Lesson 12 Balancing Chemical Reactions
Completion requirements
Conclusion
Properly written and balanced chemical reaction equations are essential for future studies in chemistry.
B12.12 Chemical equation
In this lesson, you learned how to balance chemical reaction equations and how to predict products when given the reactant species.
Writing balanced chemical reaction equations requires you to recall from Section 2 how to properly write chemical formulas for compounds.
In the next lesson, you will look at how to calculate amounts of chemical substances.

- Select “Game.”
- Select “Level 1.”
- Adjust the coefficient for each reactant and product until you think the reaction is balanced (note that you need to include a 1 if required for the balancing) and then click “Check.”
- You can only check your answer twice before you will need to move on to the next equation.
- Once you have completed Level 1, move on to Level 2 and Level 3.
