Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution

Apple’s Mobile Future: Corporate and Business Strategy June 16th‚ 2010 For my final undergraduate business paper‚ I wrote an analysis of Apple as it transforms into a mobile company. I am posting it here in its entirety (except for financial exhibits) below. Especially since they released the iPhone in 2007‚ Apple has been spectacularly successful. In 2009‚ sales totaled more than $36 billion‚ compared to just $5.3 billion in 2001‚ and their market capitalization is nearing Microsoft’s. This

Slowing the Biological Clock Team B BSHS 371 July 23‚ 2012 Rafael Gomez Slowing the Biological Clock The biological clock is an organism’s rhythm that controls the cycle of behaviors that occur on a daily basis. Slowing the biological clock is in reference to the cells that are constantly changing in an individual’s body. A person should take care of his or her body at a young age because the effects of the care will have outcomes as the person ages. There are several contributing

W.H. Auden poem “Stop All The Clocks”‚ published in 1938‚ describes the death of a loved one and the enormous funeral which followed. The poem consists of four stanza‚ each containing four lines. Auden’s poem‚ explores the ideas of grief‚ through the first person pronoun “I”‚ in order to engage the reader into his personal tragedy. It’s almost as if each stanza expresses a new emotion‚ with the first stanza expressing grief‚ the second stanza expressing public notification‚ the third stanza expressing

MONROE CLOCK COMPANY * Issue: Jim Monroe‚ president of Monroe Clock Company‚ decided to sell a new household timing device. And this complete product would have to be sold through wholesalers and manufacturers’ representatives‚ which were new to Monroe Clock‚ so the price will be an important factor. Jim’s controller‚ Tom‚ had provided figures showing a full cost of $11.60 and factory price of $14.70‚ and Frank Tyler‚ his sales manager‚ had worked out a cost of $6.30 excluding fixed overhead

most effective‚ this aim will be carried out as an iodine clock reaction. The goal of this aim is to find out what catalyst is best to make this reaction occur at the fastest rate. 3. Determine the effects of the presence of ethanol on the rate equation. It is known that ethanol effects hydrogen peroxide and therefore it has an effect on the rate equation. This aim will find out the effect of ethanol by carrying out the iodine clock reaction with and without ethanol present and the results

The Monastery and The Clock - Rhetorical Essay Time‚ is the indefinite continued progress of existence and events in past‚ present‚ and future regarded as a whole. It can be argued that the steam engine is the most important machine developed in human history. Then again it can be argued that Megan Fox is the most amazing actress of all time. It’s the one who provides the most ethos that will win any argument. One can trace the roots of the Industrial Revolution all the way back to the Middle

Rabi‚ a physics professor at Columbia University‚ suggests a clock could be made from a technique he developed in the 1930’s called atomic beam magnetic resonance. 1949 Using Rabi’s technique‚ NIST (then the National Bureau of Standards) announces the world’s first atomic clock using the ammonia molecule as the source of vibrations. 1952 NIST announces the first atomic clock using cesium atoms as the vibration source. This clock is named NBS-1. 1954 NBS-1 is moved to NIST’s new laboratories

An investigation on the activation energy for the iodine clock reaction Introduction: The iodine clock reaction is a presentation of chemical kinetics‚ which are the elements that affect the rate of chemical reactions. When the two colorless solutions are incorporated together‚ no reaction can be spotted. But after a short period of time‚ the solution turns into a dark blue solution. The term rate of reaction is stated as the decrease in the concentration of one of the reactions or the increase
