Reactants vs. products quick check
WebJul 22, 2024 · In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can’t change one element into another in a chemical reaction — that happens in nuclear reactions. Instead, you create a new substance with chemical reactions. WebNov 1, 2012 · Reactants are substances that start a chemical reaction, and products are substances that are produced in the reaction. A chemical reaction can be represented by the general chemical equation: Reactants → Products Bonds …
