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

Apportionment Using the Hamilton Method Dawn Ambrose Argosy University- On-line MAT109 A01 Instructor: Marcus Vandiver Apportionment Using the Hamilton Method Using the Hamilton method of apportionment‚ determine the number of seats each state should receive. Using the numbers you just calculated from applying the Hamilton method‚ determine the average constituency for each state. Explain your decision making process for allocating the remaining seats. As can be seen in the chart above

4 Pages Write a paper answering the questions below using examples from the Dumas book and the course (but you MUST use the Dumas book as a resource). What does Dumas’ decision to take an American name suggest about her feelings toward her adopted country? How does her dual identity enable her to see how Americans "really" feel about Iran? Dumas’ husband‚ François‚ experiences life as an American immigrant much differently than does Dumas. What do you think accounts for Americans’ biases in

in water using the method of solvent extraction‚ also known as liquid-liquid extraction‚ a method of separating two materials with different physical and/or chemical properties. Two methods of evaporation will be used to finally determine the concentration of impurity- one using an explosion-proof hot-plate‚ and one using a rotovap. III. Theory Fig. 1a+1b. Figure 1a shows how water and oil separate in the separatory funnel‚ while figure 1b shows the actual apparatus. Liquid-Liquid extraction

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

an area of low concentration. How quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances. The methylene blue and potassium permanganate (KMnO4) was used and placed in the plate. Because the two substances have distinct colors‚ the measurement

MOLECULAR ELECTRONICS INTRODUCTION Molecular electronics (sometimes called moletronics) is a branch of applied physics which aims at using molecules as passive (e.g. resistive wires) or active (e.g. transistors) electronic components. The concept of molecular electronics has aroused much excitement both in science fiction and among scientists due to the prospect of size reduction in electronics offered by such minute components. It is an enticing alternative to extend Moore’s Law beyond the

Alexandre Dumas‚ père‚ born Dumas Davy de la Pailleterie (24 July 1802 – 5 December 1870)[1] was a French writer‚ best known for his historical novels of high adventure which have made him one of the most widely read French authors in the world. Many of his novels‚ including The Count of Monte Cristo‚ The Three Musketeers‚ Twenty Years After‚ and The Vicomte de Bragelonne were originally serialized. Life [edit] Early life Alexandre Dumas was born in Villers-Cotterêts in the department of

The History of the Dumas from 1906 to 1914 was a History of lost opportunities by the Tsar and his Ministers’. Assess the validity of this statement. In the setting up of the first duma the tsar and his ministers had the opportunity to meet the demands of the people without having to lose any authority or change the system that was already in place too drastically‚ he also could have given the people representation that they so desperately wanted. The events of Bloody Sunday made the Tsar
