Nernst equation

the example equation below: Atomic Absorption Calibration Data We were asked to prepare a 10 g/L HCl solution from a 200 g/L standard solution, and found the volume by: Thus, we add 5 mL of 200 g/L HCl to get 100 mL of our 10 g/L HCl solution.…

CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…

investors will not pay for risk premiums, and defined by following stochastic differential equations: (1) (2) Where: S(t) represents the price process of an underlying assets. V(t) is the variance of the corresponding instantaneous returns. And the initial condition S(0), V(0) should be strictly positive. r is the risk-free return rate (non-negative…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

Influenced through encounters with China and the West, the Japanese explored mathematical topics that were relevant to their time, which led to Japan’s shift from wasan (和算, Japanese Mathematics) to yôsan (洋算, Western Mathematics) in the Meiji era, and ultimately various technological advancements. As seen in Japan’s first encounters with the west, Sakoku (鎖国, the national seclusion policy) was the direct result of distrust of the Christian missionaries, which led to limited trade of ideas. In…

diluted with DI water and reacted to produce an unknown amount of FeSCN2+ ions in an equilibrium reaction. The absorbance of each solution was found using a spectrophotometer, the first five of which was used to create a calibration curve, whose equation relates the concentration and absorbance of FeSCN2+ ions. Theories…

Genealogists photograph tombstones to document the birth, death and burial information of their ancestors. This post will give you some tips on how to get the best possible results when taking those important pictures. Locating Cemeteries Your first challenge might well be just getting to the cemetery. Hopefully you have an obituary or burial record for your ancestor that gives the name of the cemetery. Depending on how old the record is, finding the cemetery can be very easy or impossible.…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…

a quartic function can only have 4 rational/irrational zeros, 2 rational/irrational zeros and 2 complex zeros, or 4 complex zeros. I was able to find how many positive and negative zeros I had using the Descartes Rule of Signs. Using the original equation, I counted from left to right, the amount of sign changes, and that gave me number of positive real zeros. I discovered 2 positive and 2 negative real zeros using this method. Now to find the negative number, the exact same process is repeated,…

INTRODUCTION The trends in physical properties of organic compounds such as boiling points and melting points can be deducted from their structures, including size (molecular weight, surface area), shape and functional groups. These factors significantly influence the strength of the intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at…
