Experiment #7 Fall 2014 Dehydration of an alcohol NAME Nick Weinberger POSTLAB 1. Show the mechanism for the dehydration of -tetralol under conditions employed in the lab. Show all intermediates‚ and show electron flow with arrows. 2. What general mechanism most likely applies to this reaction (SN2‚ E2 etc)? E1 3. Why was acid employed in this reaction? The acid was used to protonate the leaving group (OH) to form water which is a much better leaving

1061: Principles of Chemistry I Gas Laws Gas Laws: Pressure‚ Volume‚ and Temperature Introduction Pressure‚ volume‚ and temperature are properties of gases that reveal their relationships when any one of them is varied. Changing the temperature of a gas may change its volume or pressure‚ but how? What are the mathematical relationships between these properties? Are there limits to them? Scientists have discovered through the study of properties of gases that there is indeed a theoretical limit to

Experiment 1: Calorimetry Nadya Patrica E. Sauza‚ Jelica D. Estacio Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (∆T) was calculated by subtracting the initial temperature

damage to 14 % of its forest trees. In this experiment‚ I will find out what consequences acid rain has on the germination and subsequent growth of cress seedlings. I will use cress seedlings‚ which germinate quickly and can grow a few centimetres in a matter of days and sodium metabisulphite‚ which reacts slowly with water to produce sulphur dioxide gas. The seedlings will have to be in an enclosed system so the sulphur dioxide does not escape. The experiment is a simulation trying to model a powerstation

Gimme Experimental is a short experiment but tests a very interesting psychology concept: the endowment effect. The endowment effect simply is the expectation that if a person owns something they place a higher value to it. Conversely‚ there is another psychology term called the reverse endowment effect. This is the complete opposite of the endowment effect‚ which means a person would place a higher value for someone else’s possession. Interestingly‚ this experiment does not take long at all. Kids

William Edwards Deming was a master of quality improvement. His demonstration called the “Red Bead Experiment” was an amazingly simple‚ but effective way to highlight some problems in quality management. The example‚ which he used in many of his seminars‚ involved a batch consisting of approximately 80% white beads and 20% red beads. A group of willing workers were trained to use paddles that collected samples of beads for quality testing. The workers showed their paddles to managers who would then

MATERIALS AND METHODS This experiment contained two parts‚ a “PART A” consisting of blood pressure measurements‚ and a “PART B” consisting of linear displacement measurements. The equipment used in “PART A” consisted of an OMRON manual sphygmomanometer with a stethoscope attachment as the manual blood pressure meter‚ and a ReliOn Manual Inflation Blood Pressure Monitor model HEM-412CREL as the automated blood pressure meter. The pressure accuracy of the automatic meter was 3 mmHg and held a displayed

research experiment to study how people conformed to the roles they are given. The experiment was set up in the basement of Stanford Psychology building. Zimbardo’s goal was‚ “... to understand more about the process by which people called “prisoners” lose their liberty‚ civil rights‚ independence‚ and privacy‚ while those called “guards” gain social power by accepting the responsibility for controlling and managing the lives of their dependent charges” (Zimbardo par. 11). Although the experiment was

Lab Report Experiment Aim: To determine the acceleration of an object down an incline plane using various methods. Research Question: Is there a relationship between the angle θ of the incline and the acceleration down the plane? Equipment: * Ticker Timer (AC 50Hz ) * Incline (wood) * Meter ruler * Dynamic Trolley ( Mass: 380.55 ± 0.01g ) * Carbonated paper * Power Source (2W) * Data Logger * Motion Sensor * Tennis Ball Method

in the Mentos and Diet Coke. The structure of the Mentos allow carbon dioxide bubbles to form extremely rapidly. When this happens‚ you get the physical reaction of the coke exploding out of the bottle. Other carbonated drinks also work with this experiment. (Hiskey) One thing that contribute to this explosion is the structure of the Mentos. Mentos are fairly dense and sink rapidly‚ quickly creating bubbles that seed further
