EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Does peaceful resistance to laws positively or negatively impact a free society? Peaceful resistance to laws does not negatively impact a free society. If one wishes to peacefully protest then it should be allowed. However‚ the resistors should realize that there could be negative effects and consequences because of their actions. Especially‚ if laws are broken or the protest becomes violent. It is important in society today for teens and young adults to realize that negative

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

predicted. To improve my experiment to make it even more reliable I could use a more accurate ammeter and a larger range of results as well as more checks. The ammeter I use could be more than two decimal places‚ and I could get a lot of results and put them on one graph to make my results are reliable and I have a good accurate graph. Analysis When the bulbs received more current the molecules in the bulb vibrated fast and the bulb became warmer as the resistance increased. As the voltage

Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6
