Directions:

  1. Use Reactants, Products, and Leftovershttps://phet.colorado.edu/en/simulation/reactants-products-and-leftovers simulation to create your own sandwiches and then see how many sandwiches you can make with different amounts of ingredients. Start off in the sandwich section (select the giant sandwich).

Test your learning:

  1. a. Predict (without using the sim) how many cheese sandwiches, as defined by the picture to the right, you can make if you have 6 pieces of
  2. bread and 4 slices of cheese.

4. Why did the number of sandwiches change even though the amounts of
ingredients were the same? Research what “limiting reactant” means and then
write a description in your own words using the situations in #2 and #3 as
supporting evidence.
5. A tricycle factory gets a shipment with 400 seats and 600 wheels. Use your ideas
about Limiting Reactants to explain how you would figure out how many tricycles
can be made.
Switch to the Molecules simulation (at the bottom of the simulation screen).)
Relate the model to Chemistry:
6. The balanced chemical reaction for producing water is: 2 H2 + 1 02 → 2 H2O.
Predict which reactant amounts (of the three examples shown below) would get the
most water with the least amount of leftovers. Explain how your understanding of
Limiting Reactant helped you figure this out.
