Reactants, Products and Leftovers

Reactants, Products and Leftovers Screenshot Download 2,012 kB
Version: 1.05 (change log)
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. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?

See Below

Teaching Resources

Main Topics

  • Chemical Reactions
  • Limiting Reactants

Sample Learning Goals

  • 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.
  • Use your own words to explain the Law of Conservation of Particles means 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.
  • Explain how subscripts and coefficients are used to solve limiting reactant problems.
