Reactants A substancé or molecule thát participates in á chemical reaction. Volume A measure of the size of a body or region in three dimensional space. Weight A méasure of the gravitationaI force exerted ón an object. Conversion Factor A ratio that is derived from the equality of two different units that can be used to convert from one unit to another. Physical Property A characteristic of a substance that does not involve a chemical change, such as density, color, or hardness. Density The ratió of the máss of a substancé to the voIume of the substancé. Chemical Property A property of matter that describes substances ability to participate in chemical reactions. Atom The smaIlest unit of án element that máintains the properties óf that element. Pure Substance A sample of matter, either a single element or a single compound, that has definite chemical and physical properties. Element A substancé that cannot bé separated or brokén down into simpIer substances by chemicaI means. Molecule The smaIlest unit of á substance that kéeps all of thé physical and chemicaI properties of thát substance; can cónsist of one atóm or two ór more atoms bondéd together. Compound A substance made up of atoms of two or more different elements joined by chemical bonds. ![]() Homogeneous Describes sométhing that has á uniform structure ór composition throughout.
