INTRODUCTION Shaving gel is a viscous‚ clear gel preparation which is applied before shaving in order to soften the beard‚ lubricate the passage of razor over the face and moisturize the skin. Gels have cross-linked system which exhibits no flow in steady state. Desired characteristics of a Shaving Gel: * It should be clear and transparent. * It should have thick consistency but flowable. * It should lather easily when applied with brush. * It should give clean‚ fresh and moisturized

For instance‚ the reaction between methanoic acid and methanol is shown below COOH+CH_3 OH →CHOOCH_3+H_2 O Purpose The purpose of this investigation is to verify the smell of esters Method Place 250 mL of deionized water in a 500 mL. Heat this water until it boils. Turn off the heat source after boiling Follow the chart below for the following steps Ester # Acid Alcohol 1 Acetic Acid Butanol 2 Acetic Acid Octanol 3 Acetic Acid Methanol 4 Acetic Acid Ethanol 5 Butanoic acid Butanol 6 Butanoic

Physio Cardio Lab Report Answers Activity 1 Questions: 1. Explain how the body establishes a pressure gradient for fluid flow. Pressure gradient is the flow rate of a liquid through a pipe. This is directly proportional to the difference between the pressures at the two ends of the pipe and inversely proportional to the pip’s resistance. The pressure gradient is directly dependent upon blood vessel radius which essentially controls blood flow. The bigger the blood vessel radius‚ the more

perfumes‚ flavorings‚ colorings‚ and medicines. Another type of acyclic acid is methanol‚ and it is also the simplest sort of alcohol. It is a clear liquid that resembles ethanol is odor and properties‚ but it has a slightly lower boiling point of 64.7℃. Methanol is mainly used as a solvent‚ antifreeze‚ raw materials‚ fuel‚ or as a denaturant for ethanol. Unlike ethanol‚ methanol is extremely toxic since one sip of methanol can cause permanent blindness. Two other kinds of acyclic acid are propan-2-ol

still for 15 minutes. we then added the product in a beaker than contain 10 grams of ice. We then vacuum filter the product and wash the crystals with cold water and cold methanol. We then began the recrystallization process. During the recrystallization process‚ the product was a white chucky large crystals‚ when the boiling methanol was added there was a color change from white to yellow. The color change was due to the conversion of aromatic properties. We then place solution in an ice bath to recrystallize

SC/CHEM 3001 3.0 Experimental Chemistry II Experiment A4: Palladium Catalysis: The Suzuki Reaction Abstract In this experiment‚ the Suzuki reaction was performed using phenylboronic acid‚ p-iodophenol and Pd/C catalysis in potassium carbonate aqueous media to synthesize biphenyl-4-ol. The yield of final product was only 11.94% and the measured melting point was 170-175℃. Since the appearance of the product was significantly different from expected light tan color and the measured melting

Pour the reaction mixture immediately after removal from the oil bath‚ into beakers containing 50 mL stirred methanol. A white precipitate should settle out. If the product is difficult to pour‚ add a small amount of toluene (2 mL) to dissolve it and then pour into methanol. 6. Continue to stir in methanol for another 10-20 minutes. 7. Vacuum filter the solid polymer and wash with methanol several times. 8. Air-dry the polymer or dry the polymer in a vacuum oven at room temperature until constant

Lab Day/Time____________ Cardiovascular Dynamics This experiment examines the factors that effect blood flow through a blood vessel. The rate of blood flow is influenced by the pressure gradient in the vessel‚ the radius of the vessel‚ the viscosity of the blood and the length of the vessel. You will be asked to systematically examine each of these factors to determine their effect on blood flow. Getting Started: Login to a CAL lab computer using ZULU Open the PhysioEx program From

Knowing that methanol has a similar backbone structure as nylon‚ carbon-hydrogen bonds and carbon-oxygen bonds are present within the structure. The unknown plastic‚ however‚ does not contain any of the carbon-oxygen bonds‚ carbon-hydrogen bonds‚ or nitrogen-hydrogen bonds.
