Unit 4 · Chemical Reactions

Chapter 4.1

Writing What Happened: Evidence, Balanced Equations, and Net Ionic Equations

Mix two clear solutions and a white solid appears from nowhere. Nothing was created; atoms only changed partners, and a balanced equation is the receipt that proves it.

in preparation · lesson 15 of 45

By the end

  1. 01Recognize evidence of a chemical change and distinguish it from a physical change
  2. 02Write a balanced equation that conserves atoms and charge for a chemical or physical process
  3. 03Write molecular, complete ionic, and net ionic equations and choose the right one
  4. 04Translate a balanced equation into a particulate diagram and back
