  1. 3. A process in which more energy is released than is required to break bonds in the initial reactants of a chemical reaction.
  2. 4. The relative number of moles of the substances required to produce a given amount of product in a chemical reaction.
  3. 8. A representation of a chemical reaction in which the reactants and products are expressed as formulas.
  4. 10. a reaction in which the ions of two compounds exchange places in an aqueous solution to form two new compounds; AX+BY→AY+BX
  5. 13. A reaction in which a substance reacts rapidly with oxygen, often producing heat and light as well as CO₂ and H₂O.
  6. 15. The original substances in a chemical reaction.
  7. 16. a reaction in which a single compound breaks down to form two or more simpler substances.
  8. 17. A substance that speeds a chemical reaction by lowering the activation energy of the reaction.
  9. 18. The energy stored within the bonds of different substances.

  1. 1. A substance that is formed by a chemical reaction.
  2. 2. A reaction when one reactant loses electrons, and another reactant gains them.
  3. 5. A reaction in which two or more substances react to form a single substance.
  4. 6. The reactant in an enzyme-catalyzed reaction; what the enzyme causes to react.
  5. 7. a reaction in which one element or radical takes the place of another element or radical in a compound.
  6. 9. radical an atom or group of atoms with an unpaired electron.
  7. 11. a biological molecule that acts as a catalyst; most commonly a protein but there are also RNA catalysts.
  8. 12. The state in which the rates of the forward and reverse chemical reactions are equal.
  9. 14. A reaction that requires more energy to be started.
