Chemical properties describe how a substance behaves during a chemical reaction, like flammability or reactivity with acid. Chemical changes, on the other hand, involve the formation of new substances with different properties. Think of burning wood (chemical change), where wood transforms into ash and gases, exhibiting different chemical properties than the original wood.
Match the term with its definition:
