Constant

In this project the aim is to determine the equilibrium constant (Kc) of a weak base when it reacts with a weak acid. The chemicals I wish to determine the equilibrium constant for are, Ethanoic acid (CH3COOH) and Propanol (C3H7OH). To accomplish this, the first question we must ask is, “what is an equilibrium constant and how is it determined”? There are 2 different types of equilibrium. The first, and the type we shall be using is known as homogeneous equilibrium which has everything present in the same phase. The usual examples include reactions where everything is a gas, or everything is present in the same solution. K is the universal equilibrium constant for reactions. There is also Kc and Kp, however Kp applies to reactions of gases,…

Introduction The human world is in a constant state of flux. In fact it might be safe to say that change is the only constant that we humans can expect. No matter where you look something is shifting, whether that be our physical environment or the technological world of which we are part. Technological developments happen so rapidly that at times they can make more familiar components of our lives, such as libraries, seem outdated and antiquated. However it is the pairing of the two,…

title>INTRODUCTION Optical constants (complex refractive index n, complex dielectric function ϵ, and reflection and absorption coefficients R and α) of materials are of great importance for optical metrology in the semiconductor industry.1,2 A high-performance complementary-metal-oxide-semiconductor process flow with 11 layers of metal requires about 75 photolayers and may contain up to 100 thickness measurements, most of them performed using spectroscopic ellipsometry.3 This technique has…

According to the PBS Frontline interview, “Digital Demands: The Challenges of Constant Connectivity,” we are witnessing a generation of adolescents who would rather experience human interaction through texting in place of calls or “face to face” correspondence, sighting the efficiency of technology and the safety of distant intercommunication. Consequently, the interview indicates that adolescents are being stripped of the opportunity to build interpersonal skills due to their overuse of…

The Constant Gardener and the art of planting ideas. When you hear the words “political thriller” you may imagine some national treasure type shenanigans, brash loud action heroes and more explosions than perceptive dialogue. The Constant Gardener however has an altogether softer approach exploring themes of morality which are subsequently much more empowering and the journey of a grief stricken man. “If I tell you that girl over there is being murdered, will you believe me?”. The Constant…

To begin the Constant Stimuli experiment, the lab recruited three subjects including two undergraduate students from the UCI Psychology department subject pool and the author, to finish the tests. All subjects were randomly distributed for gender but most of them were aged from 19 to 21. The subjects, included the author, can be considered naïve because none of them had done similar experiments before. All subjects were informed by the researcher about the purpose of the experiment and they held…

Constant change is a business reality, and organizations must continually change to their situations to stay competitive or risk becoming outdated. That is why the ability to adapt successfully is critical in a prosperous business. In this essay we are going to discuss the main key elements of change, reasons for change, how to deal with change, and the results of change. A business development plan is not something that forever controls how your business must function. It 's a starting point,…

have been washed away, Jesus had died and resurrected for him or her, he or she has been born new, one is a Christian, and especially has a new Christian name, there is a new concept involved of having died and resurrected in Christ. On another note, if there is a contrary circumstance related to one’s living out the baptism, one is tempted to ask what happens if one think he or she is not a believer of Christ. Of the claim that since God has given us free-will, one has the choice of making…

plot should look when reaction goes to completion. Did [Pb] approach a constant value? Behaviour of [Pb]-time plot indicates which samples to omit. Which α function best fit results? The origin of our two alpha functions has been derived and explained in the MTRL 359 Lab Manual, the mathematical significance of each function are as follows: The above equations are [15] and [21] respectively, where equation [15] is a description of the Diffusion Limited Rate Model and equation [21] is a…

The purpose of this lab is to solve for the equilibrium constant of a reaction between iron (iii) ions and thiocyanate ions. The lab is divided into two parts: one section recording absorbance of reference solutions and the other part for the absorbance of test solutions. The reference solutions were created through the mixing of excess iron (iii) nitrate (Fe(NO3)3) with a known concentration of potassium thiocyanate (KSCN) in order to push the reaction to completion; the initial concentration…
