3.3 Balancing Chemical Equations Phet Simulation

Open the balancing phet simulation to complete this activity.  CLICK ON INTRODUCTION

1

Use the simulation to adjust the coefficients and balance the following equation. Select the balance scales and bar charts to help under Tools to help.

Fill in the proper coefficients when you are successful (yellow smiley face).
N2 + H2 → NH3

1

Draw the particle view of the balanced equation as shown in the simulation.

1

Describe the purpose of the balance scales and bar charts in the simulation.

1

In order for a chemical equation to be properly balanced, what must be true?

Select All that are true

1

Click on "Separate Water" ato the bottom. Balance the reaction. What are the correct coefficients?

1

Explain in your own words how you got the coefficients for question 5.

1

Click on "Combust Methane" at the bottom. Balance the reaction. What are the correct coefficients?

1

Explain in your own words how you got the coefficients for question 7.

1

The number placed in front of a formula is called a coefficient. The small number within a chemical formula is called a subscript. Why do we adjust coefficients when balancing chemical equations and not subscripts?

1

Now click on "Game" at the very bottom of the screen. Choose at least 1 level of the game. (fyi: level 1 is kinda hard)

Click on Show your Work and record at least 3 balanced chemical equations with coefficients.

(Note: You will want to try these on paper too if it helps you balance. You'll need to know how to get the coefficients for your quiz.)
