    calculation, the experimental data as well as the chemical reaction of calcium hydroxide was used for all calculations. The chemical equation is displayed below: The first experiment determined the molarity of OH- and Ca2+, the Ksp and the ΔG for saturated calcium hydroxide at 21°C. In order to determine these values, the experimental data as well as the chemical reaction of calcium hydroxide was used. The molarity of OH- and Ca2+ was discovered to be 0.028 M and 0.014 M respectively. The Ksp was found to be 1.144 x 10-5 and ΔG was discovered to be 27.470 KJ/ mol. The second experiment determined the molarity of OH- and Ca2+, the Ksp and the ΔG for saturated calcium hydroxide at 60°C. The molarity of OH- and Ca2+ was discovered to be 0.029 M and 0.014 M respectively. The Ksp was found to be 1.316 x 10-5 and ΔG was discovered to be…

    Evidence and Analysis: The literature Ksp for calcium hydroxide is 5.02×〖10〗^(-6), which is a relatively large Ksp value. This goes against the “rules of solubility” that labels calcium hydroxide as insoluble. According to the “rules of solubility”, calcium hydroxide should not be soluble in water; however, our results reveal that it does have some degree of solubility at standard conditions. We know this because we started with an initial concentration of calcium hydroxide and no concentration…

    Calcium hydroxide (Ca(OH)2), universally referred to as lime water or slaked lime is formed by reacting hydrated lime (calcium oxide, CaO) with water (H2O)[1] CaO (s) + H2O (l) ⇌ Ca(OH)2 (aq) (ΔHr = −63.7 kJ/mol of CaO) Calcium hydroxide is an economically favorable alkaline reagent to neutralize acid as it yields 2 moles of (OH)2 for every 1 mole of Ca(OH)2 (which is slightly soluble in water) when compared to sodium hydroxide [1] and it may separate from the solution ‘constant agitation must…

    used in research of other possible fuels by finding the cost to produce it and comparing it to the amount of energy it will provide to find out if it is a worthwhile investment. The main objectives of this lab are to find the energy changes in reactions two and three then using two and three find the ideal reaction one’s change in energy. The general experimental design is that using a calorimeter you would first find the change in energy of calcium carbonate reacting with two hydrochloric acid…

    freight train derailed causing a possible spill of the chemical contents it carried. According to the District of Columbia Fire and Emergency Medical Services department (DCFEMSD), the derailed train in northeastern Washington DC resulted in the leakage of hazardous chemical material by three cars (Washington, 2016). The total amount of cars sent outside the railroad in the derailment incident was however, confirmed to be 14 according to CSX. The possible extent of the hazardous spillage had not…

    1. What is FOP? Fibrodysplasia Ossificans Progressiva is a rare genetic disease in which a person’s bones will begin to form into the muscles, tendons, ligaments, joints and connective tissues. Overtime the development will restrict a person’s movement. It has been described as turning a person into stone because their body is essentially encased by a second skeleton. 2. What are the initial symptoms? Symptoms of Fibrodysplasia Ossificans Progressiva, include: an infant being born with short,…

    Those who were against milk generally said it was because they thought it was unnatural and therefore unhealthy. Sarah Adams believes that milk is not good for us because, “calcium doesn't synthesize into our bodies properly”. In her stated opinion Sarah must assume that the only reason we would drink milk is for the calcium we would supposedly absorb. Her assumption seems reasonable. When she was a kid growing up the popular idea…

    study, this surgery caused a 54% increase in hip, spine, and wrist fractures in postmenopausal women” (Taylor, 2009). Another possible cause of osteoporosis is low testosterone in men. “Men need both testosterone and estrogen for bone health” (Taylor, 2009). Men convert testosterone into bone-preserving estrogen (Taylor, 2009). Hormone imbalances can play another role in osteoporosis. Parathyroid hormone and growth hormone help orchestrate how well the bones use calcium and when to build up bone…

    Osteomyelitis Anoimalo S. Matagi Alaska Career College Abstract Osteomyelitis affects about two out of every 10,000 people (Cleveland Clinic, 2016). A possible reason as to why two of 10,000 people are affected is their lack of understanding to how to treat and prevent osteomyelitis. For example, those who are not aware of how osteomyelitis and how it effects the bone, as many organisms (most commonly staphylococcus) travel through the blood stream and can cause a bone…
