The Simulation

  1. Select Introduction
  2. Refresh the page if you need to start over for any reason.
  3. Notice the "Tools" menu in the upper right. Experiment with the balance and the bar graph to determine if either tools option helps you to visualize the balancing process.
  4. The three reactions you will balance are at the bottom of the screen.
  5. Use the arrows next to the compounds to change the coefficients.
  6. You must keep working until you get the smiley face above the equals sign to appear.
