RELATIONSHIPS THAT CONCENTRATION AND TEMPERATURE HAVE ON THE RATE OF REACTION Aim To study the effect that temperature and concentration of iodide ion solution have on the rate of iodide ion I⁻ oxidation by peroxodisulphate ion S₂O₈⁻‚ creating an iodine clock reaction. Introduction I decided to choose as the topic for my investigation the rate of reaction for its vital importance in the human body. Indeed I am really interested in Biology and especially physiology and I would like to study medicine. The

True to it’s common characteristics‚ Chimabue’s "Enthroned Madonna and Child" stays loyal to the style of Italo-Byzantine art. Giotto’s "Ognissanti Madonna" however‚ in some key areas‚ strays away from the conventional techniques of the style. Chimabue’s approach to composition in the artwork "Enthroned Madonna and Child" was extremely confirmative to the time period. He made use of the medieval heiracy of scale‚ making Mary and baby Jesus much larger than other figures‚ therefore making them

The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

with his major conflict being good vs. evil. In conclusion Anthony Burgess shows the significance of different flaws while simultaneously showing how when they come together a dystopian society is created. You thesis unclear. What is the point you are trying to make? One of Anthony Burgess’s‚ A Clockwork Orange‚ most important believes is that the freedom to choose is the big human attribute. In other words the presence of moral choice ultimately distinguishes human beings from machines and animals

difference between the end of the Medieval Era and beginning of the Renaissance Era showed amazing changes in the form of art. The painting “Madonna the Goldfinch” by Raphael Sanzio was created in c. 1505-1506. This was the very beginning of the Renaissance Era‚ and the painting strived for perfection unlike any of the paintings created before it. Madonna the Goldfinch portrays a sense intrigued curiosity‚ but to those who analyze it will find a guiding informative response with a deep understanding

a finite speed was a violation of Aristotelian Mechanics (later replaced by Newtonian mechanics) -There were however some notable dissenters. Aristotle condemned the ideas of Empedocles of Acragas who spoke of light as traveling‚ but the movement being unobservable to humans. -Around 1000 AD Islamic Scientists Avicenna and Alhazen separately stated that light must have a finite value. Alhazen argued light has a finite speed that differs depending on the medium it travels through. Historical Measurements

CHEMICAL KINETICS: IODINE-CLOCK REACTION DATE SUBMITTED: 14 DECEMBER 2012 DATE PERFORMED: 7 DECEMBER 2012 ABSTRACT Chemical kinetics involving reaction rates and mechanisms is an essential part of our daily life in the modern world. It helps us understand whether particular reactions are favorable and how to save time or prolong time during each reaction. Experiment demonstrated the how concentration‚ temperature and presence of a catalyst can change the rate of a reaction. 5 runs of dilution

Astronomical Clock “Tick tock‚ tick tock” is a common sound from today’s clocks. When traveling in Prague in the Czech Republic‚ the normal everyday clock is not to be found in front of “the Old Town Hall.” Instead‚ the Prague Astronomical Clock overshadows all other clocks with its magnificent craftsmanship. The delicate clock is filled with different mechanics that make it work‚ along with legends and stories to come along with it‚ and the many different times it tells. Normal clock mechanics

The Madonna of Chancellor Rolin is an oil painting by Netherlandish master Jan van Eyck. The revolutionary Flemish master founded the Flemish School of Painting and was the court painter for Duke Phillip the Good of Burgundy. Jan Van Eyck primarily focused on oil paintings during his career. He was so good at manipulating oil glazes that people would mistakenly give credit to Jan van Eyck as the founder of oil painting. The painting that gave recognition to Jan van Eyck’s career dated back to 1435
