Molecule Polarity PhET Lab A study of electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place

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

Introduction: The purpose for this experiment is to get familiar with basic properties and applications of the integrated-circuit operational amplifier‚ the op amp‚ one of the most versatile building blocks currently available to electronic-circuit designers. The emphasis will be primarily on the nearly ideal‚ on what is easily and conveniently done. Exploration of what is less-than-ideal about commercial operational amplifiers will be deferred to later experiments. For the procedure
