Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

Sarah Oliver Presentation Heidegger April 19‚ 2012 In Lecture I of Part II‚ Heidegger points out that asking the question of “What is called thinking” can be incredibly diverse and complicated because there is not just one explanation for the question‚ although at a glance it seems pretty simple to explain. He stresses four ways in which the question can be posed. The first way asks what is designated by the word “thinking‚” the second asks what logic has to do with thought‚ the third asks

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

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

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

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

Symbol: Something that stands for or represents something else beyond it. The term symbolism refers to the use of symbols‚ or to a set of related symbols. Example: “Why‚ Petruchio is coming‚ in a new hat and an old jerkin; a pair of old breeches thrice turned; a pair of boots that have been candle cases‚ one buckled‚ another laced; an old rusty sword ta’en out of the town armory‚ with a broken hilt‚ and chapeless; with two broken points: his horse hipped with an old mothy saddle and stirrups of

was based on the life of Laura Kieler a good friend of Ibsen. Symbolisms in literature Symbolism is when the author uses an object or reference to add deeper meaning to a story. Symbolism in literature can be subtle or obvious‚ used sparingly or heavy-handedly. An author may repeatedly use the same object to convey deeper meaning or may use variations of the same object to create an overarching mood or feeling. Symbolism is often used to support a literary theme in a subtle manner. (http://www
