Chemical Reaction | the process by which one or more substances change to produce one or more different substances |
Reactant | a substance or molecule that participates in a chemical reaction |
Product | a substance that froms 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 cahnge with the location of the object in the universe. |
Quantity | something that hs magnitude, size, or amount |
Unit | a quantity adopted as a standard of measurement |
Conversion factor | a ration that is derived from the equality of two different units and 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 cahnge, such as density, color or hardness. |
Density | the ration 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 amtter, either a single element or a single compound, that has definite chemical and physical properties. |
Element | A substance that cannot be separated or broken down into simpler substance by chemical means; all atoms of an elemetn 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 taht are not chemically combined |
Homogeneous | describes somethign that has a uniform structure or composition throughout |
heterogeneous | composed of dissimilar components |
