Pg. 2 due 11/20 25-30 Multiple Choice Questions 3 FRQ AP Questions AP Test Curved 75% M.C. & 60% F.R.Q. 5 100% Note: on the AP test, you will not know everything, get used to seeing questions you may not know, so there may be 2 or 3 multiple choice questions that you have not seen, do your best! Note #2: On the M.C. of the real AP test, you will not be able to use a calculator, but on the FR you will. There may be some empirical formula questions! Bonus Question Working with your lab group, solve the set of questions given to you 2) After each section, get it checked by the teacher and signed off! 3) Move onto the next section! 1) 4) Last question, assume at STP! -Once finished, do the Study Guide Activity; first you figure out how to make the solution, then you will need: aluminum foil, a beaker, graduated cylinder, balance and copper (II) sulfate 1) Solve how you would make the solution indicated in the first part. 2) Have it checked by your teacher 3) Once you are ready to make the solution, Have your safety glasses on! Use lab equipment to carry out your procedure Answer the questions at the end Talk to your teacher at the end about what you think was happening For clean up, put the “gunk” into the LARGE beaker, and then rinse out your beaker. Make sure your area is clean! -Once finished, finish the Limiting Reactants Activity from last week, check your answers on the cabinet. And show your instructor! -If you still have time before Exit Ticket, go over any HW problems/work on Study Guide Questions! 1 N2 (g) + 3 H2 (g) 2 NH3 (g) If 20.5 grams of nitrogen reacts with 5.0 grams of hydrogen, how many liters of ammonia at STP can you produce? What is the limiting reactant? -After you finish put your pen/pencil away, and get a highlighter, different color or a marker OUT!! -If you do not have a highlighter, wait until I say to go grab one! Hint: see how many liters of ammonia you can produce from 20.5 g of Nitrogen and see how many liters of ammonia you can produce from 5 grams of hydrogren (set up two equations!) *Turn in Exit Ticket Put a Put a for a correct answer for an incorrect answer, but attempted (work is there) Put a for a blank answer (no attempt) *This should be done in a different color!
