Question
9. A student recovered 1.375 grams of acetarilide and i 067 grams of benzoic a composition of the original mixture? (The % BA and the % AC) What is the percent 10. How does the melting point of an impure sample compare to that of a pure sample? Is it higher lower or the same? 11. When using a separatory funnel with water and dichloromethane which layer is on top and which is on the bottom? How about with ethyl acetate and water? 12. Draw a balanced chemical equation for the reaction of hexanol and acetic acid and a catalytic amount of sulfuric acid to get hexyl acetate 13. A student starts with 2.50 mL of hexanol and reacts it with an excess of acetic acid. The student recovers 2.13 mL of hexyl acetate. What is the student's percent yield for the reaction? Hexanol-molecular weight 102 g/mol density 0.814 g/mL Hexyl acetate -m.w. 144 g/mol density 0.867 g/mL 14. Draw a simple distillation set-up include water hoses, which is water in and which is water out, in addition to clamps and thermometer placement.Explanation / Answer
Q10
melting point typically decreases as there are impurities, they will lower the melting point due to colligative properties of the metal.
it will be LOWER
Q11
Density of Dichloromethane = 1.33 g/mL
density of water = 1.0 g /mL
by density differences, the heaviest (Dichloromethane) must go on top layer and water (H2O) must go on the top layer
