  1. Decomposition By Will and Katelyn

  2. Decomposition • In a decomposition reaction, a single compound is broken down into two or more particles.

  3. How Decomposition Reactions Occur • Decomposition Reactions always involve an exchange of energy, which is classified as either endothermic or exothermic. • In an endothermic reaction, energy is absorbed and usually caused by heat or electricity. • An exothermic reaction is a release of energy, usually combustion.

  5. How to Write Equations for Decomposition Reactions • Find the correct formula for the compound water 2H2O • Separate the elements (and compounds if any!): 2H2O  2H2 + O2 *Watch out for HONClBrF!* 3. Balance the equation (if needed)
