Reactants Products and Leftovers

The simulation can be used to:

*Relate the real-world example of making sandwiches to chemical reactions.

*Describe what limiting reactant means using examples of sandwiches and chemicals at a particle level.

*Identify the limiting reactant in a chemical reaction.

*Explain the Law of Conservation of Particles using examples of sandwiches and chemical reaction.

*Predict the amounts of products and leftovers after reaction using the concept of limiting reactant.

*Predict the initial amounts of reactants given the amount of products and leftovers using the concept of limiting reactant.

*Translate from symbolic (chemical formula) to molecular (pictorial) representations of matter.

The simulation is designed to give students a conceptual understanding of limiting reactants, rather than practice at solving algorithmic problems that require mass/mole conversions.
