Understanding Chemical Equations

In this chemical equations instructional activity, students learn to balance chemical equations by counting the number of atoms of each element in the products and reactants and making them equal. This instructional activity has 5...

Newcomers to chemistry compare hydrogen peroxide to water, realizing that the difference of one oxygen atom significantly affects the chemical properties. Other pairs of compounds and their formulas are also examined. A few chemical...

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...

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...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

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...

Start your states of matter unit off right with an engaging video! Before scholars can write and balance equations or predict products, knowledge of the three main states of matter is essential. The first in a 14-part series...

Did you know when you mix the reactants sulfur, tungsten, and silver, you get the products SWAg? The simulation begins with making sandwiches, to show pupils reactants and products of something familiar. They then can make water,...

Learn the basics of chemical reactions in this video. Understand that products and reactants can be reversible or irreversible depending on the reaction. [9:12]
