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

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

soil property. These two tests are the falling head permeability test and the constant head permeability test. Which test is used depends upon the type of soil to be tested. For soils of high permeability (sands and gravels) a constant head test is used. For soils of intermediate to low permeability‚ a falling head test is used. As we were testing sand we used a constant head permeability test. By carrying out the constant head permeability test we can determine the coefficients of permeability of

In the ethnography‚ “Mother’s Love: Death Without Weeping” by Nancy Scheper-Hughes‚ the author discusses her fieldwork of observing the poverty-stricken mothers who refuse to care for their sickly children in Northeast Brazilian shantytown‚ Alto do Cruzeiro. She questioned the kinship system on the severe hardship of poverty in relation to a bond between a mother and infant. Two theoretical perspectives that strongly portrays in the article is cultural materialism and individual agency‚ as cultural

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:

P5. Homeostasis is the process by which a constant internal environment is maintained by our body. For instance‚ this means that in our body‚ temperature‚ blood sugar levels‚ etc must be kept within a narrow range even when we are in a freezing climate‚ or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment‚ for example‚ detects temperature change. Then‚ after the receptor

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.

The poem touches me and leaves me with a feeling of achieving a higher greatness. The poem is just this. “Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light‚ not our darkness that most frightens us. We ask ourselves
