Aroma compound

solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent. Because the unknown solid was insoluble in acetone, Ca(NO3)2 was then eliminated as a possible inorganic compound. The flame test did not…

Acme Products, Inc., requires a new machine to produce a part for a heat generator. Two companies have submitted bids, and you have been assigned the task of choosing one of the machines. Cash flow analysis indicates the following: Year Machine A Machine B ---- --------- --------- 0 -$1,000 -$1,000 1 0 417…

Phenacetin would mainly be in the cytosol. Our predictions were not very off. In fact, we were pretty on point thanks to the pre-lab work. We learned how to determine the polarity of the compounds from their chemical structure. We knew the order of the most hydrophilic compound and the most hydrophobic compound. Although we didn’t not complete three reliable trails, we were on point with the prediction and that makes me feel confident in the results. This experiment helped us…

Extraction was the main method of removing compounds from the sample. The component X was removed from the sample by first adding the organic solvent dichloromethane to the test tube. After aggravation, the component X dissolved into the solvent. Since components Y and Z were insoluble in the organic solvent they remained as solids. The test tube was then placed into a centrifuge and ran for thirty seconds. By doing so, the unsettled solid were forced to accumulate at the bottom of the test tube…

product in the lab. They have the ability to do this due to the molecules of the dyes possessing conjugation. Conjugation is defined as p-orbitals overlapping which causes the electrons within to be delocalized; it is also seen in molecules and compounds that contain alternating double bonds. Systems that possess conjugation absorb energy in the ultraviolet-visible region of the spectrum to cause excitement of electrons and the transitions. When the electrons get excited, they jump from lower…

A Ray of Hope Much like the dystopian and corrupt Republic in Marie Lu’s Legend, the world seems to be a sea of violence, destruction, death, and overall chaos. However, there is a way for some to survive. The American government has created vaults, or well fortified buildings, that can guarantee the safety of those inside during these hard and cruel times in the world, meaning that there is hope for some of the civilians to survive. Unfortunately, there is a keyword there and it is “some.”…

Since early human societies we have been using technology to advance and improve our lives this technology has evolved and changed with us as our societies changed. On such technology is the bow and arrow. The bow and arrow is an ancient technology which originated around the same time that the first human societies were forming. The use of the bow and arrow originated as a hunting tool in many different parts of the world. “The weapon was developed by many pre-civilized people across the world;…

passion. Through my passion for archery and bowhunting, I would make a business where I could design and manufacture compound bows for both tournament use and hunting. I believe that this business would be a good idea because bow companies and manufacturers today, concentrate too much on how the bow looks, rather than functionality, power, and technological innovation of a compound bow in this day and age could be. To better…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

the lab was to identify an unlabeled compound found in the chemistry stockroom to be able to dispose of it properly. This lab demonstrated the process of identifying an unknown compound as well as synthesizing the compound. Identifying the compound consisted of performing various tests to detect the chemical and physical properties of the compound and comparing it to the list of possible compounds. The tests conducted were the solubility test which the compound fully dissolved in water, the…
