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.,…

The tart, tangy taste of apple cider vinegar (ACV) has been treasured since at least 400 B.C when Hippocrates first discovered the natural anti-bacterial and anti-microbial properties that this inexpensive liquid contains. Not only can it kill germs, but it is good for your health! Many common household cleaners are full of toxic chemicals that can make people very sick and even lower their I.Q., but ACV is all-natural. Not all types of ACV are made the same though. Some are full of residual…

1. The first part of the second experiment went according to the alternative hypothesis. The 200% saline water moved below the 100% saline water to create a layer. It did not mix with the 100% saline water or tap water. On the other hand, the second part of the second experiment did not support the alternative. Instead of moving above the 100% and 200% saline water and tap water, the 35% saline water remained at the bottom. However, it did try to move up. The reason the 35% saline water did not…

alike when they make contact with acidic acid. Being that they become extremely reactive with the acidic acid, forming consecutively larger bubbles until the solute (being Sodium bicarbonate) had completely dissolved in the acidic acid. Using the universal indicator it can be observed that the Unknown substance or Sodium bicarbonate had both became a chunky paste, which turns into a dark green colour which signifies that it is a moderately neutral-weak acid. Finally, when comparing the Unknown…

Martha Garcia November 10, 2017 Chemical Weathering Background Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is…

the residues from the manufacture of sea salt at Montpellier. He liberated the element by passing chlorine through an aqueous solution of the residues, that contained magnesium bromide. Distillation of the material with manganese dioxide and sulfuric acid produced red vapours, which condensed to a dark liquid. The similarity of this procedure to that for making chlorine suggested to Balard that he had obtained a new element similar to chlorine. German chemist Justus von Liebig supposedly had…

Apple cider vinegar is a popular and useful health aid. Diabetics often take a swig to help control their blood sugar. Trying to lose a few pounds? Many believe that the consumption of apple cider vinegar leads to reduced belly fat, lower triglycerides, and weight loss. According to Doctor Oz, it is an excellent way to control dandruff. With so many uses, it is a staple in many homes, including my own. In fact, I bought the largest jug I could find, but I had never considered the shelf life of…

In this experiment, the components of “Wellactin A” were separated into sucrose, an unknown carboxylic acid, and an unknown organic neutral compound. The unknown compounds were identified by their melting points and the percent recovered was calculated. First, the sucrose was separated by dissolving the organic acid and the organic neutral compound in diethyl ether. 104.9% was recovered, so that means the sucrose was not entirely pure. The sucrose could have been contaminated by another…
