41 observing chemical change worksheet answers

Chemical Reactions The changes that occur during a chemical reaction are represented by a chemical equation. An equation uses chemical symbols to represent the substances that change. The reactants, on the left side of the equation, are the substances that react. The products, on the right side of the equation, 3. During chemical reactions, the oxidation state of atoms can change. This occurs when compounds gain or lose electrons, or when the bonds to an atom change.
