  1. 2. another name for network solid
  2. 3. an insoluble solid that forms in a precipitation reaction when two or more aqueous solutionsare mixed
  3. 7. the process by which either the molecules of a covalent compound or the cations and anions bound in the lattice of an ionic compound break up into individual cations and anions
  4. 10. a reaction in which two reactants AB and CD react to form products AD and BC
  5. 12. a substance that increases the concentration of OH- ions in an aqueous solution
  6. 13. the temperature at which a pure substance changes from a liquid to a gas at standard atmospheric pressure. Because condensation is the reverse of evaporation, the boiling point is numerically equal to the condensation point
  7. 15. bonds between metal atoms that are the result of electrons being shared by all atoms
  8. 18. the work of planning, performing, and perfecting the preparation of a chemical compound
  9. 19. a substance produced in the course of a chemical reaction by the transformation of one or more reactants
  10. 20. the relatively weak intermolecular attractive forces exerted by molecules on each other, caused by brief, constantly shifting electron imbalances in the molecles that cause them to act as momentary dipoles
  11. 22. a starting material for a chemical reaction; a substance that enters into the reaction and is tranformed into one or more product substances
  12. 24. a substance that increases the concentration of H+ ions in an aqueous solution
  13. 25. a reaction in which one element replaces another element in a compound
  14. 26. the reaction of any substance with oxygen (O2)
  15. 28. any solid that doesn't consist of discrete molecules
  16. 30. a change from the liquid phase to the gas phase
  17. 31. the reaction between an H3O+ ion supplied by an acid and an OH- ion supplied by a base. A hydronium ion and a hydroxide ion react with each other to give two molecules of water
  18. 32. an equation that shows the reactants and products of the reaction, but not the spectator ions

  1. 1. a chemical reaction in which all reactants are gases
  2. 4. a reaction in which an insoluble solid (the precipitate) forms when two or more aqueous solutions are mixed
  3. 5. another name for London force
  4. 6. a reaction in which two or more substances combine to give another substance
  5. 8. either the liquid or the solid phase of matter
  6. 9. the temperature at which a substance changes from a liquid to solid at standard atmospheric pressure. Because melting is the reverse of freezing, the freezing point is numerically equal to the melting point
  7. 11. an equation that shows all the ions, bth those that take part in the reaction and the spectator ions
  8. 14. an ion present in the vessel in which a chemical reaction takes place that does not take part in the reaction
  9. 16. a nonmolecular solid made up of atoms held together by covalent bonds
  10. 17. a notation for showing what takes place in a chemical reaction. Th chemical formulas of all reactants are written on the left side of the arrow, and thee chemical formulas of the products are written on the right side
  11. 21. a reaction in which a compound breaks down(decompose) into two or more simpler compounds or substances
  12. 23. a process in which two or more reactants are transformed into one or more products through the breaking of chemical bonds in the reactant mmolecules and the formation of new cemical bonds in the product molecules
  13. 27. an intermolecular dipole-dipole attraction between a δ+ H atom covalently bonded to either an O, N, or F atom in one molecule and an O, N, or F atom in another molecule
  14. 29. a change from the gas phase to the liquid phase
