Chemical Engineering Department FIRST YEAR LABORATOY REPORT #1 Name: Shams Alizada Experiment Title: Chemical Kinetics: The Iodine Clock Experiment Date : 13 October 2016 Submission Date: 20 October 2016 Supervisor: Rashid Akhundov   Contents Synopsis 2 Introduction. 3 Safety Precautions

A clock reaction is a form of chemical reaction where multiple reagents are placed together with no apparent change after a time lag until a dramatic colour change appears – called the induction period (King, Preece and Billingham, 1999). This abrupt colour change can be due to the limiting reagent being fully consumed which allows the remaining chemicals to react resulting in a colour change. Specific kinetic and stoichiometric conditions are required for this standard clock behaviour to occur

As my alarm clock startled me from sweet dreams, I grinned realizing game day had come upon us. I leapt out of bed in excitement as I skipped to the bathroom. I filled the bathroom with “Today’s Hits” on Pandora, sprang in the shower, and danced while scrubbing my hair. After showering, I brushed my teeth, gave the mirror a cheesy smile, and headed to my room. I slipped into my Crestwood Girls Basketball long sleeve and a pair of jeans. I combed through my hair and decided to let it air dry. I gulped

Introduction The iodine clock reaction is used as an introduction to experiments on rates / kinetics. The experiment illustrates the effect of concentration of reactants on the rate of reaction. The term “clock” is used to refer to the period of time for changes to occur in solution. In this experiment, two colourless solutions are mixed together which eventually turn dark blue, an indication that the reaction had occurred. The chemicals required for this experiment are starch, potassium iodide,

on this clock. Although this clock seems to be melting like the others in the picture, the fly plays an important part in this painting. Being the painting is named, The Persistence of Memory, the fly leads the onlooker to think these memories might not be as old as the rest. Flies are drawn to items that are rotting but still have some nutritional value; this clock is fresh enough to have more value than the other clocks around it, giving the spectator the thought that maybe while the clock is a memory

How do deaf people use telephones? What about doorbells and alarm clocks?      There are many everyday devises that we hearing people take for granted, among these are telephones, smoke alarms, doorbells, and alarm clocks. When we look at how members of the deaf community use these everyday items we must consider that members within the community have very different communication needs, abilities, and preferences. Hard-of-hearing people for example can use a standard telephone

Complexity in American Education Control Often times, we hear the words complex and complicated used interchangeably. In fact, out of curiosity, I highlighted the two words in Microsoft Word after typing them in the previous sentence and looked at the synonyms provided. Oddly enough, complex is synonymous with words such as multifaceted and intricate. Yet, when I pulled up the synonyms for complicated, complex was the first word listed. What is complexity? How does it differ from complicated issues

INTRODUCTION This paper aims to explain the relationship between marketing and customer value and their relevance when promoting and ensuring customer satisfaction. It will discuss marketing as a business philosophy and its importance in organisations. The concept of customer value will also be examined and its significance to the success of a product. Throughout the paper, the Apple Watch will be drawn on to further explore the concepts and to put them into context. Marketing has been defined

As a leading manufacturer, Sony appeals to both consumers and professionals through their innovative inventions to improve lifestyle and convenience to suit the needs of the future target market within their economic budgets. Wearable technology, in the case of Sony

and thought for a second. Then, something in my kitchen caught my eye. A clock. 38How could I not know that a clock in the house was making the noise! Relief struck me like 39lightning, powerfully and quickly. I skedaddled and grabbed the clock I had originally spotted. After, 40I collected the few other clocks that hung in my house. Once more, I flew out the door to get the 41hammer. Just like before, I smashed each clock to its death. Just like you do to people, I buried the 42clocks right by
