The Resultant of Multiple Forces

By: Diane Krehbiel Goal: The goal of this experiment is to use a force table to see the effects of adding vectors. Multiple forces will be attached to a center point. Force components will be added and subtracted both graphically and trigonometrically.   Introduction: Vectors are quantities measured in both magnitude and direction. They are usually represented by an arrow. Two vectors are considered equal despite of the initial points as long as the vectors have the same magnitude and direction […]

Oxidation of 2-Ethyl-1,3-Hexanediol with Calcium Hypochlorite

By: Nathan Gaffney Introduction/Purpose The purpose of this lab was to learn about the oxidation of alcohols. The starting compound was 2-Ethyl-1,3-Hexanediol, one of the hydroxyl groups was first degree while the other was second degree. The reagent used was calcium hypochlorite. Since the starting material was a diol the product outcome could have been a variety of products. That is why the results of the lab were investigated via IR to determine if the reagent calcium hypochlorite was a strong […]

Kinetic and Thermodynamic Control of a Reaction

By: Ashley Martin Introduction This experiment explored the concepts of thermodynamic and kinetic products and controlling the formation of each product of the reaction of semicarbazide hydrochloride and cyclohexanone as well as semicarbazide hydrochloride and 2-furaldehyde.  The kinetic product is formed under conditions where reactions that require a lot of energy are irreversible or in which there is no equilibrium achieved. The amount of product is determined by their rates of formation, which correlates to the height of the transition […]

Nuclear Power – The Future of Energy

The Future of Energy   A famous physicist once said, “A man should look for what is, and not for what he thinks should be.” This physicist was Albert Einstein, the father of nuclear fission. Though it may have been contextually related to physics, this virtue can be applied towards our current energy crisis, and the means in which we contest it. That is, rather then looking for an energy source that appeals to what we want, we should use […]

Coal – Implications and Consumption

Coal With temperatures rising and ice melting, the issue of energy consumption and production has gained more and more attention. In the United States we have focused our attention to the most prevalent forms of our energy consumption, fossil fuels. In this assignment I was assigned a specific fossil: coal.  With over fifty percent of the nations electricity coming from coal fire power plants, it is important to realize the implication behind the coal consumption process. In today’s modern coal […]

Distillation – Lab Report

By: Victoria Anatsui Introduction: The purpose of this lab is to learn the important separation methods of distillation/fractional distillation. These methods separate miscible liquids by utilizing their differences in boiling point. Simple distillation is great for separating liquids with very large differences in boiling points while fractional distillation is better at separating liquids with closer boiling points. Procedure: We set up both a simple and fractional distillation apparatus with 60ml of a methanol/water mixture (Unknown Bottle C) in a 100ml […]
