Schulte, Northern State University, Aberdeen, South Dakota email: schul669@wolves.northern.edu |
| Subject Area: | Chemistry |
| Topic: | Balancing equations and solving gram to mole ratios |
| Grade Level: | Grade 9-12 |
| Time Frame: | 3-50 minute periods |
| Lesson Summary: | Students will learn the steps for balancing an equation. Students will then use the balanced equation in problem solving for gram to mole equations. |
| Prerequisites: | Students must understand the periodic table and elements. Also Students must have the understanding of ratios and multiplication. |
| Standards: |
9-12.P.1.4. Students are able to balance chemical equations by applying the Law of Conservation of Matter. • Trace number of particles in diagrams and pictures of balanced equations. Example: Write out an equation with symbols: Mg + 2HCl → MgCl2 + 2H2 |
| Lesson Objectives: |
The Students will learn: - how chemical reactions work and how they are set up - how to balance simple and complex reactions - how to solve complex equations based on the balanced equations Essential questions the students should be able to answer: - What elements to start with when balancing an equation. - What is a mole? - How do you use the balanced reaction to find grams and moles? |
