S’mores a delicious snack yet, a snack that can be used to showcase chemistry principles. One of the principles that can be showed is limiting and excess reactant.

The objective of the lab was to make s’mores while calculating the limiting and excess reactant within the ingredient we had: chocolate bars, cracker, and marshmallow.
