carbocation‚ and (3) attacking of the nucleophile to the carbocation. The experiment was only able to yield 0.504 grams or 5.21% of the theoretical yield of 9.679 grams‚ which is considered as extremely low percent yield. This result could have resulted from various experiment and experimenter errors and other uncontrollable environmental factors. Introduction An alkyl halide or haloalkane is composed of hydrocarbons with a halogen attached to a sp3-hybridized carbon. It resembles an alkane with

percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid catalyzed aspirin‚ we saw an average of 55.0% percent yield and an average 42.2% percent error. The Ka value for sulphuric acid is 1.0 x 10³ while the Ka value for phosphoric acid is 7.1 x 10⁻³. Knowing that the Ka value denotes the acidity of

benzoate form benzoic acid and methanol by using the Fischer esterification method. The Fischer exterification technique is utilized in the academic and industrial settings due to the simplified synthesis and safety parameters of the overall reaction. Both benzoic acid and methanol are relatively cheap to obtain from a commercial source as well as being easy to store with a relatively long shelf life. The Fischer esterification method is a fundamental and important synthesis process in training our

Acid Rains There are three gases which could cause acid rain‚ which are Sulphur Dioxide (sulphuric acid)‚ NOx (oxides of nitrogen which produce nitric acid) and also perhaps Carbon Dioxide (weak carbonic acid)‚ produces these acids because these gases dissolve in rain water/ precipitation and this forms a weak version of the acid‚ as the gases dissolve it lowers the pH of the rainwater. I think that there has been a increase in the production of acid rain‚ due to the fact that the country as a

OIL PAINTINGS One of the images that I’m most fond of is the “Madonna and Child with the Chancellor Rolin” by Jan and Eck. This piece is one my favorites because it uses oil. When using oil the images of the paintings seem to realistically speak to me. This particular painting enables both fusion of tones and crisp effects and is unsurpassed for textural variation. The standard consistency of oil paint is a smooth‚ buttery paste. In this scene it depicts the Virgin crowned by a hovering Angel while

Lactic Acid Bacteria Amanda Perry Many persons are oblivious to the fact that when they consume certain delicious food products like yogurt‚ buttermilk or cheese‚ they are actually eating live bacterial biomass which has acidified the milk content and contains a mixture of bacterial slime layers. Perhaps it is a blessing that most people are unaware because when most hear the word ‘bacteria‚’ their first thought is of a microscopic unicellular organism that causes various types of diseases especially

Two regular people with an extraordinary love. No matter how bad it gets they will prevail. This OIL ON CANVAS painting tells an exceptional story about love‚ conflict‚ compassion‚ resolution‚ and friends. It shows the couple dancing in a rainstorm‚ one person holding an umbrella over the couple‚ with the CANOPY protecting them from rain. Another person running for cover from the rain. It seems as if the dancing couple is completely ignorant of the rain. The artist isn’t talking about a light
