Objective: The purpose of this lab was to use transfer hydrogenation to saturate glycerol trioleate (the main fat in olive oil) to produce glycerol tristearate. Reaction Equations: Theoretical Yield: There was no Theoretical yield in this experiment Procedure: Fill a 50 mL beaker with 30 mL of water and place it on the hot plate. Add 14 drops of olive oil to a 10 mL round bottom flask and then add 1 mL of cyclohexene. Add .05 grams of 10% palladium-on-carbon to the round bottom flask

At the beginning of the lab‚ a micro test tube with and without glass wool was weighed on an analytical balance. A watch glass‚ crucible‚ and lid were also weighed. The masses of all the materials needed for the lab were recorded in the data tables of the laboratory notebook. An unknown vial was obtained from the teacher and set to zero on the balance. About 0.6 grams of the unknown was measured into the micro test tube. The analytical balance was set to zero again and then the test tube with the

Nylon 66 was the brightest blue teal‚ and bleached cotton was blue gray. The name of the azo dye that was synthesized is 2-hydroxy-5-[(4-sulfophenyl)diazenyl]benzoic acid. Worsted wool and silk were the fabrics that were able to absorb the most amount of dye‚ and therefore resulted in the deepest colors for both dyes. Disperse polyester and polyacrylic were the ones that absorbed the least amount of dyes‚ which resulted in the lightest

a word that normally is associated with weather such as frozen‚ snow‚ or temperature references. In the last two lines of the first stanza‚ she cleverly uses the cold‚ white marble like stone alabaster and blanket of wool to represent snow with the words “It fills with Alabaster Wool The Wrinkles of the Road-” (Dickinson lines 3-4). Her puzzling use of punctuation and hyphenated pauses mostly creates metrical rhythm throughout and adds to the lilting qualities‚ although the pause at the end of the

Loft Insulation Research Loft insulation is an effective way to save energy and money in a home. A well insulated house keeps warmth indoors and not letting heat escape. By insulating a loft it will help to heat the home more efficiently. Using less energy reduces carbon dioxide emissions (CO2): which is one of the biggest causes of climate change. Another advantage is that people will also save money on their bills too. [1] Glass fibre or other loft insulation materials are laid across the loft

good thermal insulators. Well-insulated buildings need less energy for heating than buildings that have no insulation. Two building materials that are being used more and more worldwide‚ are mineral wool and polystyrene. Mineral wool is a good insulator because it holds air still in the matrix of the wool so that heat is not lost. Since air is a poor conductor and a good insulator‚ this helps to keep energy within the building. Polystyrene is also a good insulator and is able to keep cool things cool
