An Accident from My Memory Essay

The cold numb feeling was freezing every part of me as I sat quietly inside the car that was twirling in the middle of the highway. Sitting there and patiently waiting for the airbag to explode and cover me as if it was my moms arms took some fear out of me but my body still shivered as if there would be no tomorrow. Even though its been almost four years, I can still recall that day as clear as crystal, yet most of me wished it would just turn into thin air and disappear. As I sit still today, I think of what would have happened to me if I had lost a loved one in that incident. That night made me realize about two important concepts in life. First, to respect what we have and make the best of our time because we never know when life can take it all away and second, to respect nature because when nature prevails itself, it can either kill us or save us. My hands were shivering as I went to go lock my front door, as I was turning the key I felt a large breeze of air pushing me back as if god himself did not want me to leave. As I moved towards the car I felt as if something was weird, it seemed as if I had a dà ©jà   vu but I assumed that it was because of the fact that I did not eat anything the entire day. Slowly I opened the door to the car and sat in the front seat, as I sat down I heard a man on the radio saying that today would be the best day we are going to experience the entire winter, hearing that made everyone glad as we left towards Ottawa. With time we realized that the experience we were going to have is not going to be the best but the worst. As time passed we headed towards Ottawa, leaving the house behind and not knowing what to expect next. While blasting the music in the car I thought about how great this weekend would be and how much fun were going to have with the beautiful weather. At first everything seemed to be perfect as my dad was cruising along the smooth pavement at 110 km/hr but then things begun to change when the car started making a very soft yet annoying sound, hearing the sound my dad pulled over. Being on the side of the highway and staring out the window amazed me because I saw hundreds of cars going by every second. Watching the cars fly by fascinated me but at the same time they also terrorized me, while I sat still I thought about how one of the car might crash into our and destroy us all, thinking that I fell asleep. As I was sleeping I felt someone tapping my shoulder. The feeling of that tapping on the shoulder made me get up and as I looked over I saw my dad standing still saying wake up Ankit, wake up. Hearing the sound I woke up and as I looked up at the sky I saw total darkness and I noticed that I had been sleeping for three hours. As I walked towards Pizza Hut to eat I felt small water drops falling on my head and hands, at first I thought it was a small drizzle of snow that would stop in a few minutes but later I figured that the snow would get worse. As we finished eating we saw large amounts of snow falling on the road and making the roads more slippery. As I walked back to the car I looked into my moms eyes and noticed that there had been something frightening she saw, perhaps it was the large amounts of snow, I thought. Disregarding the snow we kept going and driving at high speeds towards Ottawa. At first everything seemed so beautiful because the pellets of snow slowly fell upon one another but with time they started getting bigger and bigger just like the terror in my moms eyes. Giving my mom sympathy and telling her we are going to make it to Ottawa safely helped her to calm down but there was still some terror that I could see. Talking to my mom surely made her feel better but at the same time it distracted my dad. When my dad had gotten distracted he lost his controls on the car which caused it to go out of control and twirl around in the middle of the highway. Luckily, when the car was twirling in the middle of the highway there was not a lot of traffic so the ones behind the car had stopped. However, other cars on the side of the highway kept going; as I stood in the front seat tightly gripping my belt I thought to myself that I would never see a tomorrow. As the car slid I looked at my family because they were the last people I would see before the airbag would explode and take me far away from this planet. My nerves were popping out of my skin as I held the grip tightly. Looking out the front window and watching cars drive by scared me even more because I knew if any one of those cars were to crash into ours then our chances of survival would be very low. As I sat still in the car I thought about how I  would die, would it be in the hospital or would it be a simple death. At that moment my thoughts were not very positive and all that went through my mind was one question. Would I live or die? But believing in myself I decided to face my fear and bring back my senses just like my dad. Once my dad had gotten his senses back he had shifted the car into lower gear and pressed on the break frequently which eventually made the car stop. My dads consciousness gave me a second life and made me learn some important concepts that I would have never understood if I hadnt been a part of that incident. As time passed my wounds healed but the incident left me with a scar that may never be removed. Now that I look at my car I can recall those exact moments that made me more fearless. I have now learned that people should never challenge nature because nature can easily make a dramatic change and kill us all.

