MOLECULAR MODELING 1. Objectives ● Predictthe shape of identified compounds; ● Construct molecular models of identified compounds; and ●Determine the molecular structure of identified compounds. 2. Theory Building models of molecules are useful for visualizing how atoms are connected in three-dimensional space called molecular geometry‚ which is best predicted by Valence-Shell Electron-Pair Repulsion (VSPER) theory. The following are the sets of rules summarizing thsi theory: ●

Molecular modelling is the general term used to describe the use of computers to construct molecules and perform a variety of calculations on these molecules in order to predict their chemical characteristics and behaviour. The term molecular modelling is often used synonymously with the term computational chemistry. Computational chemistry is a broader term‚ referring to any use of computers to study chemical systems. Some chemists use the term computational quantum chemistry to refer to the use

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

ARTICLE REVIEW Separated Twins and the Genetics of Personality Differences: A Critique Author(s): Jay Joseph EDP 1002 : THEORIES OF PERSONALITIES Introduction Throughout history‚ across all cultures‚ people have been fascinated with twins. In addition to interest in the close emotional ties and biological similarities that twins may share‚ reports of special twin languages and twin extrasensory perception (ESP) help people to explore ideas of what it means to be human.

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

Speech I. The history of molecular gastronomy Molecular gastronomy is a new discipline about food science. This science investigates‚ explains and makes practical use of the physical and chemical transformations of ingredients that take place while cooking. But the truth is‚ using this science in cooking is not new. Pioneer Professors Evelyn G. Halliday and Isabel T. Noble: they said in their book “The main purpose of this book is to give an understanding of the chemical principles upon

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

MOLECULAR FARMING INTRODUCTION Biotechnology in agriculture has two categories: 1. “Improvements” to existing livestock and crops‚ and 2. Development of entirely new uses for both animals and plants (biopharming). “Improvements"‚ include ‘input traits’ such as crops with extra resistance to insect attack‚ improved weed control‚ increase the plants tolerance to cold‚ drought and other environmental factor. Ex "Roundup ready" soya‚ "Starlite" corn‚ or "Frost-tolerant" tomatoes. WHY PLANTS

factor in a person’s personality or if it really is the nurturing environment. They wanted to see if twins who were separated at birth and raised in different environments would still have similar personalities‚ which support the theory that a person’s genes has more impact on a person’s character than the environment. In order to study their hypothesis‚ Bouchard and Lykken located identical twins that were separated by birth due to adoption and spent a week conducting various tests; four personality
