Synthesis Essay

Conclusions For the first trial, after .398 grams of magnesium were mixed with .251 grams of oxygen, the result yielded .649 grams of magnesium oxide. In the second trial, after .404 grams of magnesium were mixed with .132 grams of oxygen, the result yielded .536 grams of magnesium oxide. In the third trial, after .406 grams of magnesium were mixed with .702 grams of oxygen, the result yielded 1.108 grams of magnesium oxide. All three of the trials yielded different results in the data table;

Through out life had taught me many things. I have found that the true happiness cannot be only achieved by hard work and acumen, but also by immense audacity for pursuing my aspirations. The profound crave for learning, invention and teaching in me lead me to continue my education for a PhD degree. My temper for science become discernible when I had sudden realization during my senior secondary school. Throughout the school I was never certain for which career path is fine for me. At that tie have

The use of beta amino acids to replace the naturally occurring alpha equivalent has recently allowed scientist to explore a more stable peptide mimic. The ability of beta-peptides to resist protease degradation has vastly improved their ability to be drug candidates as well as other therapeutic targets. As a result, it will be explored in this paper whether or not peptide mimics with beta peptide backbones are able to function as transporting polymers for short interfering RNA (siRNA). siRNA has

When I was six, I distinctly remember that my grandfather was diagnosed having an early stage colorectal cancer. He went through a major surgery and recovered with prescription drugs and herbal therapies, which appeared to have a positive additive effect. I was inspired by the ability of the pharmaceuticals in relieving my grandfather’s pain, giving him a future, and allowing me to share more memories with him. My passion in studying organic chemistry arises from me realizing there is immense potential

0274g, making the percent yield 118%. Possible explanation for a large percent yield could have been due to the product not being completely dry when being weighed or the presents of contaminates in the final product. A TLC was conducted during the synthesis of tetraphenylporphyrin; this is useful in monitoring the progression of the reaction because it helps identify what is present in the reaction in terms of starting materials and

Dealing with Learning Disabilities “He’ll know things one day, but not the next”. “She is seeing or writing words or numbers backwards.” “She has difficulty grasping simple concepts”. These are comments made by teachers who have classified certain students in their classroom as having the unfortunate burden of a learning disability. A learning disability is “a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written, which

The synthesis of alum was carried out adequately as evidenced by the correct changes in the appearances of the mixtures and compounds in various stages of the synthesis process as well as the appearance of the synthesized alum (Table I). Although the weight of the alum placed in both crucibles was similar, the weight of KAl(SO4)2 in the crucibles after heating was unequal relative to the weight of the alum (Table II). A plausible cause for such disparity could be the loss of alum due to the spattering

complex route and many issues to overcome (Huang, Wang, Chen, 2014). The reason that it is so difficult is that the researchers are attempting to fully synthesize the ingredient, hypericin, and want to do so with a great enough yield to be productive. Synthesis of hypericin without the ingredient itself has been achieved by using various routes and ending with a 50% yield. However, it was done so with many obstacles - low yield, varying routes, large volumes of solvents, the high cost of reagents and solvents

For this report I have chosen to examine audio applications. The two applications that I will discuss, compare and contrast are Ableton Live and Propellerhead Reason. Ableton Live Ableton is a music software company based in Berlin that produces and distributes the production/performance program Ableton Live and a collection of instruments and sample libraries. They also manufacture their own software controller, Ableton Push. Ableton Live is a digital audio workstation (DAW) and software music
