There are many differences between reactants and products. A reactant is the process of one chemical substance turning into another chemical substance. They are broken down during reactions and used up over time as the reaction progresses.This process is very important to daily life.
Examples of reactants include burning fuel to provide energy for vehicles, as well as water evaporating, which products rain. Products are the result of a reaant. Though they work together to create reactions, reactants is the start of the reaction and products are what are produced from the reaction. The formula of a chemical reaction is Reactants -> Products.
