the potential energy is constant along the chain and sharply rises to infinity at the ends. Therefore‚ we can replace the electron system by free electrons moving in a one dimensional box of length . Objective: The purpose of this experiment is to obtain the visible spectra of several cyanine dyes and then interpret them to a simple model of the electronic structure of the π system: the Particle in a Box. Theoretical Model “Particle in a Box” In the Particle in a Box model

Anna Marcon Lab 1 Report June 9‚ 2014 Introductions Background The dominant thumb experiment is used to observe the correlation between handedness and thumb dominance and whether one inherited trait will always influences another correlated trait. Examples of this experiment of this can be traced back as far as 1908. In this experiment 50 people were asked to clasp their hands and the thumb dominance. Once the hands were clasped‚ one thumb would naturally overlap the other and the handedness

THE EFFECT OF CHANGE IN pH ON THE ACTIVITY OF ENZYMES Introduction: Enzymes are catalysts that speed up‚ and control chemical reactions within a cell and break down complex molecules into smaller ones. Some of the chemical reactions that take place in the body produce toxic by-products which need to be converted. The liver produces hydrogen peroxide‚ which is extremely poisonous. When the catalase comes in contact with the hydrogen peroxide‚ it is broken down into water and oxygen. Aim:

Sulfa Drugs: Preparation of Sulfanilamide Introduction The purpose of this experiment is to prepare sulfanilamide from p-Acetamidobenzenesulfonyl chloride. This will be done using reflux‚ vacuum filtration‚ and melting point determination. Experiment Scheme6 Figure 1. Reaction equation.6 A hot water bath was prepared in a fume hood using a 250-mL beaker. 2.5 g of p-acetamidobenzenesulfonyl chloride was placed into a 50 mL Erlenmeyer flask and 11 mL of dilute ammonium hydroxide solution

Rock it out loud: discovering the location of harmonies that make your guitar sing. Purpose: To identify the locations of harmonics on an acoustic guitar and relate them to guitar string lengths. Hypothesis: If I pluck the sixth string of the guitar from frets nine- twelve‚ then those frets will not produce harmonics that are able to be heard clearly. Materials: Acoustic guitar ( adult or child sized) Cloth tape measure‚ metric Lab Notebook Procedures on finding harmonics on your

EXPERIMENT 2: SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement
