Across
- 2. Complex the structure that results in the maximum energy point along the reaction path
- 4. a substance obtained from another substance through chemical change
- 9. a substance that speeds up a chemical reaction, but is not consumed by the reaction; hence a catalyst can be recovered chemically unchanged at the end of the reaction it has been used to speed up
- 10. thermodynamic function that describes the randomness and disorder of molecules based on the number of different arrangements available to them in a given system or reaction
- 12. Chatelier's Principle if the equilibrium of a system is disturbed by a change in one or more of the determining factors (as temperature, pressure, or concentration) the system tends to adjust itself to a new equilibrium by counteracting as far as possible the effect of the change
- 14. is the ratio of solute in a solution to either solvent or total solution
- 15. a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent. It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium
- 18. he loss of electrons during a reaction by a molecule, atom or ion
- 19. a solution that can resist pH change upon the addition of an acidic or basic components
- 20. when two or more chemicals combine and form a more complex product
- 22. a force exerted by the substance per unit area on another substance
Down
- 1. any substance that undergoes a chemical change in a given reaction
- 2. Energy the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction
- 3. a chemical reaction that occurs between a fuel and an oxidizing agent that produces energy, usually in the form of heat and light It is also known as burning
- 5. is the property of matter which reflects the quantity of energy of motion of the component particles
- 6. Chemical Reaction Reversible reactions will reach an equilibrium point where the concentrations of the reactants and products will no longer change
- 7. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time
- 8. Electron outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair
- 11. a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds
- 13. It is the sum of the internal energy added to the product of the pressure and volume of the system
- 16. Replacement Reaction a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound
- 17. a substance that decreases the rate of, or prevents, a chemical reaction
- 21. Area how much exposed area a solid object has, expressed in square units
