  1. 1. _______reaction: a process in which one or more substances, the reactants, are converted to one or more different substances
  2. 5. The chemicals that are present before a chemical reaction takes place. They react together to produce new chemical compounds
  3. 7. Water, made up of water
  4. 11. A reaction in which a compound is broken down into simpler compounds or elements
  5. 13. a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy
  6. 14. ________Replacement: Also known as a metathesis reaction. A reaction in which two reactants trade partners
  7. 15. ______equation: Method of writing the essential features of a chemical reaction using chemical symbol
  8. 16. ________ series: an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest.
  9. 18. ________Replacement: A reaction in which one component of a compound is replaced by a new component
  10. 20. an element that doesn't have the characteristics of metal
  11. 21. any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light

  1. 2. any substance composed of identical molecules consisting of atoms of two or more chemical elements
  2. 3. Equations: A description of a chemical reaction that gives the chemical formulas of the reactants and the products of the reaction
  3. 4. one of the three principal states of matter, whose most obvious physical properties is retention of volume and its conformation to the shape of its container
  4. 6. A molecule that is produced in a chemical reaction
  5. 8. the construction of complex chemical compounds from simpler ones
  6. 9. made up of two or more atoms that are chemically bonded together
  7. 10. A substance that speeds up a chemical reaction without participating in it either as a reactant or product. Catalysts are thus not consumed in the reaction
  8. 12. one of the three basic states of matter, forms from liquid or gas because the energy of atoms decreases when the atoms take up a relatively ordered structure
  9. 13. A number used to indicate the presence of more than one unit of a chemical species in a chemical equation
  10. 17. a substance whose atoms all have the same number of protons
  11. 19. one of the three fundamental states of matter that appears to have no structure at all
