Experiment 14: Preparation of 1-Bromobutane Goal: To prepare 1-Bromobutane by the SN2 reaction from 1-Butanol with Sodium Bromide and Sulfuric Acid. Mechanism: Procedure: 1. Place 27g of NaBr‚ 20mL of n-butyl alcohol‚ and 30mL of water into a 250mL round bottom flask. 2. Put the mixture in an ice-water batch and cool briefly‚ then slowly add 23 mL of conc H2SO4 while stirring with a magnetic stirrer. 3. Place a water-cooled condenser and heat the flask until the mixture boils while

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

the hot water from combining it with the cold water. As discussed in a page titled Heat Capacity2‚ the heat capacity is defined as the amount of heat it takes to raise the temperature of a substance by one degree (in this case C). In the experiment performed in lab‚ the heat capacity of the calorimeters was calculated by subtracting the heat gain from the heat loss and then dividing that by the difference in the temperatures between cold water and the combination of the hot and cold water‚ . The heat

Intercontinental University Aspects of Psychology Individual Project # 2 Experiments and Adaption July 30‚ 2012 ABSTRACT This paper is explaining five experiments; the process and results. It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed. Before starting the four experiments‚ I had to remember that I had to keep in mind that there are five

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature
