1. Energy/mole

2. Electrons are free to cycle around arrangements of atoms which are alternatively single- and double- bonded to one another. These bonds may be seen as a hybrid of a single bond and a double bond - each bond in the ring identical to every other

3. The heat of reaction when water is assumed to remain in a vapor state; also called the net heat of combustion

4. For a photon to be able to cause photolysis - it must have at least as much energy as...

5. Benzene; graphite

6. Photochemical reaction; photochemical dissociation; or simply photolysis

7. Organic matter - silt - clay - sand

8. Number of protons in the nucleus

9. Wavelength
10. The number of moles of substance per liter of solution

11. Groups linked by straight or branched carbon chains

12. 6.02x10^23 molecules

13. At standard STP (corresponding to __ degrees celsius and __ atm) - 1 mole of an ideal gas occupies ___ L and contains ___ molecules.

14. 1 mole of a substance dissolved into enough water to make the mixture have a volume of 1 L.

15. The more molecules of benzene - the more hydrophilic/hydrophobic the compound

16. 1 atm and 298 K (kj/mol)

17. First balance the chemical reaction - then for each species multiply the number of moles by the standard enthalpy to find total enthalpy

18. The process of going from one phase to another

19. Change in enthalpy (H2-H1); the sum of the enthalpies of the reaction products minus the sum of the enthalpies of the reactants

20. Molecules cannot store up energy from a series of photon encounters (waiting until enough energy is accumulated to cause photolysis...

21. The heat released when water condenses to liquid form - also known as the gross heat of combustion

22. H=U+PV; H2-H1=change in H=Q

23. Inorganic

24. The sum of the atomic weight of all the constituent atoms

25. All single bonds