How the Concentration Affects the Rate of the Reaction

Title Page Number Diagram of Apparatus Introduction Risk Assessment ` Table of Results Line of Best Fit Graph Error Bars Graph Gradients Graph Analysis †¢ Error Bars Analysis Evaluation †¢ Improvement Assessment †¢ Improved Experiment. †¢ Reliability References Introduction: For this data analysis project, I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction.I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1, I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the product of the reaction between sodium thisoulphate and hydrochloric acid (HCL) is precipitates of sulphur which tend to turn the solution cloudy.As a result, the cross beneath the conical fla sk (see figure 1) would disappear/ become difficult to be seen when the reaction has taken place. Therefore, the idea is that 50 cm? of sodium thisoulphate are made to react with 5 cm? of hydrochloric acid that is of different concentration each time. The concentrations of hydrochloric acid used varied from 0. 1 to 5 moles. Afterwards, the cross is observed through the top of the conical flask until it because invisible. The time of which this happens is then recorded and monitored using a stopwatch.The symbol equation of this reaction is as follows: The above symbol equation shows the reaction: Sodium thisoulphate reacts with hydrochloric acid to form sodium chloride, water, precipitate of sulphur as well as sulphur dioxide. The results that I recorded from this experiment were poor. This is because they were not entirely accurate and did not make sense. As a result, my teacher gave me a different set of results that were recorded at different temperatures to analyse and help me wr ite up.The table of results (table 2), shows the results obtained at 3 different trials of the same experiment. The reason behind repeating the experiment 3 times is to ensure that the result’s reliability is of a satisfactory level. After the experiment was conducted, I looked back at the equipment I used as well as the steps I carried out during the process. I did so to recognize the risks associated with carrying out such experiments. To prevent or minimize such risks in future experiments, I conducted a risk assessment that is shown on the following page: Risk Assessment Risk |Damage |Prevention Method | |Hydrochloric Acid (HCL) |Hydrochloric acid is corrosive. |Eye protection must be worn at all times during | | |Therefore it can damage skin. |the experiment. | | |It can also damage eyes. |Ensure it does not come into contact with skin | | | |and if it does rinse thoroughly. |Conical Flask (glass) |Can roll down the bench |Make sure apparatus made of glass are not | | |B roken glass can cut/damage skin. |chipped. | | | |Wear gloves if possible | | | |Be careful when handling glass. | | | | | | | | |Sodium Thisoulphate |Inhalation may cause irritation and coughing. |Avoid contact with eyes and skin. | | |Skin and eye contact might cause irritation and |Do not inhale on purpose. | |damage | | |Paper |1.

