Description

Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants.
The primary aims of the lab are:
1) Relate the real-world example of making sandwiches to chemical reactions
2) Describe what limiting reactant means using examples of sandwiches and chemicals at a particle level
3) Identify the limiting reactant in a chemical reaction
4) Use your own words to explain the Law of Conservation of Particles means using examples of sandwiches and chemical reaction
5) Predict the amounts of products and leftovers after reaction using the concept of limiting reactant
6) Predict the initial amounts of reactants given the amount of products and leftovers using the concept of limiting reactant
7) Translate from symbolic (chemical formula) to molecular (pictorial) representations of matter
8) Explain how subscripts and coefficients are used to solve limiting reactant problems.
