What are the 3 steps of you use in
STOICHIOMETRY???
HINT: you did this yesterday…
Step 1: Convert given information
to moles…
Step 2: Figure out the coefficient
ratio
Step 3: Convert to what you are
looking for
Don’t forget to balance the
chemical equation and identify the
knowns and unknowns.

AND NOW A DISASTER OF CHEMICAL PROPORTIONS!!!
GET READY TO BE A COOKIE CHEMIST
Just don’t do experiments on this guy’s cookie…
Limiting ReactantThe reactant that determines, or LIMITS, the quantity of product that can be formed over the course of a reaction.
The reaction will stop when all of the limiting reactant is consumed.
Limiting Reactant – an extension on stoich
How do we find it?Think about how you completed the cookie investigation
We have to do stoichiometry MORE THAN ONCE and determine which reactant will produce LESS product. That will be the limiting reactant.
Please give me $10 if you are ready to practice!!!
Practice Problems1) Hg + S HgS
48.6g 3.6g ? G
2) C4H10 + O2 CO2 + H2O 215g 75.0g ? g
