Spectrophotometric Determination of an Equilibrium Constant Introduction: In this experiment‚ you will study the reaction between aqueous iron (III) nitrate‚ Fe(NO3)3‚ and potassium thiocyanate‚ KSCN. They react to produce the blood-red complex [Fe(SCN)]2+. Fe3+ + SCN- ( [Fe(SCN)]2+ The equilibrium constant expression may be expressed as: K = [pic] You will prepare a series of standard solutions that contain known concentrations of [Fe(SCN)]2+ and will determine

control group had a concentration of betacyanin of 0.09 µM while the -5⁰C test tube had a concentration of 23.5 µM‚ around 260 times more betacyanin leakage. Which suggests that there has been severe damage to the plasma membrane rendering it unable to perform its main function of being a selective barrier (Reece et al. 2011) leading to the flow of betacyanin out of the cell. While the concentration of betacyanin present in the test tube exposed to 40⁰C water was 1.13‚ the difference in concentrations

The Massacre of Sand Creek is a tragedy that occurred due to the greed of American’s. American’s have been trying to take away the Indian American’s land for years to expand the United States and it isn’t new for American’s to burst in on the Indian’s territory and remove their rights. This isn’t the first time the American’s have taken control of the Indian’s land for the purpose of pursuing something that is on or in their lands‚ such as gold in the Rocky Mountains. This gold found in the mountains

2.0 Kinematics of Linear motion is defined as the studies of motion of an objects without considering the effects that produce the motion. There are two types of motion: Linear or straight line motion (1-D) with constant (uniform) velocity with constant (uniform) acceleration‚ e.g. free fall motion Projectile motion (2-D) x-component (horizontal) y-component (vertical) 2 Learning Outcome: 2.1 Linear Motion (2 hour) www.kmph.matrik.edu.my At the end of this chapter

The Silver Lake Sand Dunes are a natural phenomenon that attracts more than a million visitors to western Michigan each year. Sand‚ sun and fun await you at the Silver Lake Sand Dunes nestled between the shores of Lake Michigan and Silver Lake in Oceana County. Tourism in this area dates back to the early 1920’s. At that time people usually travelled by train to the station located in Mears‚ Michigan. From there visitors and their trunks would be brought to the lake by horse and buggy. The area

In this Laboratory experiment‚ my lab partner Alexander and I were able to understand thoroughly the physical and chemical properties of salt (NaCl) and sand (SiO2). Followed by the right procedure we were able to design and test out the components of both NaCl and SiO2 in order to separate the unknown mixture that we were able to find out about. We were also given the task to provide the percent composition of the mixtures. Therefore‚ the separation of components among this experiment allowed us

EXPERIMENT 2: BATCH DISTILLATION AT CONSTANT REFLUX OBJECTIVE: To operate a batch distillation unit at constant reflux. To examine the change in top and bottom composition over time in a batch distillation. PROCEDURES: 1. Perform the general start-up procedures (Section 4). Refer appendix 1. 2. Record initial volume and refractive index of the liquid mixture in the reboiler. 3. Set the heater power to 1.5kW. 4. Set reflux timer to 10 second for set 1 and 30 second for set 2. ( Note: Set 1:

Vanessa Gale Formal Lab: Evaluation of the Gas Law Constant Dr. Monzyk Due 06/25/2012 Purpose: The purpose of this lab is to evaluate the gas law constant. The ideal gas law is represented as PV=nRT‚ where R represents the gas law constant. To determine R‚ we must find the other parameters‚ P‚ V‚ n and T through the experiment. Equipment and Materials: Large beaker Ring stand Clamp Copper wire 100 mL eudiometer tube Magnesium (Mg) ribbon M6 H2SO4 (Sulfuric Acid) Wash bottle

The Felis margarita‚ most commonly know as the Sand cat or the Sand dune cat‚ is a small‚ stocky‚ endangered feline. Its legs are relatively short and its tail is longer than average. Their fur is a pale sandy ocherous color with black and white markings differing between each individual. A broad head with pointy ears is an unique distinguishing factor of these desert hunters. (1) Sand cats are primarily found in true deserts‚ such as northern Africa and southwest/central Asia. Although there have
