Chemical Equations and Reactions: The Chemical Reactions

The lesson covers three types of combination reactions: between two elements, between an element and a compound, and between two compounds. It highlights the benefits of chemical reactions, such as energy production and industrial applications, and the environmental harm they can cause, like pollution. The lesson concludes with the representation of chemical reactions through equations, detailing reactants, products, and conditions.
