1) A product in chemistry refers to the substance or substances that result from a chemical reaction. It is what is formed when reactants -- the starting materials in a chemical process -- react and undergo a transformation. In a chemical equation, products are typically shown on the right side, indicating what is produced after the reaction has taken place.
For example, in the reaction to create water (2H2 + O2 → 2H2O), 2H2O (water) is the product, illustrating the outcome of combining hydrogen and oxygen gases. Products are essential for understanding the purpose and outcome of chemical reactions, affecting various fields such as medicine, manufacturing, and environmental science.
