Understanding the Basics of Stoichiometry
What Is Stoichiometry?
Stoichiometry involves calculating the ratios of reactants and products involved in chemical reactions. It enables chemists to predict how much of each substance is needed or produced in a reaction. The core idea revolves around the mole concept, which relates quantities of substances in terms of their molar masses.
Why Is Stoichiometry Important?
- It helps in determining the correct amounts of reactants to use in a chemical process.
- It allows for the prediction of yields and product quantities.
- It aids in understanding reaction efficiencies and limiting reactants.
- It is critical for scaling laboratory reactions to industrial production.

Key Concepts in Gizmo Stoichiometry Activities
Balancing Chemical Equations
Before performing stoichiometric calculations, equations must be balanced to ensure the conservation of mass. Gizmos often include exercises that teach students how to balance equations correctly.
Calculating Moles and Molar Masses
Understanding how to convert between mass, moles, and molecules is fundamental. Gizmo activities typically involve calculating molar masses and converting quantities accordingly.
Using Mole Ratios
The mole ratio derived from the balanced equation is used to convert between different substances in the reaction. This is the core of stoichiometric calculations.
Determining Limiting Reactants
Gizmos often include scenarios where students identify the limiting reactant, which determines the maximum amount of product that can be formed.
Calculating Theoretical and Actual Yields
Students learn to compute the maximum possible yield (theoretical yield) and compare it with actual yields from experiments, understanding concepts of efficiency and percent yield.
