successfully synthesis the reactant to the product‚ NaBH4 was used as the main reagent to reduce the carbonyl double bond. One believes the formation of isoborneol was successfully due to the product’s percent yield‚ IR‚ and melting point. During the lab‚ .077 grams of isoborneol was yielded from the camphor reduction. In result‚ .077 g compared to an theoretical yield of .102 g equaled an overall 75% percentage yield. Considering the product yield was only a quarter shy of a 100% yield‚ provides strong evidence

not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

interface Non-linear springy objects (rubber bands) Two rectangular weights of ~0.5 kg each to change the mass of the system Procedure: The lab experiment was done in two parts. Part 1 of the experiment was done by 2 different methods. Method 1 was with a force sensor‚ springs‚ and a weight hanger in which masses of 100 gram increments were added (up to 600 grams). A force vs. displacement graph was created and the slope of the graph was recorded. By method 2 the force sensor was tare with a 1 kilogram

Abstract In this lab we separated components of a simulated preparation‚ panacetin and making use of its acid base properties. To obtain such a pure compound‚ the compound we want must be separated from its other natural components‚ which can be done by manipulating physical and chemical properties. Panacetin contains sucrose‚ aspirin and an unknown which can be acetanilide or phenacetin in which phenacetin was created and weighed. Introduction In this lab our basic goal was to make the

Organic Lab Trial 1 Trial 2 Trial 3 Observations We added the 30ml of warm water with 4.7 grams of borax powder in to the cup labeled ‘Borax Solution’ and also added a few dots of green food coloring. We then stirred it until all the solutions were completely mixed. When this happened the borax and water turned into a watery green solution. then we added 15ml of glue in the cup labeled ‘Ball mixture’ and added the mixture we made

advertisements that can impact us negatively or positively. When we look at an advertisement we tend to look at what is being advertised but if we looked more closely‚ there is always a story that is trying to be told to us. Several advertisements can bring negative stories that can be sometimes sexist. Sexist ads portray women as objects in order to convince consumers to buy the product. Other ads tend to portray the perfect women that each time seems to become impossible to achieve. Kilbourne and Mernissi

For this lab multicolored sprinkles were used to represent small particles. Because of the variation in color these particles used created a mixed culture and therefore are it was not a pure culture.

Introduction In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role‚ if any‚ that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose‚ lactose will separate into galactose and glucose‚ as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions‚ and
