the Equilibrium Constant for Ferric Thiocyanate In this laboratory exercise‚ the equilibrium constant(Kc) for the reaction between the Ferric Ion (Fe3+) and the Thiocyanate Ion (SCN-) was determined. After measuring the absorbance of the Ferric Thiocyanate‚ and carrying out some calculations; it was determined that Kc=130.81M Introduction: Chemical equilibrium is established when a reaction exists in a state where the forward reaction rate is equal to its reverse reaction rate. The overall reaction

CHAPTER 4 (MANKIW) INFLATION RATES AND INTEREST RATES: THE FISHER EQUATION NOTES by: Chadia Mathurin Economists differentiate between real and nominal interest rates where: real interest: is defined as the increase or decrease in a consumer’s purchasing power experienced as a result of changes in the interest rate. nominal interest: is defined as the interest payed by the bank. Let: i denote the nominal interest rate r the real interest rate pi ‚ the inflation rate The equation for the

Communist Party of the Philippines (CPP)‚ and the Muslim separatist movement of the Moro National Liberation Front (MNLF). One of his first actions was to arrest opposition politicians in Congress and the Constitutional Convention. Initial public reaction to martial law was mostly favourable except in Muslim areas of the south‚ where a separatist rebellion‚ led by the MNLF‚ broke out in 1973. Despite half-hearted attempts to negotiate a cease-fire‚ the rebellion continued to claim thousands of military

Effect of different temperatures on the rate of an enzyme controlled reaction I will place starch and amylase into five water baths which are at different temperatures‚ and record the time it takes to break down the starch in the solution. Independent variables The independent variable is what I am going to change in my experiment. In this case it is the temperature of the water in the five water baths- 10‚ 25‚ 40‚ 55‚ 70 degrees Celsius Dependant variable This is what will stay the

All children are unique and develop at their own rate but they tend to follow a similar pattern. There are a number of areas of development like‚ Physical‚ communication‚ Social‚ emotional‚ behavioural‚ Intellectual and moral development. Development is very rapid in the early years of a child’s life and tends to slow down the older they get. Moral development is usually adapted from the setting a child lives and would usually deem something wrong and right‚ based on what their parents believe is

My Reaction Paper This is my reaction paper on a movie that I watched entitled “The Wizards Of Waverly Place: The Movie”. Wizards of Waverly Place: The Movie follows the Russo family as they embark on a vacation to the Caribbean resort where Jerry and Theresa first met. Alex‚ upset that she was forced to accompany her family on the trip‚ conjures a spell that erases her parents’ fateful first meeting and puts the Russo family’s very existence in peril. In order to reverse the spell‚ Alex

1. Determine the spring constant‚ k‚ of Spring 1‚ by using Hooke’s Law. Take three different measurements (since 3 masses) and do three calculations and average your k’s to get a more accurate answer. By applying lots of friction‚ you will be able to get your mass to hang still. Show a table of your data and your calculations of k. Spring 1 with three different masses: 50 grams: Spring stretched: 5m F = 50gm * 9.8 m/s2 = 490.00 N K= 490/5m = 98 100 grams: Spring stretched: 10m F = 100gm * 9

To begin the experiment‚ the reaction apparatus was assembled (as shown in Figure 1 below from the lab manual) consisting of a 3.0 mL conical vial charged with p-cresol (80uL from Eppendorf pipette)‚ 25% aqueous NaOH (130uL)‚ and a spin vane. The solution was mixed thoroughly and tetrabutylammonium bromide (9mg) was added along with n-propyl iodide (75uL) and it was equipped with a flask with a water reflux condenser. The solution was heated (95-100°C) while vigorously stirring it. After 60 minutes

31) QUALITY OF DRIED FOODS AND DETERIORATIVE REACTIONS DURING DRYING Consumer demand has increased for processed products that keep more of their original characteristics. In industrial terms‚ this requires the development of operations that minimize the adverse effects of processing. The effect of food processing on finished product quality ultimately determines the usefulness and commercial viability of that unit process operation. In the particular case of food drying this indicates that loss
