Personal Behavior Change For this paper I decided to take a second and evaluate my life and think about what were some of my current lifestyle habits and behaviors and which out of these habits would I like to change. After sitting down and evaluating all of my main habits I categorized them into groups of which ones were helping to lead me to a long healthy lifestyle and which ones were likely to lead me to an unhealthy life and lifestyle. After narrowing these unhealthy habits down to my top three I decided to focus this paper and my attention on my current nutrition and most of all on my negative eating habits. After evaluating my lifestyle and all of my unhealthy habits I felt that my current nutrition level and eating patterns were in need of the most improvement and change. One of the reason’s why I felt my nutrition needed to changes is because nutrition is a huge part of a healthy lifestyle, the way that we eat and what foods we consume can have a huge impact on our everyday lives. Nutrition plays a huge role in multiple facets of a person’s life energy, health, skin, weight, confidence, and more making having a good control on your eating habits extremely important. How we eat over the years and what foods we routinely choose to eat can eventually have a lasting effect on use and what we consider to be most appealing and appetizing at any given moment. Having these craving and routine habits makes eating, diet, and nutrition both a behavior and a lifestyle choice that can be changed over time with help from the theories learned in this class. I felt that with the behavior that I was trying to change the Transtheoretical Model (TTM) would be most effective for me. The reason I decided to choose this model was because... ... currently in. By reassesses your progress and where you are currently you allow yourself to keep from relapsing and falling from one stage back down to another. In this particular article they reassessed their participants commitment and current stage every six and twelve months (Geoffrey 2012 p.256) I feel for me moving forward reassessing my current commitment every three months would be most effective. Reason for this is at the 60 days is when you need to start making a move from preparation into the action stage, also after 6 months of being in the action stage you can consider yourself within the maintenance stage. By evaluating every three months I can have a solid idea of when I have left my preparation stage and finally entered action and after two assessments in the action stage I can start to consider myself firmly within the maintenance stage of change.

