Balancing Equations, Limiting Reactant, Stoichiometry, Dimensional Analysis, Mole Concept, Measurements | High School
Activity: S'more Stoichiometry
In this activity, students determine the number of graham crackers and chocolate pieces required to complete a “reaction” with a given quantity of marshmallows (the limiting reactant). They then use the same thought process with a problem involving a real chemical reaction.
-
Chemical Change, Limiting Reactant, Classification of Reactions, Percent Yield, Stoichiometry, Concentration, Molarity, Mole Concept, Dimensional Analysis | High School
Demonstration: First Day Review
In this demonstration, students see evidence of a chemical reaction.
-
Limiting Reactant, Concentration, Net Ionic Equation, Stoichiometry, Balancing Equations, Precipitate, Mole Concept, Dimensional Analysis | High School
Lab: Finding CO2 Mass in your Breath
In this lab, students will measure how much carbon dioxide they exhale by reacting their exhaled breath with limewater (calcium hydroxide solution). Students will practice writing balanced equations and completing mass-to-mass stoichiometric calculations.
-
Percent Yield, Limiting Reactant, Stoichiometry, Dimensional Analysis | High School
Activity: Cookie Stoichiometry
In this activity, students use a chocolate chip cookie recipe to answer questions related to stoichiometry, percent yield, and limiting reactants.
-
Limiting Reactant, Acid Base Reactions, Stoichiometry, Indicators, pH, Dimensional Analysis, Mole Concept, Measurements, Concentration, Molarity | High School
Lab: Acid/Base Stoichiometry
In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.
-
Titrations, Limiting Reactant, Acid Base Reactions, Indicators, Chemical Change, Equivalence Point, Stoichiometry, Balancing Equations, Chemical Change, Graphing, Error Analysis, Chemical Change, Error Analysis, Measurements, Concentration, Molarity | High School
Lab: Acid-Base Mole Ratio
In this lab, students study several concepts, including acid-base reactions, limiting reactants, and stoichiometry, by observing the contained reaction of acetic acid (diluted vinegar) with sodium hydrogen carbonate (baking soda) in an unconventional, cost effective titration.
-
Limiting Reactant, Classification of Reactions, Stoichiometry, Balancing Equations, Error Analysis | High School
Lab: Mole Relationships in a Single Displacement Reaction
In this lab, students will carry out a reaction between metallic copper and an aqueous solution of silver nitrate to determine the mole ratio between the reactants and the products and write a balanced equation based on the data.
-
Indicators, Le Châtelier's Principle, Acid Base Reactions, Chemical Change, Chemical Change, Limiting Reactant, Reaction Rate, Observations, Chemical Change | High School
Demonstration: Milk of Magnesia Magic
In this demonstration, students will observe a color change in a milk of magnesia solution as vinegar is added.