Risk Assessment (Table 2) Analysis: Outliers: Table 2 summarises the results of this experiment. As you can see, a couple of outliers have occurred during the experiment. I decided that a difference of more than 30 seconds between a result and the others obtained from repeating the same experiment indicates that this result is an outlier. Therefore the two outliers are ringed on table 2, so that they are made clear. For instance, the results recorded for the third experiment using 0. 1 moles c oncentrated hydrochloric acid is 583 seconds.This is clearly an outlier due to the fact that the other results are 683 and 626 seconds, making the result of 583 seconds clearly distant and therefore is classed as an anomaly. Another outlier that has occurred is the result for the 3rd trial using 4. 0 moles hydrochloric acid. Here the outlier is 132 seconds, while the other trials show results that vary from 160 to 165 seconds. Graph Analysis: The first graph (figure 2) states the averages of the recordings. I have used a line of best fit on this graph to identify the trends between the results.Firstly, the graph shows overall that the experiment has gone as expected. This is because it looks very similar to the graph in the chemistry text book as well as ones found on the internet. The general trend that is shown by this experiment (as seen on figure 2) is that as the concentration of the hydrochloric acid increase, the rate of the reaction also increases, as the reaction takes less time to take place. Therefore, the experiment shows that the concentration of the acid is directly proportional to the rate of the reaction. From 0. to 0. 5 Moles: As you can see by figure 2, when 0. 1 moles of hydrochloric acid were used, the reaction was at its slowest, taking 656 seconds to take place. From 0. 1 to 0. 5 moles, the rate of the reaction increased significantly with the reaction only taking around half the time: 379 seconds to take place. At the start, the line of best fit has a gradient of 0. 000152 moles per second (m/s). I worked this out using the equation x/y = 0. 1/656 = 0. 000152 m/s. At 0. 5 moles, the gradient of the graph increases rapidly to 0. 00132 m/s.This calculation reinforces that the reaction is at its slowest at the beginning with the sulphur precipitate taking the least amount of time to cloud the solution and causing the cross to become invisibile. This is because a low concentration of hydrochloric acid means that not as much molecules are ava ilable to collide, making molecular collision much less likely (). From 0. 5 to 1 Moles: From 0. 5 to 1 moles, the time taken for the reaction to take place decreases further as the rate of the reaction increases. Therefore the precipitate of sulphur is taking less time to form ().The gradient of the graph also increases as a result to 0. 00357 m/s. I have worked this out using the same equation as above: x/y= 1/280. This indicates that the rate of the reaction keeps on increasing as the concentration of the hydrochloric acid increases. From 1 to 2 Moles: By increasing the concentration of the acid from 1 to 2 moles, the rate of the reaction kept on increasing by taking less time for the reaction to occur. This is again shown by the line of best fit on figure 2, which at this point in the graph has a gradient of 0. 0913 m/s (x/y = 2/219), which is nearly triple the gradient stated previously. The rate of the reaction is a measure of how quickly this reaction is taking place. As you can see by the negative correlation between the time and the molarity of the acid shown on figure 2, the rate of the reaction keeps on increasing as the concentration of the hydrochloric acid is increasing. This result is supported by the collision theory. This theory indicates that for a reaction to occur, the particles or molecules must collide with each other to form a reaction.Infact, they need to collide hard enough for the reaction to become a successful one as well, since only a certain fraction of the total collisions actually result in a chemical change (). When those successful collisions occur, they have enough activation energy to break existing bonds and form new bonds, resulting in a chemical reaction and a new product being formed (). Increasing the concentration of a solution means increasing the amount of molecules that are available in that solution.Therefore, increasing the concentration of the hydrochloric acid from 1 to 2 moles is increasing the amount of molecu les in the acid that would be available to collide and cause a reaction. Therefore, this means that there would be more particles per dm?. The fact that more particles are available explains why the rate of the reaction becomes faster. This is because the more particles there are, the more successful molecular collision would be happening, which increases the rate of which the reaction occurs. This aspect of the collision theory is illustrated by the diagram below:The Collision Theory (figure 5) (). As you can see by the diagram above, the amount of collisions happening per second is a major factor that determines how quickly or slowly the rate of the reaction goes. Therefore a high concentration increases the chances of collisions and consequently results in an increase in the rate of the reaction. From 2 to 4 Moles: When increasing the concentration of the hydrochloric acid again from 2 to 4 moles, the trend still obeys the collision theory as far as the increase in the rate of th e reaction is concerned.This is reinforced by the dramatic gradient increase to 0. 025 m/s (x/y = 4/163), which is shown by figure 2 as well as 4. According to the collision theory, it is expected that when the concentration of the hydrochloric acid doubles, the rate of the reaction will tend to double as a result too. On the other hand this does not seem to be the case in this experiment, since the time take for the reaction to take place when 2 moles hydrochloric acid was used is 219 seconds, while it is 163 seconds when 4 moles hydrochloric acid is used.This indicates that the reaction happening at this experiment was not a perfect one. This could be as a result of human error or other factors affecting the rate of the reaction, which will be discussed later. From 4 to 5 Moles: Finally, by increasing the concentration of the hydrochloric acid used from 4 to 5 moles, the rate of the reaction was increased to become at its highest during this experiment, with the steepest gradient of 0. 035 m/s (x/y = 5/141).This implies that the amount of successful molecular collisions here are the highest with the sulphur precipitate clouding the solution in the quickest rate of time (141 seconds). Thus, the cross disappeared at the quickest rate as well. Error Bars Analysis: The second graph (figure 3) is a graph of error bars. Error bars show the range of results. I have drawn this graph since it is a visual account of the experiment’s reliability and so, it would help me decide whether the experiment was accurate enough or not. As you can see, the size of the error ars on figure 3 varies from small to large ones. I have decided that a bar range of 5 small squares on the graph is a reasonable maximum to detect the experiments accuracy. So, any range bars that vary above 5 small squares show inaccurate set of results. The error bars drawn on figure 3 show that the results obtained from 0. 1 to 0. 5 moles are rather inaccurate. This is because the error bars illustr ated for those set of results are relatively big, showing a difference of from 6 to 10 small squares. This implies that those results with big error bars are quite poor and lack accuracy.However, the rest of the experiments show relatively small error bars. In addition, the error bars seem to be getting smaller and smaller with a bar range that varies below 5 or 4 small squares. This proves that the results keep getting more and more accurate towards the end of the experiment which makes. Overall I believe that the results of this experiment are 71% accurate. This is because 5 out of 7 of the error bars had a small range, leaving 2 out of 7 of the error bars with rather big range bars. Evaluation:

Land Grabbing in Africa Essay Example | Topics and Well Written Essays - 1250 words

