Name ___________________________ Date _________________ Lab Station ______ Sign-Off ______ Group Members _______________________________________________________________________ S’more Stoichiometry Introduction : The building of s’mores is using the same process of stoichiometry as in any chemical reaction. The amount of ingredients determines how many s’mores can be made. The amount of the limiting reactant determines how many s’mores or the amount of product that you can make. It’s like 10 hot dogs but only eight hot dog buns! What is up with that? The limiting reactant (reagent) is the reactant that ___________ the amounts of the other reactants that can combine – and the amount of product that can form – in a chemical reaction (the reactant that runs out __________). The reaction will stop once the limiting reactant is used up. The _____________ reactant in a chemical reaction is the substance that is _______ used up completely in a chemical reaction (the reactant that you have leftovers of). Example: For the reaction: ___ K + ___ O 2 ___ K 2 O; if 0.50 g of K are allowed to react with 0.10 g of O 2 , what is the limiting reagent, and what is the reactant in excess? The following are the symbols you will use for your ingredients: Gc = Graham Crackers Cs = Chocolate squares Mm = Marshmallows Sm = S’more The following ingredients are needed to make one s’more: 2 Graham Crackers 3 Squares of chocolate 1 Marshmallow The balanced equation to make 1 smore is as follows: 2 Gc + 3 Cs + 1 Mm 1 Gc 2 Cs 3 Mm Data : Bag # __________ Number of Graham Crackers = ___________ # of S’mores = ___________ Number of Marshmallows = ____________ # of S’mores = ___________ Number of chocolate pieces = ___________
