The Effect of Incongruent Background Color on Odor Perception The olfactory perception is the one sense that is the most difficult to describe in words. It is also a rather personal sense since people connect scents with certain memories or images of their lives. When people are asked to imagine the scent of lavender, some might think about their mother’s laundry detergent that smelled like lavender, which she used when they were younger. But to imagine scent without thinking of an actual image…

In one of the passages of Beloved, Toni Morrison mentions the fragrance of cologne in Denver's hideout, “Denver's secrets were sweet. Accompanied Everytime by wild veronica until she discovered cologne . The first bottle was a gift. The next she stole from her mother and hid among the boxwood until it froze and cracked.”(pg. 30) The cologne symbolizes Denver's sweet secrets, as she could contemplate her private thoughts without being judged in her hideout that contained the sweet fragrance of…

Inside a busy city there lays a large portrait, housed within a museum of modern art. To the untrained eye, there is nothing particularly extraordinary about it, but experts claim it is worth millions. All the while, in the outskirts of the city, a gorgeous, sprawling mural covers the side of an abandoned building, catching the attention of everyone who catches sight of it, yet it is labeled as vandalism, as mere graffiti. What is the role of art in our modern society, and what is the true…

Overall the experiment provided significant data, despite problems with reagent contamination. Iron (III)-thiocyanate complexes in equilibrium, meaning that external and internal forces on the equilibrium can shift toward the reactants or the complex. External forces are changes to the chemical or physical environment that effect the equilibrium. Internal forces are changes to the bonds or chemical nature of the complex itself. These effects are used to study the optimal chromogenic reagent,…

Hello everyone. The chemical that i’ve chosen to research is called “phthalate”, and the question I’m asking is whether it should be banned? The chemical formula for the most popular form of phthalate is C8H4O4. There is also a substance called “Phthalic acid”, from which phthalates originate, which is used to synthesize into phthalate. Some of phthalates physical properties include: a melting point of 207°, and a boiling point of 378°. It’s a colourless, white crystalline (translucent)…

Melissa Robell Ommidala Pattawong November 21st, 2014 Learning about Ammonia The chemical that I researched was Ammonia because of it’s involvement in agriculture. I am interested in agriculture and plan on majoring in Animal Science. Ammonia is an ingredient in many of the products that I use when working with animals and this made me curious. I used this opportunity to learn more about this chemical that is important in future career. Some general information about Ammonia is the chemical…

5861 What is the identity of the unknown hydrate? Hydrates are pure substances that contain water molecules embedded in their crystal structures. When a hydrate is heated the water molecules evaporate leaving behind a solid known as anhydrous. The identity of a hydrate can be found by finding out the percent water in the hydrate. The experiment was done in a manner to find the percent water in an unknown hydrate to identify the hydrate. The hydrates were BaCL2*2H2O, CuSO4*5H2O, CaCL2*2H2O, and…

3-(4-acetylphenyl)-6-bromo-2-(4-chlorophenyl)quinazolin-4(3H)-one (2) Compound 1 ( 0.01 mol) fused with p-aminoacetophenone ( 0.01 mol) at 160 oC in an oil bath for 2 h. Crystallized from ethanol to give redish brown crystals of 2, m.p. 210oC in 80% yield. Analysis for C22H14BrClN2O2, Calcd.: % C, 58.24; H, 3.11; N, 6.17, Found: % C, 58.31; H, 3.17; N, 6.20, IR spectrum (KBr, cm-1) showed characteristic absorption bands at 3380 (C-H aromatic), 1710 (C=O of acetyl), at 1690 (C=O of…

Perfumes have been used for a variety of things throughout antiquity. The uses of perfume are interesting because they were not only used to scent the body but also for medicinal purposes. While there is ample evidence for the use of them in the different places around the Mediterranean Sea, I decided to focus my experiment on a site in Pylos, Greece. Pylos contains a well excavated Mycenaean palace. My hope with this experiment is to recreate the perfume of Mycenaean Pylos, while also showing…
