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?
