Limiting Reactant Problems Notes
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:
2 H2 + 1 O2 -> 2 H2O1
Using equation above, if I react 3 moles of O2 with 5 moles of H2 which will be the limiting reactant?
___ Ca1Br2 + ____ Na3P1 ==> ____ Ca3P2 + ____ Na1Br1
Using the balanced equation above, if I react 6 moles of Ca1Br2 with 5 moles of Na3P1, which reactant will be the limiting reactant.
