Chemical Reactions and Balancing Equations

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This will...

The breakdown of your breakfast and plants photosynthesizing all relate to the simple movement of electrons. Learn about the complex manner of redox reactions, where electrons move from one compound to another, changing and propelling...

Students are introduced to the process of balancing chemical equations. First, they see that a chemical equation describes the chemical reaction that takes place when two elements are combined. In chemistry, that reaction must be written...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Make the microscopic world of chemical reactions come to life. An engaging video demonstrates a methane-oxygen reaction. Learners see the reaction take place and observe the chemical equation being balanced. 

Heat things up in your high school chemistry class with a instructional video on combustion reactions. Starting off with a brief explanation of combustion and the different chemicals involved, this resource walks step by step through the...

What is more important, style or substance? This video explains the difference between physical (style) changes and chemical (substance) changes. It uses many examples and various ways of determining which type of change has occurred.
