Nucleophilic Substitution Reactions of Alkyl Halides 1. Summary of Experiment In this experiment we will be comparing the both SN1 and SN2 reactions using various compounds and sodium iodide and silver nitrate. We will be comparing the nature of the leaving group (Cl vs Br) in the 1-halobutanes as well as the effect of the structure

influencing the behavior of the participants. Their goal is to be an unobtrusive observer. If the researcher influences the participant while collecting data‚ measurement reactivity occurs. Measurement reactivity is the result of a participant acting differently when they realize that their actions are being observed. Measurement reactivity may require the research to be scrapped and started over as it removes validity from the experiment. Even though observational research takes place in a participants’

Introduction A Voltaic Cell (also known as a Galvanic Cell) is an electrochemical cell that uses spontaneous redox reactions to generate electricity. It consists of two separate half-cells. A half-cell is composed of an electrode (a strip of metal‚ M) within a solution containing Mn+ ions in which M is any arbitrary metal. The two half cells are linked together by a wire running from one electrode to the other. A salt bridge also connects to the half cells. Through electrochemistry‚ these reactions

WEAR___________________________________________________ * Wear is a process of removal of material from one or both of two solid surfaces in solid state contact‚ occurring when two solid surfaces are in sliding or rolling motion. * The rate of removal is generally slow‚ but steady and continuous. Figure 1.4 shows the five main categories of wear. Abrasive Wear: * Abrasive wear occurs when material is removed from one surface by another harder material‚ leaving hard particles

Mindful Meditation and the Brain Some view meditation as new age‚ hippie nonsense because it is not a social norm to sit in silence and dig beneath the surface of the mind. Others liken it to tuning an instrument before playing it. I subscribe to the latter; nonetheless‚ meditation is an ancient practice that can be traced back 2‚500 years. However‚ neuroscientists are just now beginning to measure the effects that it has on the brain. While there are many types of meditation‚ they all have the
