    Experiment 4a

    We placed the zinc inside the beaker and slowly poured the hydrochloric acid into the beaker. As soon as the acid entered the beaker, there was a sizzling sound and bubbles started to form as we add more of the substance in. When the bubbles were forming, we could see a steam of gas coming out of the beaker. After 10 minutes, we noticed bits of zinc were floating on top of the hydrochloric acid and lining the beaker. I lifted the beaker and felt the bottom and it felt warm, which meant the reaction was still happening. After 20 minutes, we added water into the zinc and hydrochloric acid to stop the reaction and we observed a slight cloudy colour (still clear) forming as we slowly pour the water in the beaker.…

    The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns, in part 1, Ag+, Pb+, and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2, the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate.…

    Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process, called substrates, are converted into different molecules, called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts, enzymes work by lowering the activation energy for a reaction, thus dramatically increasing the rate of the reaction. As a result, products are formed faster and reactions reach their equilibrium state more rapidly. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts in that they are highly specific for their substrates. Enzymes are known to catalyze about 4,000 biochemical reactions.…

    INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose, Indole Production, and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous in his stool. The patient had no pain but mild discomfort during bowel movements. The doctor noted inflammation of the lining of the rectum. The doctor removed a tissue sample for examination and referred the patient to a gastroenterologist for a barium xray and colonoscopy. While utilizing the methods stated above, the bacterium found was a facultative anaerobe due to the Gram Negative Rods, fermentation, and the production of indole. The specific Gram Negative Enteric Bacilli was Shigella dysenteriae. There are many reasons for knowing how to control bacterial growth as well as such as antimicrobial drugs, which assist the body’s defenses against pathogens. Microorganisms are capable of causing infection or spoilage. Controlling bacterial growth is important in poultry farm businesses that use equipment to decontaminate processing plant fluids before disposal. During quality control and safety evaluations, bacteria growth that needs to be controlled can be found. While controlling bacterial growth, clusters of Gram Positive Cocci were found. It was found some ways to control bacterial growth were disinfection, sterilization, antisepsis, sanitization, moist and dry heat, filtration, and radiation; just to name a few. The specific method used for control depends on various circumstances.…
