Chemical Reactions and Balancing Chemical Equations

1. Chemical Reactions and Balancing Chemical Equations

In this lesson, you'll learn how to balance a chemical reaction equation using the conservation of matter law. You'll also learn how to write both word and formula equations, what the subscripts after a letter mean and what the numbers in front of compounds mean.

Mole-to-Mole Ratios and Calculations of a Chemical Equation

2. Mole-to-Mole Ratios and Calculations of a Chemical Equation

Learn what a mole ratio is and how to determine and write the mole ratio relating two substances in a chemical equation in this video lesson. Also, learn to make mole-to-mole calculations and solve problems involving moles of substances.

Mass-to-Mass Stoichiometric Calculations

3. Mass-to-Mass Stoichiometric Calculations

Learn how to set up and make mole to mass, mass to mole and mass to mass stoichiometric calculations. Learn how the ratios of moles helps you compare and make calculations. Learn how to relate mole ratios to molar mass.

Stoichiometry: Calculating Relative Quantities in a Gas or Solution

4. Stoichiometry: Calculating Relative Quantities in a Gas or Solution

In this lesson, learn about molar volume and how to set up and make stoichiometric calculations with gases. Then learn about solution stoichiometry and how to make stoichiometric calculations with solutions.

Hydrates: Determining the Chemical Formula From Empirical Data

5. Hydrates: Determining the Chemical Formula From Empirical Data

Learn the definition of a hydrate and an anhydrate in this lesson. Discover how, when given experimental data, you can determine the formula of a hydrate by following simple steps that include finding the moles of hydrate and anhydrate and comparing the two to write the formula.