Land Grabbing in Africa - Essay Example Land grabbing in East Africa causes imbalance between the efforts to build sustainable systems that comprehensively try to resolve land-related tensions and interests, as well as pursuits to economic development (Palmer, 2012). Due to this, Heads of States of Africa and Governments have adopted Framework and Guidelines on Land Policy in East Africa. This is to inspire and prompt countries to develop land policies that take into account their particular needs. The presence of continental framework and guidelines and normative instruments like the 11 principles laid out on the Right to Food by the UN Special Rapporteur ensure economic development without weakening the development of any population group. The World Bank plays a greater role in the land grabbing in East Africa. It refers to the land grabbing as agro-investment and makes room for it by creating seven voluntary principles to make the practice of agro-investment responsible. All the seven principles are supposed to safeguard the East Africa’s land from being grabbed. However, this is just a mirage, for these principles are not adhered to, they are just there as beautifying statements. This, therefore, makes the transactions regarding land negative for both the buyer of the land and the seller. Wealthy States are the main causes of the increase in rural poverty that drives many people off the land that they have for generations farmed (Pearce, 2012). For example, there are major environmental and agricultural damage along River Niger caused by the International Land Coalition. This is a global network of civil society and farmers’ organization. Forestry and small scale farming that protects food, unique wildlife and heritage is slowly being converted to wastelands that only profit agribusinesses. Multinational companies in a greater number that vastly exceed the usage by the local communities are using natural resources. As a result, the land’s

Local ownership a dilemma in peace building Essay

Local ownership a dilemma in peace building - Essay Example Local ownership as far as the peace building is concerned refers to the degree of involvement of the domestic actors in formulation and implementation of a political process. In addition to local ownership issues, the Afghanistan state has remained crippled due to rampant corruption, emboldened insurgency and political disunity. The citizens have already grown tired of having international bodies present and demand the return of ownership of policies to their state. However, there is great tension that chaos might reemerge once the international communities hand over the local ownership to the Afghanistan citizens. The paper gives a analyses the dilemma that faces the local ownership especially in the Afghanistan state. The citizens of Afghanistan began opposing the idea of local ownership after making several findings about the local ownership process, according to the Afghanistan case study. The case study shows that local ownership process in Afghanistan is subject to both practical and structural problems. Practical problems identified by the case study include mutual mistrust, dependence on external forces and lack of capacity among others. Structural problems identified include moral superiority and problem of the independence in the state. Primarily, the findings show that the local ownership process in Afghanistan was not feasible because there was mutual mistrust and suspicions between the various actors involved in the peace-making process. This deepened the tension amongst the citizens. They no longer trusted each other and thus making it difficult to have a common political leadership that all the citizens and the actors, both local and international would agree to. Despite the local and international actors having a common goal of intervention, differences arose over what a sound end state capable of sustainable peace appears like and how to attain it. The various actors could not agree due to mistrust. Another factor that made the local

Progressive Period Research Paper Example | Topics and Well Written Essays - 1000 words

Progressive Period - Research Paper Example The researcher states that during the progressive period several people stand steadily to find solutions of the problems, that were faced by America and these people were called as Progressive people. The progressive people worked to create awareness among the general public regarding different problems like alcohol abuse, child labour, food purity and government corruption etc. As a result of evolving public awareness then government had to pass several laws and acts to solve the problems of the people. The progressive movement was mainly aimed at eliminating corruption within the city government with the help of prohibition that worked for the destruction of political power of the local bosses that used to be based in saloons. The activists also worked for the promotion of women’s suffrage and eventually purer female vote was brought into the arena. During the progressive era efforts were also made to achieve high productivity and efficiency in different sectors by fostering modernization process. There were different scientific, economic, medical and engineering solutions invented during this era to support the performance of different sectors. The progressive movement was initiated at local level during the early stages, however soon it was expanded and spread to the national and state levels as well. It was also discussed how the progressive people had great support from the middle class and many lawyers, teachers; physicians became the supporters of the progressive movement. ... As a part of application of the scientific methods it was realized that the old fashioned ways of running the economics, industries and government are highly inefficient and waste the time and resources. To avoid this wastage the progressive movement worked for adaptation of different policies like banking laws that resulted in the creation of Federal Reserve System in 1914 (Leuchtenburg, p504). The progressive period activities proved them dedicatedly committed to bring reforms and changes within the country. They expect that the changes they sought could significantly improve the American society. Some of the major changes enacted during the progressive era include the income tax imposition with the Sixteenth Amendment, direct election of Senators through the Seventeenth Amendment Prohibition ad the Nineteenth Amendment to the U.S constitution that was meant to enact women’s suffrage. The journalist played an important role during the progressive movement as they worked to m ake people aware and informed about the corruptions being committed at the government level. These journalists were called with the names of Muckrakers who worked for exposing the waste, corruption and scandals of the authorities and government officials. They use the medium of highly influential and popular national magazines like McClure Magazine, Brand Whitlock and George Creel and published the stories and facts to uncover the wrong deeds and corruption of the government at local and state level. There were several frauds and corruption cases uncovered in these magazines. The progressive movement was also led by the motive of modernization implementation within the society. The
