  1. 4. - P1V1 = P2V2 helps determine how the ______ of a gas changes when its pressure changes as two variables are held constant.
  2. 6. - relates to the orientation of the orbital in space. For a given value of l, the _______ quantum number can have integral values ranging from -l to l, including 0
  3. 7. - The conditions of 273 K (0 °C) & 1 atm are known as
  4. 9. - The amount of heat transferred between the system and the surroundings is measured experimentally by
  5. 10. - Volume is directly proportional to the _______ when pressure and moles of gas are held constant
  6. 14. - Heat flows from surroundings into the system, the temperature of the beaker & surrounding air-drops is an example of what type of rxn.
  7. 16. - Heat flows from the system into surroundings, the temperature of the water & surrounding air increases is an example of what type of rxn.

  1. 1. - Enthalpy of ______ (∆Hf) of a substance is the enthalpy change for the reaction in which the substance is formed from its constituent elements.
  2. 2. - ∆H°, is the ______ enthalpy change when all reactants & products are in their ______ states.
  3. 3. - The letter l denotes the angular momentum quantum number. Indicated by the letters s, p, d, f, and so on, corresponding to the values of 0, 1, 2, 3. Defines the shape of the ______.
  4. 5. - functiondepends only on the present state of the system, not on the path the system took to reach that state.
  5. 8. - solution is the number of moles of solute per liter of solution
  6. 11. Energy - the sum of potential energy and kinetic energy of that system. The change in this term can occur in two ways: heat transfer & work bring done by or on the system.
  7. 12. - q denotes the heat _______ into or out of a system
  8. 13. - The process of adding solvent to the solution decreases the concentration of the solute without changing the number of moles of solute in the solution is known as
  9. 15. - ________ quantum number (n) relates most directly to the size and energy of the orbital indicated by the integers 1, 2, 3, etc.
  10. 17. - is the heat energy that is being absorbed or evolved by a system during the progression of a chemical reaction. The change in this term indicates whether a particular rxn is endothermic or exothermic.
  11. 18. - ∆Hf °, of a substance, is the change in enthalpy for the reaction that forms one _____ of the substance from its elements in their standard states.
