Understanding Chemical Reactions: Fizz, Hydrogen, and Acid-Base Interactions

This lesson covers essential chemistry concepts including the release of carbon dioxide when acids react with limestone and the formation of hydrogen when acids react with metals. Students will learn to define reactants and products, and understand how heat and electricity can decompose substances. Additionally, this lesson will demonstrate tests for hydrogen and carbon dioxide, further emphasizing their properties. Enjoy engaging activities around acid-base reactions, including practical experiments and safety measures for working with chemicals.
