What you will learn in Reactions & Stoichiometry

1. 1. Balancing Equations

   Atoms are never created or destroyed — coefficients make both sides match.

2. 2. Reaction Types

   Synthesis, decomposition, displacement, and combustion — five recognizable patterns.

3. 3. The Mole Concept

   A mole is just a very large counting number — Avogadro's number of particles.

4. 4. Mole Ratios

   A balanced equation's coefficients are a ratio you can convert moles through.

5. 5. Limiting Reactants

   The reactant that runs out first caps how much product can form.

6. 6. Reaction Yield

   Theoretical yield is a ceiling; real reactions almost always fall short of it.
