Fruit Spoilage Lab Abstract: The purpose of this lab is to see if lemon juice has an effect on fruit turning brown. When fruit is exposed to the air, it turns brown so the target of the lab was to try and prevent discoloration of the fruit. Using lemon juice and water, apples and bananas were tested to find if the chemicals really did prevent brown coloring from appearing on the fruit. With the lemon juice as the independent variable and the apples and bananas as the dependent variable, the…

Discussion of results: Multiple tests were done in order to identify and then confirm the identity of an unknown substance. The tests done to identify the compound included preliminary tests, solubility tests, and testing for anions and cations. In order to confirm the identity found, reactivity tests were then completed. The first test performed was a preliminary test that simply showed that the unknown compound was a powdery, white solid with no smell. A qualitative solubility test was…

(DeLoney-Marino CR, 2013) Vibrio Fischeri is a heterotroph and has the ability to be anaerobic and aerobic which was determined through genome sequencing and chemical assays. One of the ways in which it is able to grow anaerobically is by using mixed-acid fermentation. (Ruby et al. 2005) Vibrio Fischeri is also oxidase positive. Location: Vibrio Fischeri is found in shallow marine environments and has a symbiont relationship with certain squid and fish (see Figure 1). Vibrio Fischeri stops the…

Phosphorus is an element with the atomic number 15 and is described by the symbol P. Phosphorus was found in 1669 by a man named Hennig Brand. Brand was testing urine samples when he came across a weird substance now known as Phosphorus. Phosphorus is stored in the small intestine, but is mostly found in your bones. Phosphorus can be helpful in so many different ways. Phosphorus can be found in food such as meats, peas, and different types of dried beans. Phosphorus can also be used in fireworks…

in USA and is mainly produced by the Solvay process: NaCl + NH3 + CO2 + H2O NaHCO3 + NH4Cl Sodium bicarbonate, when exposed to an acid, releases carbon dioxide and water: NaHCO3 + HCl NaCl + H2O + CO2 (gas) Above 70°C, it gradually decomposes into sodium carbonate, water and carbon dioxide: 2 NaHCO3 Na2CO3 + H2O + CO2 It is used as an antacid to treat acid indigestion and heartburn. Sodium bicarbonate is also used to absorb moisture and odours; an open box can…

Activity 2: Chemistry In a Bag With Chemistry In a Bag, students learn the difference between a physical change and a chemical change and how changes can either be endothermic or exothermic. Set-up: Each group of four students will need 1 canister filled with calcium chloride (CaCl2), 1 canister filled with sodium bicarbonate (NaHCO3), 1 dropper of phenol red, a set of measuring spoons, a measuring cup, a portion cup, four pairs of goggles and four sandwich bags. Make sure there are paper…

Introduction Termites, Isotera, are known to react to the exposure of the chemical substance found in ball point pens. Naturally, termites will follow any trail made up of pen ink. This specific observation was tested and carried out by Sim et al. They “investigated how termites select the direction of movement at an artificially-designed branching node, by making chemical trails on filter paper, drawing lines using a ballpoint pen which contained the chemical substance that induces the termite…

The land application site has been in use since about 1973 for the treatment and disposal of cheese processing effluent. Prior to that time, the site was used for irrigated agriculture. Swiss Village Cheese Company originally operated the facility in 1973. From approximately 1991 until 1999 the facility was operated by Simplot Daily Products. Sorrento Lactalis, Inc. purchased the plant in early 1999 and continues to operate the facility today. Currently both treated wastewater and freshwater…

transfers the sulfane sulfur to other receptors (eg. Cyanide) by ST enzyme, while the thiosulfate is converted to sulfite (Xin et al., 2016). As described above, the sulfane sulfur consumed may also be derived from the metabolism of intracellular amino acids (Ida et al., 2014) or self-oxidation of H2S (Chen and Morris, 1972) or catalysis of enzymes (Xin et al.,…
