22 Questions

1. The loss of electrons or an increase in oxidation state by a molecule - atom - or ion

2. PH = - log[H+]

3. Oxidation -Reduction Reaction; A kind of reaction in which electrons are transferred - thereby oxidizing some atoms - and reducing others

4. The gain of electrons or a decrease in oxidation state by a molecule - atom - or ion

5. All systems tend to lose useful energy and approach a state of minimum free energy or an equilibrium state. G = H - T x S

6. Energy is conserved; dU=dQ- dW+dG

7. A process in which one substance permeates another.

8. Evaporation; The transformation of a compound from its liquid state to its gaseous state

9. A species that can accept or combine with a proton

10. The mathematical equation k=Ae^-Ea/RT - which expresses the dependence of the rate constant on temperature

11. A system in which the molar free energy of a solute in water depends on the mole fraction

12. The effective or apparent concentration - or that portion of the true mole- based concentration of a species that participates in a chemical reaction - normalized to the standard state concentration.

13. The sum of exponents of concentrations of reactants

14. PH values above 7; Prevalence of OH-

15. The maximum quantity of a substance that can dissolve in a unit volume of solvent under specified conditions

16. The minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction

17. The accumulation of gases - liquids - or solutes on the surface of a solid or liquid.

18. The ionized - or ionizable - constituents of organic matter

19. A species that can release or donate a hydrogen ion (proton)

20. The state of an element in a compound with respect to the number of electrons it has lost or gained - expressed as a positive or negative number indicating the ionic charge of an atom and equal to its valence.

21. The transformation of a compound from its solid to gaseous state

22. A thermodynamic quantity equal to the enthalpy (of a system or process) minus the product of the entropy and the absolute temperature
