Student Exploration: Limiting Reactants
Directions: Follow the instructions to go through the simulation. Respond to the questions and
prompts in the orange boxes.
Vocabulary: chemical equation, chemical formula, chemical reaction, coefficient, limiting reactant, molecule,
product, reactant, subscript
Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
Imagine you and your friends are making hot dogs. A complete hot dog consists of a wiener and a bun. At the
store, you buy four packages of eight wieners and three bags of 10 buns.
1. How many total hot dogs can you make?
30 hotdogs
2. Which ingredient limited the number of hot dogs you could make?
the buns
3. Which ingredient will you have leftovers of?
the hotdogs
Gizmo Warm-up
Just as ingredients can be put together to make a new food, substances can combine
during a chemical reaction to produce new substances. The substances that
undergo change are called reactants. The new substances are products.
Sometimes during a chemical reaction, one type of reactant will be used up before the
other reactants. This reactant is the limiting reactant. Using the Limiting Reactants
Gizmo, you can determine which reactant is limiting in various scenarios.
To begin, make sure H2 + O2 becomes H2O is selected. The small “2” in H2, O2, and
H2O is a subscript. Subscripts represent the number of atoms in a molecule.
1. Use the sliders to set the number of O2 molecules and H2 molecules to two.
A. How many hydrogen molecules (H2) are there? 2 Hydrogen atoms? 4
B. How many oxygen molecules (O2) are there? 2 Oxygen atoms? 4
2. How many H2O molecules do you think will form when these four molecules react? 2
3. Click Play ( ). How many H2O molecules actually formed? 2
