600 mL of boiling water was prepared for use as a boiling bath with the use of a boiling chip. 2 grams of granular zinc and 2 grams of solid iodine. A setup consisting of zinc metal, iodine and boiling tube was weighed and tared, and 3 drops of 6.0 M acetic acid was added to 5.0 mL of water that had been deionized. This is acidic water that was then placed into the zinc, iodine and boiling tube setup. This is the key reaction for the experiment. The team waited for 15 minutes to let the reaction come to completion, with the boiling tube swirled until the completion of the reaction.
This solution is then decanted via the pouring of the solution to a 50 mL beaker with a boiling chip, weighed. 3 mL of water that has been made acidic and used to rinse the boiling tube This washings were also decanted into the beaker.
The water in the solid is then evaporated making use of a hot water bath. In the same way, the solution that had been decanted into the beaker was also rid of water via the use of a hot plate heated to 300 degrees Celsius. This led to the formation of the precipitate. The mass of the solid and the boiling tube was measured as well.
The observations with regard to the color changes are as follows. In the beginning the color is dark brown. The color transitions to a reddish hue, and converts to a light brown. The color then transitions to a light yellow. The color gradually transitions to paler and paler yellow, until in the end the color ...Download file to see next pagesRead More

... Attributes Of Fear in Achievement Research question: What damage can fear cause in one’s ability? A dispute can clearly be seen in the two texts on the impact of the word broken. According to Franklin, ‘broken’ can be used in two ways; first she talks about it being used positively, that is, a contestant was told by the judges that she looked good broken. This is a positive comment that used the word ‘broken’, as the judges praised the picture. It is also seen that the judges use ‘broken’ in a negative way, whereby, they say “You look like the broken Tin Man”. Franklin concludes, “sometimes looking broken is good; sometimes it’s not”. However, she dislikes the criticisms from the judges. On the other hand, Amy Tan dislikes... Attributes Of...

...Synthesis Scenario Auditory James should use Socratic learning method, where he should ask his what they know about symbolism, metaphor and simile. James must draw as much information from them as possible, filling gaps with his own expertise. Visual Visual tools can enhance and aid James in teaching, as then he can invite the students to participate in the lecture, which would keep them alert to the auditory environment as well. Kinesthetic James can adapt Kinesthetic learning strategy by asking students to use similes, metaphors and symbols in their daily conversations. He can initiate it by forming two teams, dividing up the class, and initiating a competition among them. This would make students active participants,...

Introduction of Synthesis of Zinc Iodide
...Your Full Your Experiment 4: Synthesis of Zinc Iodide Introduction The reaction of two or more reagents, elementalor as compounds, given the right atmospheric and physical conditions is commonly known as chemical synthesis, and is governed by the Law of Conservation of Mass. This law was proven by Antoine Lavoisier (1743 – 1794), and stated that matter can go through any physical or chemical reaction, but the total mass of the reactants and the products will remain equal (Rogers et al., The experiment aims to illustrate the Law of Conservation of Mass by reacting zinc metal and iodine to synthesize zinc...

...The Termites experiment The Termite’s experiment Terman, in the early 20th century, commenced an experiment based on belief that an individual’s IQ was a key predictor of his/her success in life. As such, his experiment sought to emphasize that one’s potential could be measured early in life. Consequently, Terman selected a group of children considered intelligent, and measured their IQ. The final selected group was named the “Termites” and had an average of 151 IQ. 35 years later, Terman’s assumption proved true with his gifted group conforming to his expectations (Terman, 1959). Other than being taller, healthier, physically developed, and socially adept, they showed greater success in life compared to others. As a matter... Termites...

...anywhere else, presence of such elements as Zn in excess in the river water is more dangerous since it reaches the livestock and humans directly or indirectly. A great variation in the behavior of Zn is also evident from the fact that while it is brittle at low temperatures, Zn becomes quite ductile and malleable at temperatures reaching anywhere between 110 and 115C. Just as it changes in its physical properties with temperature, Zn changes in terms of its effects on the environment when it gets in excess. This is a wonderful and very informative essay about the effects of Zn in the environment which is often considered as an element that cannot affect the environment in harmful ways. This is an important issue and needs to be...

...diets or when zinc was given intraperitoneally, and usually resistant mice became vulnerable when fed on a low-zinc diet.4 As for the helminth infections, animals with zinc deficiency either stored more worms or had protracted expulsion times. In H. polygyrus, trivial zinc shortage had little effect, even though severe zinc deficiency did raise the burden of a worm. In murine S. mansoni, zinc deficit resulted in reduced pathology without change in burdens of a worm. For Listeria, belated hypersensitivity reaction, T lymphocyte activation, was decreased but real bacterial clearance did not vary...

Dissolve 0.0026 mol of sodium borohydride in 4.5 mL of cold water in a second Erlenmeyer. 3. Add the sodium borohydride solution to the ketone solution dropwise. Use a Pasteur pipette, swirling the flask between each addition to disperse any cloudiness before adding the next drop. 4. Once the dropwise addition is complete, place a stirbar in the reaction flask and stir until a heavy slurry of precipitate forms. This should take between 30 minutes to 1 hour.
