Lesson overview:Indicators of a Chemical Reaction

  • Describe evidence for a chemical reaction
  • Apply conservation of mass to simple chemical change
  • Explain why, in terms of particles, mass stays the same in a reaction

This lesson explores what happens in a chemical reaction, ways in which we can identify that a chemical reaction has taken place and how the law of the conservation of mass applies to chemical reactions.
