Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

cod‚ mackerel‚ shark‚ herring‚ and other species that have been overfished. Naturally harvested fish stocks are now supplemented by aquaculture‚ which supplies about one-third of the fish consumed in the United States. The NOAA Fisheries Service reports that approximately a quarter of all ocean fish species are in danger of extinction. Some scientists believe that most edible saltwater species will near or reach extinction by the middle of the century. The largest fish-including shark‚ Atlantic bluefin

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

250ml of Erlenmeyer flask. 2. 60ml of 10% solution of ethylenediamine is added into the flask. 3. A vigorous stream of air is being drawn through the solution for about 1-2 hours 4. 35ml of concentrated hydrochloric acid is added 5. The solution is then being evaporated on a steam bath until a crust forms over the surface. 6. The solution is cooled and stand overnight before the bright green plates of the hydrochloride‚ trans-[Coen2Cl2]Cl.HCl is filtered 7. During filtered process‚ the product

1. OBJECTIVES (a) To determine the equivalent circuit parameters of a 3-phase squirrel-cage induction motor from laboratory test data. (b) To determine the performance characteristics of an induction motor under load conditions. (c) To control the no-load speed of an induction motor. 2. INTRODUCTION 2.1 Three-phase squirrel-cage induction motors An induction motor is a transformer with a rotating secondary winding. It has two essential components: an outer stationary stator and an

Nervous System lab was designed to measure reaction times by using a variety of tests that affect the heart rate. These tests were the startle‚ stroop‚ Valsalva maneuver‚ diving reflex‚ and a test of our choice. The test our group chose to measure the heart rate in response to doing a trust fall to anticipate the stress right before the fall. To begin this lab we chose a participant‚ and then hooked their finger up to the pulse transducer sensor. Using the chart 5 program on the lab computer the participant’s

is involved with the cannon being fired then the force of gravity would cause the cannon to start to slow down‚ wouldn’t go as far and the direction or trajectory of the cannon ball would be a curved line going down. Purpose: The purpose of this lab is to give the student a better understanding about projectile motion and to understand Newtons theories and laws of motion. We will be firing the plastic ball from the projectile launcher three times from eight different angles from the ground &
