Key Terms
Reactants: The substances that undergo a chemicalchange in a reaction.
Products: The new substances that are formed as a result of a chemical reaction.
Chemical Equation: A representation of a chemical reaction using chemical formulas and symbols.
Endothermic Reaction: A reaction that absorbs heat from its surroundings.
Exothermic Reaction: A reaction that releases heat to its surroundings.
Understanding chemical reactions is essential in comprehending many natural processes and human-made products. By grasping the key concepts and types of chemical reactions, you can appreciate the transformations that occur in the world around you.
