    Here are the Flashcards -- remember the first column is the question and the second column is the answer, so fold it in half. It is an Excel file. RedicanChemflash.xlsx

    The EXAM Schedule:
1/16 Saturday Academy - study help 10am-2pm
1/19  LAB exam - testing an unknown
1/20 Written Portion - problem solving and drawing atoms, etc
1/21 Multiple Choice Portion - like the homeworks
Good luck studying, 
Study a little each day -- NO CRAMMING.
Study the flashcards, play old review games (click on chemistry is cool), go to webassign and take the Practice Tests, or study chemistry regents questions online or from a Regents Study guide.
Do your best, and you will be satisfied -- Ms Redican :)

What is osmotic pressure?$0      NOTES: $0 1 Colligative Properties depend on the AMOUNT OF SOLUTE added to the Solvent.  The more solute you add, the more the property changes.$0 2 BEFORE WE GET TO TODAY's Colligative property, you need to know what regular Vapor Pressure is : At the surface of every liquid the molecules are evaporating into a vapor (gas) -- this gas then can condense back into the liquid.  So at the surface of a liquid you have a Dynamic Equilibrium where there is the liquid surface and vapor (gas) above it.  The pressure of the gas at the surface of the liquid is the VAPOR PRESSURE.$0 What is Vapor Pressure?  click and watch this video.$0 $0 3 Colligative Property: Vapor Pressure Reduction$0 When you add more solute to a solvent, less of the solvent  can turn into$0 a gas, the solute blocks the solvent from turning into a vapor.  SO, less Vapor is above the liquid and the Vapor Pressure is Reduced.$0 $0 Online Lab : Copy these Directions first: $0 Procedure:$0 Choose water as the solvent, choose temperature 25 C, choose salt as the solute.  Then, do the data for $0 Solvent         Solute          Vapor Pressure$0  50 g              0 g                _______$0  50 g              5 g                _______$0  50 g             10 g               _______ $0  50 g             20 g               _______$0  50 g             40 g               _______$0 What happens to the Vapor Pressure , as more solute is added ?$0 $0 Now do the lab by clicking on it $0 Vapor Pressure Lab online $0 $0 4) Next  remember living environment and osmosis -- $0Osmotic pressure is the pressure that must be applied to a solution to prevent the inward flow of water across a semipermeable membrane.$0 Do the Lab Below to understand this better.  Copy into your notes as you go along .$0 Osmotic Pressure Lab$0 $0 You are done - re-read your notes tonight.  Homework #26 will be due online by Friday night 1/15/10.$0 :) ms red$0 $0 $0 $0 $0        All homework, quizzes and tests will be completed through a new link called WebAssign click on the following to get there:  WebAssign  $0 $0     $0  If you still have not finished this past summer's assignment, then go to the website below and read and complete the introduction and the tasks and the process.  Everything is there.  Summer Chemistry WebQuest$0 $0 $0 $0If you have any questions or concerns, contact me at      tararedican1@aol.com $0 $0$0 $0Sincerely, $0 Tara Redican, MVA Chemistry Teacher$0 P.S.  To contact me simply hit the CONTACT tab above and send me an email!  $0 $0 $0 $0 $0 $0
