of Ca1Br2 with 5 moles of Na3P1, which reactant will be the limiting reactant.
