Let's Make S'mores
Unit 10: Stoichiometry
1 graham cracker, halved
1 large marshmallow
3 squares of a Hershey's bar
What is Stoichiometry?
‘Stoichio’ means element and ‘metry’ means the process of measuring. The mass and quantity relationships among reactants and products in a reaction are found using the process of stoichiometry.
Let’s examine stoichiometry by building a chemical equation for the construction of a S’more!
2) How many boxes of graham crackers and how many chocolate bars are needed to make this many S'mores?
Check Your Work!
GIven the reaction: Cu + 2AgNO3 --> Cu(NO3)2 + 2Ag
How many grams of silver can be produced from 15 g of Cu placed in AgNO3 solution?
What is stoichiometry?
What is a limiting reactant?
What is an excess reactant?
So you don't forget your S'mores recipe...enjoy a S'mores kit!
