compound that forms the toxic fumes produced when cadmium oxides are heated. It is an odorless white solid that is more dense than water. Cadmium nitrate is prepared by first dissolving the metal cadmium or its oxide, carbonate, hydroxide in nitric acid them immediately…

The experiment goal of the lab is to determine the concentration of acetic acid (CH3CO2H) in the commercial white vinegar brand. Procedure and Data Statement The complete experimental procedure is available in the General Chemistry Laboratory Manual for CSU Bakersfield, CHEM 211, pages 60-61, 64-65. Experimental data recored on the attached data pages 62-63, 66-68. Discussion…

Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask was weighed…

proteins work because they are essential to our health. Without proteins our bodies would not be able to form vital bodily components such as enzymes, and antibodies. A protein is defined as “large molecules consisting of one or more chains of amino acids in a certain order, determined by the base sequence of nucleotides in the base sequence of nucleotides in the DNA coding for the protein” (Medicine net). Insulins formula is C254H377N65O75S6 and its molecular mass is 5808 Da. When the protein…

Background: Acidic rain or acid deposition is predominantly caused by air pollution. Acid deposition in the form of gasses and microscopic particles, floating in the air, is called dry deposition. However, wet deposition is in the form of precipitation. As a result of chemicals being released from human productions, great amounts of sulfur dioxide and nitrogen dioxide are respired into the atmosphere, where rain and gas matter is polluted. Once both sulfur dioxide and nitrogen dioxide come in…

as: color changes, precipitates, and gases. Those that did not have reactions were also useful in the deduction process. To fully understand how this elimination process works, one must have a better conceptual understanding of aqueous solutions, acid-base reactions, precipitates, and the solubility rules. An aqueous solution is any solution in which water is the solvent. Simply put, it dissolves in water. In order for a substance to dissolve in water, it must either match or exceed the…

Using a specific example discuss a possible target for the development of anti-mycobacterial therapeutics ATP synthase is a main enzyme used to produce ATP in respiration of a cell. It makes use of a proton gradient in the mitochondrial cell membrane to generate ATP. By transporting protons back across the membrane, using ADP and a phosphate ion to create ATP. Normally most bacteria can gain enough ATP to grow optimally through substrate level phosphorylation, however it has been shown that M.…

The amino acid, homocysteine, is basically a cysteine with an added methylene bridge. Methionine, an essential amino acid, gives rise to homocysteine, a sulfur-containing amino acid, through the methionine cycle. Methionine is converted to S-adenosyl methionine (SAM) when an adenosine group from ATP is added on to activate methionine’s methyl group. SAM is a methyl donor that is a substrate used in many reactions. When it donates the methyl group, SAM is converted to S-adenosyl homocysteine…

recorded. Each Alka Seltzer contains the same three ingredients: 325 mg of Aspirin, 1000 mg of Citric Acid, and 1916 mg of Sodium Bicarbonate. Two of Alka Seltzer’s ingredients, Citric Acid and Sodium Bicarbonate (Baking Soda), were both placed into a beaker to see if both contents could cause a potential reaction. The final result was a non- occurring reaction. For a second test, both the Citric Acid and Sodium Bicarbonate were placed into separate, dry beakers. Afterwards,…

Key concepts Chemistry Chemical reaction Acids Bases Water Introduction Have you ever had a refreshing bath with bubbles or bath salts? What if you could use chemistry to create a bath-time treat that incorporated both fizzing bubbles and soothing salts? Such a combination does exist, and it's called a bath bomb. If you have never experienced one, these "bombs" become fizzy when they touch the water. Why? It is due to a chemical reaction taking place between different ingredients within the…
