# Ch 10: AP Chemistry: Stoichiometry and Chemical Equations

Watch video lessons on stoichiometry and chemical equations and learn to balance equations, calculate moles, find reactants, and more. These lessons are just a portion of our AP Chemistry course.

## AP Chemistry: Stoichiometry and Chemical Equations - Chapter Summary and Learning Objectives

Stoichiometry is a branch of chemistry that involves the quantities of reactants and products on both sides of the equations that illustrate chemical reactions. In this chapter, our instructors will show you how to make calculations using moles in combination with other known quantities to answer questions about chemical reactions. You'll learn how to calculate how much product will be produced in a reaction and what might limit that production. Our lessons are broken down into smaller topics so you can learn about these calculations individually. This chapter is designed to teach you:

• How to balance chemical equations
• How to calculate moles and masses of reactants and products
• How to identify a limiting reactant
• How to determine empirical formulas for elements in a compound

VideoObjective
Chemical Reactions and Balancing Chemical EquationsLearn what to observe when a chemical reaction takes place and how to write the equation for that reaction.
Mole-to-Mole Ratios and Calculations of a Chemical EquationUnderstand how to use moles to relate two substances in a chemical equation and calculate their numbers.
Mass-to-Mass Stoichiometric CalculationsExplore how to use masses to relate substances on both sides of a chemical equation.
Stoichiometry: Calculating Relative Quantities in a Gas or SolutionExamine the calculations involved in reactions with gases or solutions of substances.
Limiting Reactants and Calculating Excess ReactantsUnderstand how to determine which reactant limits the reaction and calculate the excess amount of that reactant.
Calculating Reaction Yield and Percentage Yield from a Limiting ReactantLearn how to use the limiting reactant to calculate the ideal reaction yield and percentage yield.
