My hypothesis was that pill bugs would be more attracted to a warmer environment in comparison to a colder one. However, the results of my experiment refute my claim. Initially I thought that the pill bugs would be naturally drawn to the warmer temperatures due to the fact that pill bugs are cold-blooded and need heat to survive but, for this experiment that was not the case. On average, there were 7 isopods in the cold chamber and 2 in the warm one. At the most there were 8 isopods in the cold chamber, whereas in the warm chamber, there was at the most 4.…
“See if you can guess what I am now … I’m a zit. Get it?” - Bluto Background: The purpose of the antiseptic lab was to show the effectiveness of multiple antiseptics: hydrogen Peroxide, Purell hand sanitizer, Water and Iodine.…
(UMN 2000); the NaHCO3 is an antacid, so also helps neutralise stomach acidity, relieving acid indigestion and heartburn.…
The goal of the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the flame test which had no discoloration when held in the flame, cation and anion tests which showed the existence of some halides like Cl, Br, and I, pH test in which the compound had a pH of 6, and the conductivity test which had an average value…
Dinitrophenol (DNP) is a compound most commonly found pesticides and food dye. When used as supplementation for weight loss, Dinitrophenol acts as an ionophore which allows protons to leak across the inner mitochondrial membrane thereby interfering with the electrochemical gradient in the mitochondrial which is needed for ATP synthesis. This disturbance in proton motive force used to drive ATP synthesis will result in the loss of potential energy as heat as the energy can no longer be used to form ATP efficiently. As a result, this loss of heat can be a factor behind why individuals taking DNP will excessively sweat. On the other hand, the need for ATP to function will force the body to compensate in the loss of ATP production by using fat…
Purpose Ibuprofen is one of the most common over-the-counter medications. It reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill.…
In this experiment Sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) was performed under reducing conditions to estimate the molecular weight of proteins within a sample. The protein sample was from the previous using anionic exchange chromatography to partially purify N-acetyl--D-hexosaminidase, Lab 3. The molecular weight was determined through the interpolation of a standard curve of proteins with a known molecular weight. The molecular weight of band 1 was determined to be 67,640 daltons and band 2 was 44,420 daltons, disproving the hypothesis that the molecular weight of the unknown protein sample was 28,000 daltons. The estimated molecular weight within this experiment for band 1 was close with literature values, which reported that under reducing condition the subunit molecular weights were approximately 63,000 and 56,000 daltons.…
The purpose of today’s lab was to determine how effective antacids are at neutralizing HCl. This experiment required us to place 3 antacids tablets into 3 Erlenmeyer flasks. Next we were required to add 50.00 mL of 0.500M HCl and five drops of phenolphthalein. Finally, we needed to titrate NaOH into the flasks. Each antacid brand required a different amount of NaOH in order for it to be completely titrated.…
In the first step of the experiment, m-toluic acid reacted with thionyl chloride to form the acid chloride derivative of m-toluic acid. In this reaction, the carboxylic acid is first converted into an acyl chlorosulfite intermediate, replacing the –OH of the acid with a better leaving group. The acyl chlorosulfite then reacts with a nucleophilic chloride ion, at which point the chlorosulfite leaves in the form of sulfur dioxide and chloride ion. The remaining acid chloride then reacts with diethylamine. Diethylamine is used in excess to neutralize the hydrogen chloride produced in the reaction.…
An antacid is composed of a basic chemical compound (the active ingredient), which is an essential component of a neutralization reaction. When this compound along with an acidic compound (HCl) dissociates, it react and form neutralized components such as water and a salt. This is an ideal mechanism of action for individuals who suffer from acid reflux or heartburn conditions because the excessive HCl that is found in the stomach can be alleviated by ingesting antacid tablets. This experiment explored the effectiveness of different antacids base on the number of HCl moles neutralized by the antacid. The data favor Alkalac as the most effective antacids base on moles neutralized per dosage.…
: The chemical formula of a compound will be determined using the mass of each individual element that is present in a weighed sample of that compound. The chemical formula shows the proportions of elements in a specific compound. This proportion is uniform to all samples of the same compound. Using the mass of each element, the moles of the element in the compound can be found and then compared to that of the other elements. This will create our atom ratio which will lead to our mole ratio.…
Antacids are weak bases that relieve heartburn by neutralizing small amounts of HCl in the stomach. When antacids are consumed bases such as OH- or CO32- are released and decrease the H+ concentration of a solution (the acid in the stomach) (Ferguson 2016). A neutralization reaction occurs when the base and HCl react producing a salt and water (Ferguson 2016). The purpose of this experiment is to test if the price of an antacid is correlated to it’s effectiveness.…
In this experiment three different environmental conditions that effect the rate of enzymes were tested: concentration, temperature, and pH levels; to try and find the absorbance rate of all three factors of enzymes. Each one being measured by a spectrophotometer every twenty seconds for 120 seconds. Eleven test tubes were numbered from one to eleven as well as eleven cuvettes. Each cuvette received one drop of guaiacol, three drops of hydrogen peroxide, and 2.8 mL of pH 7 buffer. Each test tube received different contents to measure the enzyme activity.…
In an enzyme catalyzed reaction, it is important that we have an enzyme, a substrate, and a product. Alkaline Phosphatase, the enzyme in our experiment, is an enzyme protein found in all body tissues especially the liver, intestines, and bone (U.S. National Library of Medicine). In order for body processes to carry on in a normal and efficient way, it is critical that this enzyme is present in the system of living things. Alkaline Phosphatase is important for the development of teeth and bones as well as keeping the tissues of the liver and kidneys healthy (Genetics Home Reference). The phosphatase in the enzyme is necessary to remove phosphate groups.…
Paracetamol is one of the world’s most beneficial and resourceful analgesic and is widely used in present day. An analgesic, can be defined, as a chemical compound that relieves pain, reduces fever and inflammation. It works by hindering the enzyme cyclooxygenase which acts a catalyst to convert fatty acids to prostaglandins. Prostaglandins cause pain and inflammation to peripheral and central points in the nervous system2. Paracetamol, or Acetaminophen is created by the synthesis and preparation of an amide.…
