Experimental Measured out 5 mL of 2-methyl-2-butanol and 13 mL of HCl‚ the latter was cooled to approximately 0℃. The HCl was slowly added to the 2-methyl-2-butanol and stirred for 15 minutes. The mixture was then added to the separatory funnel and the aqueous HCl layer removed. The mixture was then washed with 10 mL of H2O‚ 10 mL of sodium bicarbonate‚ and

Rube Goldberg project was to feed the money pig. For our first step a ball rolled down an inclined plane and hit ten dominios. Then the dominios hit a marble for our second step. For our third step the marble rolled off a table and went through a funnel and triggered a mouse trap. In our fourth step the mouse trap went off and a popsicle stick fell off an inclined plane and made a golf ball to roll down it. For our fifth step the golf ball hit another ball on a table. In our sixth step the ball

RUNNING HEAD: Synthesis of Banana Oil Abstract A reflux apparatus was assembled with a water-cooled condenser and a drying tube. Isopentyl alcohol‚ glacial acid sulfuric acid is added to a 25 milliliter round bottom flask and attached to the reflux apparatus. The mixture was boiled‚ the extracted first using water followed by aqueous sodium bicarbonate. The mixture was dried using anhydrous granular sodium sulfate. After dried‚ the sample was placed in a distillation apparatus and heated. This

To achieve it‚ Montresor holds up until jubilee season‚ a period of "preeminent frenzy‚" when Fortunato‚ officially half-smashed and costumed as a fool‚ is especially powerless. Montresor then educates him that he has acquired a funnel of Amontillado wine yet is not certain he has gotten the real thing. Having counseled Fortunato‚ who prides himself on being a specialist on wine‚ including that in light of the fact that Fortunato is locked in‚ he will go rather to Luchesi. Knowing

This case study will be based on analyzing Enterprise Rent-A-Car using the Customer-Value Funnel (CVF). According to McFarlene‚ the Customer Value Funnel (CVF) “serves as both a strategic and diagnostic tool for understanding an organizations current business environment and contexts and the important factors and actors that shape customer value design‚ creation‚ and delivery” (McFarlene‚ 2013). With this funnel‚ the macro environment and microenvironment (Level I & II) will be reviewed‚ and Enterprise

Purpose: In this lab‚ a mixture of naphthalene (C10H8)‚ common table salt (NaCl)‚ and sea sand (SiO2) will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically
