Types of Reactions

For the final lesson of chapter 13, students learned to classify the types of reactions as combination, decomposition, single exchange, or double exchange reactions.

  • Combination: A + B -> C
  • Decomposition: A -> B + C
  • Single Exchange: AB + C -> A + BC
  • Double Exchange: AB + CD -> AD + CD

We focused primarily slide 8 of the Lesson 73 PowerPoint.  Students are encouraged to review the full slide deck, including the vocabulary defined on slides 9-12.  Students then received the Lesson 73 Worksheet and Toxic Reaction Cards to work on for the remainder of class.  As an alternative, students who self-assessed as needing additional practice balancing equations were offered the opportunity to work through the Balancing Equations Gizmo.
