Task 6. An unknown hydrocarbon fuel combusts with air; the resulting products have the following dry volumetric analysis: 12% CO₂, 1.5% CO, 3% O₂, and 83.5% N₂. Calculate the percent excess air. C13.5 H25.8 Percent of theoretical air = 111.3%
with a theoretical yield of 80% compute for the percent error of the following data Vial weight= 18.3501 vial + fluorescein weight=18.442 resorcinol = 0.1502g Phthalic anhydride= 0.1022g
1.Each of the student statements below is wrong. You will need to explain why they are not correct. (a) All my compound dissolved right away in the small amount of solvent I added at room temperature, and I didn’t need to heat it at all. This means I’m going to get lots of pure compound out. (b) I did a recrystallization of naphthalene and my percent recovery was very high (99%), so I must have pure product. (c) When you’ve dissolved all your compound in hot solvent, and you’re in a hurry, it’s ok to just place it straight into the ice bath.
Solve: a. Calculate the percent yield of X when solvent D is used. Answer in 4 significant figures with proper unit. b. Calculate the percent yield of X when solvent E is used. c. Calculate the percent purity of compound X using D and E as recrystallization solvent. %purity = [mass of pure sample/(mass of pure sample + mass of impurity) x100
Show the theoretical and % yield calculations for your synthesis. Please be sure to use appropriate identifiers and conversion factors. 5.0mL acetic acid (5.3g) 3.0mL 1-octanol (0.829 g/mL) 25 drops of concentrated sulfuric acid (1.5mL total). If necessary, assume 1 drop to be 0.05mL.
1-A bottle of Na2EDTA.2H2O is labeled with an assay of 100.5%, what is this implied?What is the result of heating to 100 ºC?
Andrea and Yvette are going to cook the most delicious food that ever going to exist for their tired classmates that conducted the experiment in an organic chemistry laboratory. However, the stores are closed and they don’t have a table salt for the seasoning of their special dish so they need to use the laboratory grade sodium chloride as alternative. There are two unlabelled reagent bottle in the laboratory containing either sugar or sodium chloride. Devise a systematic flow chart to identify the sodium chloride between the two reagent bottles.
Please, I need help to do question 2 for the post-Lab questions These is my values obtained in the laboratory : volume of cyclohexanol = 7.39mL ; mass of cyclohexanol = 7.112 g mass of cyclohexanone obtained = 1.535 g Thymol blue = 3 drops volume of Sodium Bisulfite = 1mL volume NaOH used = 20mL Continuation of the procedure 2- Place 0.0700 mol (How many mL would this be?) of cyclohexanol into the RB flask. To it add 6.00 mL of glacial acetic acid. 3- Turn on the stirrer slowly (not the heater!). Make sure the stir bar will not hit the tip of the thermometer. Add 82 mL of a 8.25 % w/w bleach solution (NaOCl (aq)) into the separatory funnel and slowly drip the bleach into the solution at such a rate that the temperature stays between 40-50 °C. The reaction is exothermic and you do not need to heat this reaction with the hot plate. However, do not allow the temperature to go below 40°C as the oxidation would be incomplete.…
A student rushed through this experiment. Describe the effect that the following procedural changes would have on the percent recovery of acetanilide. Briefly explain the basis of each answer.(a) Rather than adding 0.5-mL portions of boiling solvent to the acetanilide, the student added 5-mL portions of boiling solvent.(b) The student did not pre-heat the gravity filtration apparatus.(c) The student forgot to cool 5 mL of solvent in Part 5 and washed the crystals with room-temperature solvent.
Please, I need help to do question 3 for the post-Lab questions. The question is, Which was the limiting reactant in your oxidation of cyclohexanol? Explain clearly, showing any calculations necessary to lead you to our conclusion. These is my values obtained in the laboratory : volume of cyclohexanol = 7.39mL ; mass of cyclohexanol = 7.112 g mass of cyclohexanone obtained = 1.535 g Continuation of the procedure 2- Place 0.0700 mol (How many mL would this be?) of cyclohexanol into the RB flask.

Write TRUE if the underlined word/phrase makes the statement correct. Otherwise, write the correct WORD/PHRASE that will make the statement true. If there are two bold words/phrases in a number, write your answer for EACH of the bold words/phrases 1. 6-hydroxy-1-naphthoic acid is soluble in 5% NaOH and soluble in 5% NaHCO3. 2. The addition of excess charcoal would decrease the % recovery in the purification by recrystallization. 3. If the target compound is contaminated with impurity, the melting point will be higher than the theoretical value and the melting range is large.
Please give an explanation and show work step by step: Write a balanced equation for the combustion of benzoic acid, C6H5COOH, to give CO2 and H2 How many milligrams of CO2 and of H2O will be produced by the combustion of 4.635 mg of benzoic acid? Combustion of 732 mg of an unknown organic compound gave 16.432 mg of CO2and 2.840 mg of H2O. (a) Find the wt% of C and H in the substance. (b) Find the smallest integer mole ratio of C:H in the compound.
