Molecular Modeling Exercise The purpose of the is lab was to practice modeling molecules and exploring the capabilities of the ChemOffice programs. The minimum energy was found for each of the three molecules tested and the strain energy at different dihedral angles was plotted. The first molecule‚ butane‚ was easily completed but amphetamine and U4EA caused some difficulty. The results of the last two were not very conclusive. INTRODUCTION The purpose of this lab was to explore the capabilities

ABSTRACT A molecular diffusion experiment was conducted with the goal of determining the diffusion coefficient of acetone into air. For this experiment‚ acetone was placed in a capillary tube and was allowed to diffuse into non-diffusing air that was passed over the test tube at the temperature of 50oC.Thetemperature is kept constant and air stream is passed over the top of the tube to ensure that the partial pressure of the vapor is transferred from the surface of the liquid to be air stream bymolecular

Diversity In America By: Jason Lundy Webster’s dictionary defines diversity as‚ “the condition of being different: variety.” The United States of America is very diverse. We have had some influential people that have helped steer us in the ways that we know diversity today. Dr. Martin Luther King Jr. was very influential in changing the way many white Americans looked at African- Americans during the 1960’s. Long before Dr. King marched on Selma‚ Alabama and gave his “I Have a Dream” speech in

neurotoxin that can be deadly (Geiling). What give the phytoplankton the conditions to grow are the increasing temperatures of the oceans. Emissions are coming from places like cement production (which is a leading cause) deforestation‚ and fossil fuels like coal‚ natural gas and oil‚ which increase carbon emissions‚ which in turn‚ increase ocean temperatures. Without a human element on earth‚ the normal rate of carbon emissions would be drastically lower than what is it today and ocean temperatures

Carbon nanotubes describes a specific topic within solid state physics‚ but is also of interest in other sciences like chemistry or biology‚ actually the topic has coating boundaries‚ because we are on the molecule level. The carbon nanotubes have in the recent years become more and more popular to the scientists. Initially‚ it was the spectacularly

For every role that is "performed" in one’s life‚ the antithesis of that role also is performed. As I examine my many roles that I play in life‚ I realize that the majority of my time spent on this planet has been filled with learning. We all are eternal students‚ I guess you could say; this would at least be true in an ideal world. And for every individual whom consumes his or herself with being a student‚ that person also is a teacher. Too often the definition of teaching gets associated with

The Roles in Young Man’s Life During the course of our lives‚ we must take part in some roles. Some of these roles‚ are important‚ others are not. Being young is a great opportunity to experience some of the important roles that will benefit us for the rest of our life. Taking appropriate interest in our actions is what makes us improve our roles. No matter what we do‚ there will always be responsibilities that we must learn to face in order to succeed in life. Young men have three important
