Abstract: The purpose of this experiment was to find the amount and percent of water in a hydrated salt. Hydrated salt contains water molecules chemically bound to it while anhydrous salt is a substance that fire can readily remove the water molecules. Using the gravimetric analysis method, the sample salt was measured, heated, and was measured again after cooled down to room temperature; this procedure allowed the weight of water lost in the salt to be obtained. After two trials, the water in the
Connects: The Long Chain Reflection In the movie, I thought the story of the chain of events leading to the various chemical discoveries was very interesting. For most of the discoveries, It was not a straightforward process in which the intention behind the formation of the new product coincided with its practical use. There were a lot of discoveries made for one purpose, but ended up being implemented for a different purpose. Not only that, but there were several products which led to subsequent
from the neutral fertilizer solution one will need a filter to remove solid crystals of fertilizer. The name of the fertilizer can be easily predicted based on the name of the acid and the alkali used in the process. For example, nitric acid and ammonia will be needed to make ammonium nitrate. 2. MAIN PART 2.1 Fertilizer Placement by Type Nitrogen fertilizer Placement decisions should maximize availability of nitrogen to crops and minimize potential losses. As a plant’s roots usually do not grow
The nitrate-nitrite-NO pathway can have beneficial health effects. Dietary nitrate has been shown to improve the mitochondrial functioning as it affects proteins involved in uncoupling contributing to an increase performance in exercise. The pathway begins through consumption of dietary nitrates that are converted to nitrites by bacteria in the oral cavity. The reduction of nitrates to nitrites may affect hemoglobin. Excess nitrites added to deoxygenated hemoglobin will oxidize to form methemoglobin
The sodium cation did not have an effect on pH. We tested sodium acetate, sodium carbonate, sodium bicarbonate, sodium bisulfate, sodium bisulfite, sodium chloride, sodium citrate, sodium formate, sodium iodide, and sodium hydroxide. The pHs of these compounds ranged from 1.25 to 13.00, which were sodium bisulfate and sodium hydroxide, respectively. Sodium bisulfite and sodium carbonate had average measured pHs of 4.24 and 11.13, respectively. Since this range is so wide, we can conclude
Bismuth(III) metal is relatively inert, soft and malleable. The world production of bismuth(III) is about 5000 tones per year [1]. Bismuth is seen as the least toxic heavy metal for human being and is widely used in medical applications for its good antimicrobial properties. Bismuth(III) compounds are used in cosmetics, pigments and a few pharmaceuticals, nearly 70% of the production being used for this purpose. Bismuth(III) compounds have been used in medicines for more than 200 years in variety
The two primary metabolic processes nitrates undergo are through the entero-salivary circulation pathway and the nitrate-nitrate-NO pathway (Nitrate/Nitrite Toxicity 2013: Biologic Fate of Nitrates and Nitrites, 2013). Inorganic nitrates and nitrites consumed through food and water are first reduced in the oral cavity by bacteria present on the tongue. This reductive activity converts nitrates to nitrites where it can further be metabolized through the gastrointestinal tract. After conversion of
Why is Lisinopril used? Lisinopril is used in the treatment of heart failure, hypertension (high blood pressure), and to assist in the improvement of survival in patients who may have suffered from a heart attack. It is in the class of Angiotensin-Converting Enzyme (ACE) inhibitors. This medication works by reducing specific chemicals that squeeze the blood vessels, so that the blood can flow smoother and the heart can pump the blood more effectively and efficiently.

From the time the Graham Fire and Rescue crew got the call, it took them three minutes to arrive on scene at the Powell residence fire. Upon arrival, the department’s assistant chief stated that the fire was “burning hot” and already through the roof (Reavy, 2012). Based upon statements made by the social worker and the short amount of time in which it took first responders to arrive on scene, the incipient stage of the fire could not have lasted more than a minute. The social worker claimed to
On 05/02/2018 the Merced County fire department responded to a fire on the property of 15476 August Ave, in the township of Delhi. Fire department personnel arrived on scene and located a large junk pile on the north east corner of the property was in flames. In the course of attempting to control the fire, firefighters opened up an adjacent 30 foot white Aly Aljo trailer with Brown Orange &Tan stripes. Firefighters noticed a large amount of marijuana inside the trailer and contacted the Merced
