Introduction The purpose of this experiment was to determine the rate law graphically from the rate of disappearance and the x y values also the specific rate constant (k). Activation energy was also determined‚ and the effect of catalyst was evaluated in the reaction between peroxodisulphate ion S2O82-‚ and iodide ion‚ I-. S2O82-(aq) + 3 I-(aq) --> 2 SO42-(aq) + I3(aq) The general expression for the rate law‚ given this overall reaction‚ is: rate of disappearance of S2O82- = k[S2O82-]m[I-]n

Role of Folic Acid in Neural Tube Defects | A genetic‚ environmental‚ and nutritional approach to better understanding of abnormal conditions | | Darshak Joshi | July 6th‚ 2013 | | Introduction Human birth defects‚ today‚ continues to be a highly investigated research. There remain many convoluted combination of genetic and environmental factors that can cause birth defects. While some conditions are easily repaired through surgery‚ neural tube defects (NTDs) present problems

“Test-Tube Burgers” One summer when taking a trip to a friends country house for a weekend I took on the challenge of being a vegetarian. My friend‚ an only child‚ had been raised a vegetarian by parents who were also vegetarians; never once in his life had he eaten meat. Although the family was tolerant of whatever I did‚ I decided this was an opportunity to try it for myself and see what it would be. At the end of the few days I found it quite easy‚ although in reality I did not consume nearly
Free Meat Vegetarianism Ethics of eating meat
Recently a scientist by the name of Mark Post helped create a “test tube” beef burger. The burger was grown in a solution of nutrients and cost about 330‚000 dollars to make. The burger was created by taking muscle cells from a cow and growing them into tissue. The meat had to be dyed to make it look like real beef. The meat contains no fat and is disease free. The meat was made in the Netherlands at Maastricht University. It was served to two volunteers and was flavored with egg powder and bread

Final Exam Essay Throughout this course I have gained specific knowledge through reading two different books and short stories out of another‚ I had the chance to understand an anthropologist’s point of view. Three ways that cultural anthropologists provide a unique and informative perspective on the social issues they study are: Looking at the circumstances through a participant perspective (avoiding ethnocentrism)‚ historical context‚ and concept of culture. In both Veiled Sentiments and In

Results and Discussion 2.5.1. Morphological characterization of hollow fiber capillaries from FESEM images The longitudinal view of the hollow fiber is presented in Fig.3 (a). The outer surface was further magnified to look into the pore details in 5KX and 25 KX magnification‚ are shown in Fig.3 (b) and (c).The image of the hollow surface revealing the cut surface showing the inner layer of the hollow fiber are shown in Fig.3 (d). The fine structures of the fibers ‚ shown in Fig.3 (e) and (f) resembles

Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges

Induction and Faraday’s Thursday‚ October 25‚ 2012 Lab Report 6 Introduction and Faraday’s Law Objective: In this experiment‚ Faraday’s law of induction will be investigated. Theory: Faraday’s law of induction states the induced emf or voltage in a coil is proportional to the rate of change of magnetic flux through a coil‚ this is shown blew: Ƹ= -dɸ/dt Equation 6.1 The flux of the magnetic field is defined and the following: ɸ=BAcosΘ Equation 6.2

Chest Tube Insertion‚ Infant A chest tube is a thin‚ flexible tube that is inserted into the space between lung and chest wall. Air or fluid can collect in this space and cause infants to have breathing trouble. Infants at risk for this complication include those who: • Have lungs that are not fully developed at birth. • Breathe in stool during the birth process (meconium aspiration). • Need to be on a machine to help them breathe (ventilator). • Have surgery on the heart or lungs
