States that the mass of an isolated system (closed to all matter and energy) will remain constant over time. | Law of Conservation of Mass |
Changes affecting the form of a chemical substance, but do not change the chemical composition of that substance. | Physical Change |
Occur when a substance combines with another to form a new substance. | Chemical Change |
Pure chemical substance consisting of one type of atom distinguished by its atomic number. | Element |
A way of expressing information about the atoms that constitute a particular chemical compound. | Chemical Formula |
Molecules composed only of two atoms, of either the same or different chemical elements. | Element (Diatomic) Molecule |
Made up of 2 or more elements. | Compound Molecule |
Symbolic representation of a chemical reaction where the reactant entities are given on the left hand side and the product entities on the right. | Chemical Equation |
Process that leads to the transformation of one set of chemical substances to another. | Chemical Reaction |
A substance participating in a chemical reaction, especially a directly reacting substance present at the initiation of the reaction. | Reactants |
Formed when the reactant(s) react with each other by over coming the activation energy of a chemical reaction. | Products |
Constant term related to the properties of a product. | Coefficient |
The subscript indicates the number of the preceding element. | Subscript |
Chemical compound in which ions are held together in a lattice structure by ionic bonds. | Ionic Compound |
Compound in which the atoms that are bonded share electrons rather than transfer electrons from one to the other. | Covalent Compound |
Compound that contains one or more metal elements. | Metallic Compound |
Purposeful execution of chemical reactions to get a product, or several products. | Synthesis |
Separation of a chemical compound into elements or simpler compounds. | Decomposition |
Reaction in which one element takes the place of another element in a compound. | Single Replacement |
A chemical reaction between compounds in which the elements in the reactants recombine to form two different compounds, each of the products having one element from each of the reactants. | Double Replacement |
