INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

On the other hand, if you focus on your best qualities and feel confi- dent that you will attract a mate soon, the creative force will manifest that reality. You have the power to choose your focus. Creation Equation As indicated in Figure 1 on the following page, your core beliefs start the cycle of creation and bring about the experiences you have in life. Your deep beliefs create your thoughts. Your mind is constantly thinking, and you can hear its chatter…

Since acetic acid is considered a weak acid (strong within the scale of weak acids), there is a range at which the acetic acid and acetate will form a stable buffer. Using the Henderson-Hasselbalch equation for buffers, it’s possible to calculate the pH based on the ratio of acid to conjugate base, or calculate the ratio given the pH and pKa value. Finding charge on a protonated amine: The pKa value given for the amino group on any amino acid specifically refers to the equilibrium between the…

function, ("Black–Scholes Model"). Black–Scholes Equation The Black–Scholes equation is a partial differential equation, which describes the price of the option over time. The equation is: The Black-Scholes PDE can be transformed into the heat equation with following change of variables: , , Placing the partial derivatives into the Black-Scholes PDE, we could get: , We can clearly see that the first part of the equation is actually the heat equation. More changes of variables are…

Fresnel Equations The intensity of reflection in between two different medium of propagation can be calculated by using Fresnel’s equation. Light can either be s-polarized, p-polarized or unpolarized. The light radiated by the sun is an unpolarized light. In order to calculate the total reflection of an unpolarized light, we must first solve the reflected light using the Fresnel equation for s and p polarized reflection. For simplification purpose, the derivation of Fresnel’s equation will be…

Differential Equations was the course that made me question my decision in taking up Chemical Engineering. I actually had no idea it was this challenging. All I had in mind was that it’s just Calculus 1 and 2 combined. Before we officially started the class, Engr. Cabatingan introduced us the syllabus and made us study it. The topics were “bearable”. However, I really had no idea what was Modeling all about. We even joked about it, more so when we knew that there’s going to be a gallery walk. In…

amount of force placed on an artery at any given point in time. R= resistance Is the force that must be overcome for flow to occur. Describe the basic flow equation and resistance equation as they relate to vascular flow. b. Define Poiseuille’s Equation, and describe the effect on blood flow of a change in each variable. Poiseuille's equation states that the velocity of the steady flow of a fluid through a narrow tube varies directly as the pressure and the fourth power of the radius of the…

Unfortunately, there are many obstacles in society that will occur and effect plans that are currently in place contract wise. Those obstacles can generally be resolved with little to no hesitation, but some can become a bit more challenging. For those that become more challenging, they quickly move from the area of being identified as obstacles to being considered damages. With that being said, punitive damages are “generally not awarded in an action for breach of contract,” according to…

with fear once again. These ideas are expressed in the two short stories “The Cold Equations” and “Hinterlands” which establish the basis for what it means to be sacrificed. William Gibson and Tom Godwin, in their respective short stories, explore the ideas of whether or not a person's life is truly significant or valuable in the eyes of others by critiquing the mentality that inhabits it. In the story “The Cold Equations” by Tom Godwin, we hear the story of an EDS pilot delivering…

WT, PV, SB, GT, and utility grid. The main objective functions of this system are the total annual cost (TAC) and the system pollution (SP). Equation 3 shows the multi-objective function should be minimized. f=min⁡(TAC,SP) (3) Equation 4 shows the first objective function, which it represents the TAC; 2.1 TAC Calculations TAC=(∑_i▒(I_i+〖OM〗_(P_i )-S_(P_i ) ) )/N_P…
