Reaction Rate Coursework Aim To see how the concentration of a reactant affects the rate of reaction‚ in this case sodium thiosulphate and acid. Scientific Background For a reaction to occur‚ the particles of the reactants must be colliding with each other with enough energy‚ the amount of energy needed for the reaction is called activation energy. Activation energy is altered by temperature‚ concentration‚ surface area of and the pressure on the reactants. Stirring the reactants also increases

During WWII & the reign of Hitler was the Auschwitz Concentration Camp‚ a labor camp‚ which could be considered to be one of the worst places for a person of the Jewish faith place to be at that time in history. Handed down through history‚ it is considered to be one of the brutalist places on earth that a person could be. As James Deem described it‚ “Prisoners receiving punishment were often placed in cramped basement cells and deprived of food” (9). To be put into simple terms‚ it was torture.

In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator

The Chelmno concentration camp was used as an extermination camp during the Holocaust. It was known by the Germans as Kulmhof concentration camp. This camp operated in two periods during the war; from December 8th‚ 1941 to March 1943‚ and from June 1944 to January 18th‚ 1945. The first period was open during the most deadly phase of the Holocaust known as Aktion Reinhard and the second period was open during the Soviet counteroffensive. This camp was specifically built to exterminate Polish Jews

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is

Purpose: The purpose of the ‘Rates of Reactions’ lab is to learn how to plan an investigative lab without outside help and to learn about the ‘Rates of Reactions’. This lab will require students to take responsibility for their own learning and use their prior knowledge to aid in the completion of this lab. In the lab prepared below‚ students will be learning about Rates of Reaction with varying concentrations of Alka-Seltzer with water. Hypothesis: I believe that the more water added to the canister

Once Upon a Time by Gabriel OkaraOnce upon a time‚ son‚they used to laugh with their heartsand laugh with their eyes:but now they only laugh with their teeth‚while their ice-block-cold eyessearch behind my shadow.There was a time indeedthey used to shake hands with their hearts:but that’s gone‚ son.Now they shake hands without heartswhile their left hands searchmy empty pockets.‘Feel at home!’ ‘Come again’:they say‚ and when I comeagain and feelat home‚ once‚ twice‚there will be no thrice-for then
