Across
  1. 5. - The amount of heat transferred between the system and the surroundings is measured experimentally by
  2. 6. function - depends only on the present state of the system, not on the path the system took to reach that state.
  3. 9. - 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
  4. 10. - 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
  5. 13. - ________ quantum number (n) relates most directly to the size and energy of the orbital indicated by the integers 1, 2, 3, etc.
  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. - Enthalpy of ______ (∆Hf) of a substance is the enthalpy change for the reaction in which the substance is formed from its constituent elements.
  8. 17. - q denotes the heat _______ into or out of a system
  9. 18. - solution is the number of moles of solute per liter of solution

  1. 1. changes as two variables are held constant.
  2. 2. - P1V1 = P2V2 helps determine how the ______ of a gas changes when its
  3. 3. - ∆H°, is the ______ enthalpy change when all reactants & products are in their ______ states.
  4. 4. - Heat flows from the system into surroundings, the temperature of the water & surrounding air increases is an example of what type of rxn.
  5. 7. - 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.
  6. 8. - The conditions of 273 K (0 °C) & 1 atm are known as
  7. 11. - Volume is directly proportional to the _______ when pressure and moles of gas are held constant
  8. 12. - ∆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.
  9. 15. 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.
