Chemical-any substance that has a defined composition
Chemical reaction- the process by which one or more substances change to produce one or more different substances
States of matter-the physical forms of matters, which are solid, liquid, gas, and plasma 
Reactant- a substance or molecule that participates in a chemical reaction  Product- a substance that forms in a chemical reaction
Matter-anything that has mass and takes up space
Volume-a measure of the size of a body or region in three-dimensional space
Mass-a measure of the amount of matter in an object; a fundamental property of an object that is not affected by the forces that act on the object, such as the gravitational force
Weight- a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe
Quantity- something that has magnitude, size, or amount
Unit- a quantity adopted as a standard of measurement
Conversion Factor- a ration that is derived form the equality of two different units that can be used to convert from one unit to the other
Physical property- a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness
Density –the ratio of the mass of a substance to the volume of the substance; often expressed as grams per cubic centimeter for solids and liquids and as grams per liter for gases
Chemical Property- a property of matter that describes a substance’s ability to participate in chemical reactions
Atom- the smallest unit of an element that maintains the properties of that element
Pure Substance- a sample of matter, either a single element or compound, that has definite chemical and physical properties
Element- a substance that cannot be separated or broken down into simpler substances by chemical means’ all atoms of an element have the same atomic number
Molecule- the smallest unit of a substance that keeps all of the physical and chemical properties of that substance; it can consist of one atom or two or more atoms bonded together
Compound- a substance made up of atoms of two or more different elements joined by chemical bonds
Mixture- a combination of two or more substances that are not chemically combined
Homogeneous- describes something that has a uniform structure or composition throughout
