During chemical reactions
WebFeb 15, 2024 · A chemical reaction is often accompanied by a temperature change, bubbles, color change, and/or precipitate formation. Chemical Reactions and Chemical Equations The atoms and molecules that interact are called the reactants. The atoms and molecules produced by the reaction are called products. WebMar 25, 2024 · The rate or speed at which the reactants combine is high, in part because of the nature of the chemical reaction itself and in part because more energy is generated than can escape into the surrounding medium, with the result that the temperature of the reactants is raised to accelerate the reaction even more.
