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

electrons between the two metals in the metal sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also

: “The Negotiated Order of organizational Reliability.” | | Watson (2008)‚ “Organizational rules and hierarchies play a part of in the patterning of life in organizations but the overall organizational order is one that emerges out of the process whereby different groups make use of rules‚ procedures and information in the day- to-day negotiations that occur between them about what is about to happen in any given situation at any particular time.” Paul Schulman‚ in his writings on the Diablo

May 5‚ 2011 Suspect Apprehension: Perry Mason vs. Law and Order SVU [Introduction] Television crime and courtroom dramas have advanced in many aspects from the 1960’s through present day; visually and verbally. According to The Fifties Web‚ “Top ratings in the 1960’s‚” Raymond Burr’s Perry Mason was one of the top ranked crime dramas in 1961 and 62. In today’s era Law and Order SVU is among the favorites. Law and Order SVU and Perry Mason are both hour long crime dramas that investigate

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

Charles’ Law and estimate Absolute Zero In this IB Lab you will be assessed on the following criterion Conclusions and Evaluation Aim: Physics has many hundreds of laws and these can be tested in experiments to see if they are true. In 1787 the French scientist‚ J.A.C. Charles‚ published a law connecting the volume and temperature of gases. Your task is to see if you agree with his law. Another thing you have to consider is “ is my experiment accurate enough to prove or disprove the law ?“. It

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

Discuss the role of primary and secondary groups in the maintenance of social order and the emergence of deviance in Caribbean societies. Through the evolution of sociology as a discipline‚ several ‘big questions’ have dominated discourse in the subject. Such questions surround how social order is obtained and maintained in society as well as the factors that account for a movement away from the social order and engage in behaviour thought to be deviant. This discussion will seek to give an account
