determine the reaction time of the test participant and using the subtractive method identify the selection time and identification time of the participant. The experiments had one participant who participated in a total of 6 experiments; two experiments required a simple reaction with a single stimulus and 4 experiments that required a more complicated reaction. Keywords Subtractive method – the procedure of estimating the time it takes to perform various cognitive operations. Simple reaction – this

SN1 Reactions For SN1 reactions it’s important to have a good leaving group because this reaction occurs in two steps. Because alcohol is such a poor leaving group it needs to be helped by silver nitrate to help promote the ionization of the alkyl halide. This helps form the products of the SN1 reaction. 2-chlorobutane This reaction didn’t occur because the carbocation isn’t stable enough for an SN1 reaction. 2-bromobutane This reaction occurred in 32 seconds. This reaction occurred quickly

A federal law was passed barring entry to all convicts and prostitutes. Before then‚ immigration was scarcely controlled. Over centuries different laws were passed in attempt to get the situation under control. Once the Immigration Law passed‚ legal immigration

on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

Wilson’s causes the body to retain copper that has been taken in through an individual’s diet‚ rather than the liver turning it into to bile to be disposed of. The liver becomes more and more damaged as the copper accumulates‚ and when it has no other place to be stored within the liver‚ it gets released into the bloodstream‚ carrying the copper throughout the body‚ onto other organs. This is how the accumulation of copper not only affects the liver‚ but manages to affect the nervous system‚ eyes

There are eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species

SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane.
