Post Lab Survey and HELP!

Below is the link for the after lab survey.  It will ask you to give the name of the lab that we did.  The official title is "How Can Color be Used to Determine the Mass Percent of Copper in Brass"  Thanks for doing the survey.  Also, if you want to earn even more extra credit, I need at least five students to complete a quick post lab assessment.  It is only one queston and involves using a Beer's Law plot to determine the concentration (molarity) of a copper solution and then using the copper ion concentration in a stoichiometry calculation.  I will give extra credit on top of the extra credit you are receiving to finish the post lab assessment.  Have a good summer if I do not see you again until next fall.

AP Chemistry Test Information for Monday, May 7th

• The AP Chemistry test begins at 8:00 a.m. on Monday, May 7th, 2012.  The test will be given in the auxiliary gym.  Be at school at 7:30 a.m.  There was some discussion in class on Friday as to what type of writing utensil could be used.  I cannot find that only pens can be used, but I do not doubt it.  Bring both.  I will have a bunch of pencils and ball point pens in my room, so you can come and borrow both from me.  Also, if you need to borrow a calculator, please come and see me.  Make sure that your batteries are good before going into the exam.  
• Please go the the Events Calendar.  All VODCast solutions for the Day 7 review packet are posted under the dates Friday, May 4th and Saturday, May 5th.
• As you review for the test, make sure that you review all of the free response problems from last week and all of the problems from the Friday morning review sessions.  Also, going over the free response problems done in class from the last two units (Thermochemistry and Electrochemistry) would be a good idea.  Everyone should have both copies of the multiple choice practice exams given.  In both packets, a partial solutions guide to 1999 has been supplied and a full solutions guide to 2002 has been supplied.  Make sure that you go through both of those tests and cover the material that you missed when taking the practice tests.
• Another good form of review is to go back and watch the old VODCasts given throughout the year.  Just page back through the months of the Events Calendar.  A total review of the gas laws can be found in November.  Also in November are the VODCasts covering the independent study in organic chemistry.  Naming of compounds, writing chemical formulas, and simple stoichiometry VODCasts are made available on the first page of the AP Chemistry webpage.  Do not work all (or any) of the problems, but if you just watch, it is a good way to refresh your memory on the concepts.
• You can also page back through the entries of the blog to look at solutions to problems that were given as a way to review past concepts.
• The format of the test is first the multiple choice section then the free response section. You will have 90 minutes to answer 75 multiple choice questions. You will only be given a periodic table for the multiple choice exam. You will need to remember basic equations and do simple calculations without the aid of a calculator. You will have a list of equations and constants for the free response section of the test. You will have two parts to the free response section. Part (A) is the part of the free response test that calculators are allowed. You will have 55 minutes for part (A). Part (B) does not allow calculators and is when you answer conceptual questions. You will have 40 minutes to finish part (B). The multiple choice part of the test is worth 50% of your overall grade and the free response is the other 50%.
• On the second part of the free response test, the reactions section of the test will be given.  Do not spend more than 10 minutes (if even that - I would shoot for 5 to 7 minutes) on that section.  Remember, you get at least one point for writing correct reactants, so do that at least.  Write only the net ionic equation.  Know the BIG FIVE solubility rules.  Anything that does not fit, assume it will be a precipitate will form.
• In all of the VODCast solutions dealing with equilibrium, I showed I.C.E tables.  If determining the equilibrium concentrations is not dependent upon it, in the interest of time, do not show them.  Do show the equation, with values, used to determine the unknown value. 
• Remember, you are not only studying for the AP Chemistry exam, but also for the final for the AP Chemistry class, which will count for 20% of your semester grade. The test will given over a total of three days. On Tuesday, May 8th, you will take the multiple choice section of the final. On the AP multiple choice test, you get roughly 50 seconds per question. The multiple choice test for the final will be designed with 46 multiple choice questions to be completed in a 55 minute time frame. Wednesday, May 9th, you will be taking the 40 minute free response section (conceptual questions, equations supplied, but no calculator). On Thursday, May 10th, we will be tie-dyeing. On Friday, May 11th, the calculator portion of the free response part of the test will be given. You normally have 55 minutes for this part of the exam, but will only be given 50 minutes. I will remove parts of the original questions to make it fair terms of time. On Monday, May 14th, I am going to reserve that day for any make-up exams that need to be completed. 
• On Monday, May 14th, if you have completed all exams, you will be released from class or you can be part of the process of participating in the trial lab for the new AP Chemistry curriculum.  You will receive extra credit for participating in the trial lab event.  You will be required to do the lab and submit a graded lab report to receive the extra credit.  Your lab reports will be sent to the national AP offices to be critiqued for the effectiveness of the lab.  Taking part in a trial like this is special and something that you could include on a resume for college.  I will definitely include it in a letter of recommendation if I write one for you.  
• Remember, I will curve the final and then add the extra credit that you have earned by coming to the early morning sessions and the practice exams. After studying for the real AP Chemistry exam, you should not need to day any more studying for the class final. I will make sure to choose questions that address material that we have covered extensively in class and during the review process.
• For the class final, you will have an equilibrium problem for the first part of the calculator portion of the free response section. I will also guarantee you a reaction rate, thermodynamics (entropy, enthalpy, Gibb's free energy) and electrochemistry question in the either of the two free response sections of the test. I will also guarantee you a question covering chemical reactions like the two given in class in the last week of review.
• Feel free to call or text me on my cell phone if you have any questions as you study. You should all have my number. If not, call someone in class that may have it or email me.  I will check my e-mails frequently over the weekend.
