Majed Al Dhwaihi Chem 151 Lab Prelab Assignment for week 3 Chemical Separation Procedure: Separating the sample: First place a small amount of the spinach provided in the mortar‚ just enough to cover its bottom; combined with the sand provided to break down the call walls. A 1:1 mixture of hexane and acetone was determined to best solvent for this extraction. Knowing this add one mL of the pure hexane and one mL of the pure acetone to the mortar. Grind the contents until the cell walls

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles to separate to the bottom as a particle or pellet‚ and the smaller will remain suspended in the liquid‚ or supernatant. Due to smaller particles separating out first‚ centrifugation is often done in small

First‚ models of the object are generated. Next a viewing specification and lighting conditions are selected. Those surfaces visible to the viewer are then determined and rendered. Thick and thin line It is a popular technique that helps to make the drawing stand out. For this technique‚ thin lines are used in between adjoining surfaces. Thick lines are used when only one side can be seen. It is used to make the drawing stand out. Shading Shading is the process to make a simple line drawing of

Observation Techniques Observation techniques allow a researcher to observe behaviors and reactions in order to obtain information.
