Common People Of The Times
902 wordsESSAY ON THE LATER MIDDLE AGES (1300 1500) The Later Middle Ages is characterized as being a time of overwhelming hardships, catastrophes and struggles. Both natural disasters and man-made ones seemed to strike constantly and relentlessly. What progress was made during this time is seen as less then previously or since; though not entirely non-existent. However, it should be remembered that humans have a habit of remembering the "bad" times and forgetting the "good". Professor Webber also brough...

Initial Rate Of The Reaction
1,017 wordsPLAN Introduction: After having built up knowledge about the kinetics of reactions I decided to do an investigation in this area. I was initially introduced to this particular reaction 1 in EP 6.4 and then in AA 2.1. I was interested in using this reaction as a means of potentially supporting and quantifying some of the theories that I have studied along with also perhaps extending on them. Aim: Using a clock reaction I shall: o Investigate the effect of concentration for each reactant and use t...

Faster The Rate Of Reaction
1,652 wordsExperiment: Investigation into the factors that effect the rate of reaction I am going to investigate how different factors affect the rate of a reaction. Introduction What is a reaction? A reaction is when two particles (reactants) join to form a new product or products. What is rate? Rate is a measure of how fast or how slow something is. Rate is a measurement of the change that happens in a single unit of time, any suitable measurement can be used such as seconds, minutes, hours or even days....

Reaction Times To Mental Rotations Of Images
1,150 wordsAbstract The idea of mental imagery has always been a controversial subject in the field of psychology. Many psychologists have argued that such a concept is impossible to measure because it can not be directly observed. Though they are right about this, it is not impossible to measure how quickly mental rotations of images are processed in our brains. Subjects in this experiment were presented two shapes simultaneously, via computer screen, and asked to make judgement, as quickly as possible, a...

Every Year Ten Million Vaccinations
1,968 wordsIn 1996 a mother took her six-month-old son, Jonah, to the doctor to get his DPT vaccination. Two days later, Jonah came down with an ear infection. Bobbie took him into the doctor and the child was given a prescription of amoxicillin. The ear infection soon healed and all went well for about two months when the infection returned. Bobbie again took Jonah to the physician where he, this time, gave the boy a stronger form of amoxicillin. Again the infection soon diminished. About four months late...

Temperature By 10 The Rate Of Reaction
1,777 wordsTITTLE; Effect of temperature on the rate of reaction Aim I plan to investigate the effect of temperature of acid, in the reaction between concentrated hydrochloric acid and magnesium ribbon. The rate of chemical reaction is a measure of how fast the reaction takes place. It is important to know that a rapid reaction is completed in a short period of time. Some reactions are very fast, e.g. a reaction after a fire work is set. In this investigation I will test different temperatures of acid reac...

Rate Equation For The Reaction Between Sodium
504 wordsChemistry Coursework- Planning Introduction In this piece of coursework I will attempt to design an experiment that will lead to a graphical procedure to determine the rate equation for the reaction between sodium thiosulphate and hydrochloric acid Scientific knowledge Before any chemical reaction occurs two or more molecules of the reactants must successfully collide together in the right orientation (the correct angle), the more collisions the faster the reaction rate. Concentration is just on...

Temperature Of The Starch And Amylase
1,436 wordsAim The aim of my experiment is to investigate the effect of temperature on breaking down starch due to amylase. Background Info Amylase is an enzyme. It is found in the human body, in the pancreas and the small intestine. Amylase breaks down starch into maltose and other simple sugars. This takes place in the salivary glands and starts the process of digestion and also occurs in the small intestine. Enzymes are: very potent biological catalysts, proteins, made by living cells, sensitive to chan...

Alliances Between The Remaining Guests
972 wordsBy chapter 13 of And Then There Were None, by Agatha Christie, half of the ten guests that ventured out to Indian Island are killed. These incidents cause the remaining guests to react in bizarre ways. These reactions are common to most people that are placed in this situation. They protect themselves and react differently around each other. There are also accusations that are made about who may have done the killing of the first five guests, and there are alliances that are made to help find ou...
