You have a mixture of saltwater and  sand. Your task is to get each of the three components pure and separated.  You have learnt the following techniques in the lab. Which one(s) would you use to  effectively  complete this task. Use the letter corresponding to each technique in a sequence separated by ” ;”  to establish your sequence.  a.recrystallisation b. filteration c.drying  in the oven  d. acid-base extraction  e. gas chromatography f. thin layer chromatography g. simple distillation h. fractional distillation

  The given image shows the GC with % area of the first peak at 55% and the second peak at 45% . Based on what you know about GC, you can  say that reaction was  [A] and given that the product mixture  isolated was 3.863 g, you can determine the actual amount of product using the GC to be [B]

Consider the following specifications for a program: A computerized letter is to be sent to high school seniors telling them their graduation status. There are three inputs. The first input is a 10-digit identifying number (ID Number). The second input is the student’s grade point average (GPA) which is a real number. The third input is a real number indicating the balance of the student’s account. For students with 0

You go to the lab to run this experiment. Your lab partner found an old book  which had a procedure (just like Harry Potter found the Half Blood prince’s book in book 6). Some general  ideas are given but some ink on some details had faded out .  The following questions will help you complete the picture.   1. Mix 5 mL 1-phenyl ethanol (molar mass 122 g/mol, density =1.02 g/ml)  with 15 mL of conc. H2SO4 in a ______mL round bottom flask.2. Add a  boiling chip and  gently swirl the contents and heat to boil in a reflux set up for 60 minutes .3.  Cool and collect the organic layer. Add CaCl2 was added. Stopper the flask and allow to  stand for 10 minutes with occasional stirring.4. Decant the product in a pre-weighed product bottle. Weigh the product and calculate the % yield.Analyze the product using GC, IR, NMR and chemical test.   What size RB flask should you pick for your reflux set up ?

Name one chemical test that can distinguish between unknown compounds with following functional groups. Answers are either one or two words only ! a) alkene and alkane [A] b) alkane and 1o alcohol [B]
