imply that there was a mechanical error that occurred, thus, also tampering with the progression of the chemical reaction. The wide melting point range of 165 C-169 C denote the impurity of the acetaminophen product. INTRODUCTION Chemical synthesis is an imperative technique most relevant to organic chemists. Synthesis employs a succession of chemical reactions by using pre-existing structures to make new and functional ones. A combination of lab techniques

Organic Dehydration Reactions Dehydration reactions, also known as Zimmer’s Hydrogenesis , are a type of condensation reaction involving the loss of water through elimination reactions. Dehydration reactions are one of the most fundamental organic chemistry reactions. They are also one of the oldest studied reactions. Following the same basic reaction steps as E1 reactions they are used in a variety of applications such as converting alcohols to ethers, converting alcohols to alkenes, converting

The Chemical Weapons Convention (CWC) defines chemical weapons as “Any toxic chemical or its precursor that can cause death, injury, temporary incapacitation or sensory irritation through its chemical action” (Organisation for the Prohibition of Chemical Weapons, n.d.). Chemical weapons have been around for a long time since ancient times, in fact some chemical weapons such as chlorine were frequently used during World War I (War of nerves, 2006) (Pitschmann, 2014). Over the years with the increase

was an enzyme that helped catalyze the oxidative coupling of vanillin to produce divanillin. The role of the enzyme is to increase the rate of the overall chemical reaction to reduce reaction time, therefore making the reaction process faster. The Horseradish peroxidase Type 1 achieved this by decreasing the activation energy required for a chemical to react, thus allowing the reaction to process through a lower activation energy, which increases the reaction rate and makes the reaction faster. Reaction:

Discussion The experiment investigated the relationship between temperature and the rate of reaction for the reaction of iron (III) nitrate with sodium thiosulfate. The results show that the rate of iron (III) reacting forming iron (II) increases as the temperature of the solutions increases. Table 1 shows that when the temperature of the reactants is 4℃, it takes 54.173 seconds for the reaction to occur to the stage that the cross to appears. The time taken for the solution to reach the same transparency

The goal of this experiment was to use conductivity to evaluate the number of ions in a chemical equation to confirm that the Law of Conservation of Matter is true both in theory and practice. The original hypothesis was that the experimentally determined ions and number of moles would indeed give the same results as the Law of Conservation of Matter, and that the predicted volume of acid needed to completely react with barium hydroxide would be 12.5 mL. This hypothesis has been proven in that the

Abstract: The main purpose of this experiment was to purify the steroid hormone, Cholesterol, by Bromination. This process was achieved by the electrophilic addition reaction to a natural product (Cholesterol dibromide). After adding the designated amount of the white powdered cholesterol and the reddish brown solution of bromine to the Erlenmeyer flask, the mixture turned to a bright yellow color then it was chilled in an ice-water bath, allowing crystals to form. Finally, the vacuum filtration

explanation of this relationship is Le Chatelier’s Principle (Fondriest Environmental 201410), which explains how changes in concentrations, pressure, and temperature alter the equilibrium of a reaction. Increasing the temperature favors the endothermic reaction, meaning if the forward reaction is exothermic, then the new equilibrium has more reactant than the old one, and vice versa in endothermic forward reactions. The opposite occurs when decreasing the temperature and the exothermic reaction is favored

During part A of the experiment, the solution and LabQuest was prepared. The 300 ML solution of HCL solution was prepared through the addition of 200 ML of deionized water and 100 ML of 6 M HCL. This solution was labeled “2 M HCL”. The solution was stirred with a glass stirring rod. Next, a 150 ML of 3 M NaOH was prepared through the addition of 50 ML of deionized water and 100 ML OF 3 m NaOH solution. This was labelled “2 M NaOH”. The solution was stirred with a glass stirring rod. It was important

1.4 Elements of housebreaking In South African law, housebreaking consists of five elements. These elements are a crucial part of the crime, the reason is simple: all of the elements must be present in order for a perpetrator to be guilty of housebreaking with the intent to commit a crime. 1.4.1 Breaking Breaking refers to a perpetrator that displaces some obstruction, which forms part of the premises, in order to create an entry onto that premises. Breaking can take effect when a lock, window
