Chemical Reactions and Their Components

The video tutorial explains the difference between reactants and products in a chemical reaction. It begins with an introduction to the concept, followed by a demonstration of a reaction between aluminum and hydrochloric acid. As the reaction progresses, products are formed, evidenced by the appearance of H2 gas bubbles. The tutorial highlights the irreversible nature of the reaction, where reactants are completely transformed into products. The video concludes with a summary of the key differences between reactants and products.

What are the initial substances called in a chemical reaction?

• Products

• Reactants
