6.1 ABSTRACT The densities (ρ) and viscosity (η) were reported for binary mixtures of N-methylformamide with O-substituted aniline (2-chloroaniline‚ 2-methylaniline and 2-methoxyaniline) over the entire composition range from 303.15 K to 318.15 K and at atmospheric pressure 0.1 MPa. These experimental data have been used to calculate excess volume (VE)‚ deviation in viscosity (∆η) and excess Gibbs energy of activation of viscous flow (G*E). The variations in these properties with composition for

1) First‚ all the materials were gathered and the Boiling point apparatus was assembled. 2) Two mL of methanol were poured into a dry test tube‚ and two small boiling stones were added. The tube was secured to a ring stand so that the surface of the methanol was slightly below the oil level in the beaker and the tip of the thermometer was about 1 cm above the surface of the methanol. 3) The mineral oil was heated. The temperature of the oil bath was checked with a different thermometer

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

Purpose: I will identify an unknown liquid by obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric

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

amount of blood flowing through a vessel‚ tissue‚ or organ during a given period of time and Blood pressure is the force exerted on a vessel wall by the blood traveling through it. 2. Describe the relationship between blood viscosity and blood flow. As blood viscosity increases‚ blood flow decreases. 3. Describe the relationship between vessel radius and blood flow. Vessel radius has a direct relationship with blood flow. As blood vessels constrict (vasoconstriction)‚ blood flow is decreased