Chemistry: Displacement Reactions Essay

Objectives: 1. Learn how to determinate the percent composition 2. Learn how to get the percent using oxidation reduction and double reactions 3. To become more familiar with the use titration techniques 4. To learn how to get the salt out of an quimical Background: To develop and utilize procedures to determine the percent composition, of ZnCI2. As well titrating with NaOH solution. After all the experiment we got hta salt witch we weighted and we got our results. Experiment reactions: .33w of Zn(OH)2 x moles Zn(OH)2/m. moles Zn(OH2) x 1molZnCI2/1 mol Zn(OH)2 x g molZnCI2/1 mol of ZnCL2 = .4531 grams of ZnCI2 .4531g of ZnCl2 x 1 moles ZnCI2/m. moles ZnCI2 x 1molZn/1 mol of ZnCI2 x 65.39 of Zn/1 mol Zn = .2174g Zn Materials needed: Scale Burette Beaker Spatula Erlenmeyer flask Prenolpthen (color indicator) ZnCL2 NaOH Tube Vacuum Paper filters Rubber base Questions: 1. What is the weight of a post 1982 penny? 2.5 grams 2. What is the percent copper and zinc in a post 1982 penny? 97.5% of zinc and 2.5% of copper 3. How many grams of copper and zinc are in a post 1982 penny? 2.44grams of copper and 0.0625gramss of zinc 4. How many moles of copper and zinc are in post 1982 pennies? 0.0383moles of cooper and 0.000955moles of zinc 5. Write a balanced reaction of zinc with HCl. Zn (s) + 2 HCl(aq) ====> Zn+2(aq) + 2 Cl-(aq) + H2(g) Reaction: Zn(s) + 2 H+(aq) ====> Zn+2(aq) + H2(g) 6. How many moles of HCl are needed to react completely with all of the zinc in a post 1982 penny? 7.46 x 10-2 mol HCl 7. In a procedure developed to determine the percent zinc in post 1982 pennies, 50 ml of an HCl solution was used to react (dissolve) all of the zinc in the penny. To ensure complete reaction, the solution contains twice as many moles of HCl that is actually needed. What concentration of HCl should be used? M=2.984 7.46Ãâ€"10-2 mol x 2 = .1492mol H 8. In the scenario described in problem 7, what is the amount (in moles) of excess (unreacted) HCl in solution? .1492 moles used .0746 needed .0746 moles HCI unreacted 9. How many moles of NaOH would be needed to completely react with all of the excess HCl determined in problem 8? .0746 moles HCI reacts with .0746 moles of NaOH 10. As described in problem 7, a procedure was developed to determine the percent zinc in post 1982 pennies. In that procedure 50 ml of an HCl was used to react (dissolve) all of the zinc in the penny. To ensure complete reaction, the solution contains twice as many moles of HCl that is actually  needed. To determine the percent zinc in the penny, the excess (unreacted) HCl was titrated with NaOH. Determine the concentration of NaOH needed if you want to use approximately 25 mL of NaOH to titrate the excess HCl. M = .0746 moles of NaOH/.025L NaOH M = 2.984 11. Write the balanced chemical reaction of zinc with HCl (same as problem 5). Is the product of this reaction soluble in aqueous solution? Yes soluble Zn(s) + 2HCI (aq) = ZnCI2(aq) + H2(g) 12. Write the balanced chemical reaction of the product of the reaction described above (problem 11) with NaOH. Is the product of this reaction soluble in aqueous solution? ZnCI2 + 2NaOH = Zn(OH)2+ 2NaCI Zn(OH)2 = low solubility Expected results: Our expected results are to obtain the pink cluster in the solution while titrating. This way after taken more steps we while maybe be able to find some salt. Steps to do: *In the first part of this experiment we are going to dissolve the zinc core of a penny *After that we leave the copper covering intact *We also by putting four notches in the coin using a triangular file and placing the penny in 50ml of a predetermined concentration of HCI overnight *After that we are going to determinate the concentration needed to add 2 times the number of moles of HCI needed in the 50ml of solution * We are going to determinate the percent of copper from the mass of copper and the percent zinc by two methods: 1. The titration experiment 2. The precipitation experiment *Now we first got 10 ml of ZnCI2 *To that we added 6 drops of our color indicator (Prenolpthen) *After that we got 50 ml NaOH solution *Than we titrate the ZnCl2 with NaOH *Until we got pink cluster *Now we put the clusters in a paper filter that was dripping the solution living only the clusters *With a tube we connected a vacuum so this way we  were left with only the salt *After this we put the salt in like an oven so that this could dry the salt and this won’t be wet *When we took it out all we had was dry salt and we weight it and started our formulas Results: I calculated the percent % of salt of Zn(OH)2. First I determinate the formulas for both, follow by calculating the atomic mass of Zn. First I had to have the weight of the salt, so I did all the procedures on top. My result for the weight of the salt was .33g and the result of the Zn was .2174. To be able to get percent I calculated by dividing 2.174 witch is the grams of Zn and 2.5 grams multiplying the result by 100 = 86.994% Conclusion and discussion: During Experiment 8 conducted April 16 2014. I noticed the difference in the % for the reaction, when titrating ZnCI2 with NaOH solution. For this experiment we did 2 trials since in the first one we did not get any clusters, but on the second trial we did get some and we got more salt than anyone else.

Bureaucratic Leadership Style Winston Churchill

Bureaucratic leadership style has a long history. It’s been used in politics and in religions organisations around the world. The effectiveness of the style has seen a number of great leaders take advantage of the framework, with business leaders understanding the essential nature of the style. Who are some of the bureaucratic leaders you might want to look up to? Below are four examples of the benefits and the occasional downside of the leadership framework. Winston Churchill While the British Prime Minister, Winston Churchill, showed a number of different leadership qualities, bureaucratic leadership is definitely among the strongest models he used. Churchill had charisma, which he used during the Second World War, but he also relied on a heavily structured system to get things done. Churchill’s key bureaucratic leader traits were his decisive nature and persistency to follow the plan. Churchill was wary of both Stalin’s Soviet Russia and Hitler’s Nazi Germany right from the start. This wasn’t a popular assessment of the time and the British Government didn’t believe the stark images Churchill was painting about the future, but Churchill stuck to his decision-making and view of the two leaders. Eventually, as war began to tear Europe, Churchill was voted in and he created a decisive plan to defeat the enemy, no matter the cost. Furthermore, Churchill also showed plenty of persistency. In his famous speech, Churchill said, â€Å"Whatever the cost may be, we shall fight on theShow MoreRelatedFrom Mahatma Gandhi to Winston Churchill to Martin Luther King2352 Words   |  10 Pagesto Winston Churchill to Martin Luther King, there are as many leadership styles as there are leaders.
