In this experiment there is two parts to fulfill. One included the synthesis of tert-butyl chloride and the other consists of qualitative chemical tests for reactivity. During the synthesis portion one will perform a series of procedures to add and draw off different chemicals in a seperatory funnel to attain tert-butyl chloride. “During the qualitative chemical tests one will use silver nitrate and sodium iodide to perform SN1 and SN2 reactions with tert-butyl chloride and 1-chlorobutane” (3). There are two types of reaction mechanisms and that is substitution and elimination. In this experiment it is only focused on substitution reactions. “In a substitution reaction, an electron-rich species donates a pair of electrons to an electron poor species which forms a new product and a new base” (2). There are multiple types off substitution reactions and they are …show more content…
(0.053 mol Tert-Butyl Alcohol) x (1 mol Tert-Butyl Chloride)/ (1 mol Tert-Butyl Alcohol)= 0.053 mol Tert-Butyl Chloride. (0.053 mol Tert-Butyl Chloride) x (92.57g Tert-Butyl Chloride)/ (1 mol Tert-Butyl Chloride) = 4.9 g Tert-Butyl Chloride Discussion The reaction observed in test tube 1 went from a clear solution to light yellow after putting it in the hot water bath for about one minute. The reaction in test tube 2 showed that once all of the substances were placed in the tube it immediately turned a cloudy, milky color. In test tube 3 the reaction observed showed that it immediately went from cloudy to clear after a few seconds. In test tube 4 after about a minute the mixtures became soft white color. My expectations were that all of them would turn cloudy and stay cloudy and that the test tube solutions would not need to be heated. This was not the case for some of the test
In the second experiment with the green color, I can safely conclude that the color green in this case is very soluble and we would need longer filter paper, perhaps more time to safely separate the different colors that make up the color green.
The lab Water to Grape Juice to Milk went through many chemical changes. For each change a chemical reaction took place. There were five changes that happened all together. Every change was produced by mixing different substances together to produce the outcome. The first change was water to grape juice. This was the reaction between distilled water, phenolphthalein solution, and sodium hydroxide. The reaction was the water with the solution turning purple. Sodium hydroxide and phenolphthalein must have been responsible for the change because when the two things were mixed it caused the color to change. Next was the grape juice to lemonade. This was taking the grape juice and mixing it with sulfuric acid. Once again the reaction was the color
Since this test has been devised, the number one question everybody is asking is, “ isn’t it unfair to base a student’s entire future on one test, when he or she simply could have had a bad day when taking the test”? The president Kirk T. Schroder of the Virginia Board of Education, answer this question by saying, “First of all, these tests are untimed, so no student is under arbitrary time pressure in taking the test.

We were surprised when the exact same reaction happened as what happened with Experiment 1, minus the color
Objective: The objective of the experiment is to determine what factors cause a change in speed of a reaction. It is also to decide if the change is correlated with the balanced equation of the reaction and, therefore, predictable. To obtain a reaction, permanganate, MnO_4^(1-), must be reduced by oxalic acid, C_2 O_4 H_2. The balanced equation for the reaction is:
There are many people who simply do not perform well on tests.
Now everything has been done to these tests in attempt to make them more tolerable; they’ve been taken, skipped, enforced, cheated on, changed, taught, even puked on enough that there is now a procedure in almost every test administrator’s instruction manual on what to do if a student were to puke on his or her
Some students simply do not test well, others try their hardest and still cannot reach the impracticable standards set for them. The individuals who create these tests do not understand the pressures of being a student, or the struggle to answer thirty-five questions in a compressed time period. One test cannot accurately measure the intelligence of a student.

Redox reactions involve a transfer or altered sharing of electrons from one reacting species to another. If the oxidation number of an element in a reacting species changes, then that element is said to have undergone either oxidation or a reduction.
In order for the test to be fair I am going to have to make sure that
